    // === 主键字段（根据表DDL自适应） ===

    // --- 方式1: JeecgBoot 标准字符串主键 (varchar(36)/varchar(32), 无AUTO_INCREMENT) ---
    // @TableId(type = IdType.ASSIGN_ID)
    // @Schema(description = "主键")
    // private String id;

    // --- 方式2: int 自增主键 (int AUTO_INCREMENT) ---
    // @TableId(type = IdType.AUTO)
    // @Schema(description = "主键")
    // private Integer id;

    // --- 方式3: bigint 自增主键 (bigint AUTO_INCREMENT) ---

    // @TableId(type = IdType.ASSIGN_ID)
    // @Schema(description = "主键")
    // private Long id;

    // === 业务字段（根据需求生成） ===
    // 每个业务字段按以下规则生成注解：

    // --- String 字段 ---
    // @Excel(name = "字段注释", width = 15)
    // private String fieldName;

    // --- 带字典的 String 字段 ---
    // @Excel(name = "字段注释", width = 15, dicCode = "dict_code")
    // @Dict(dicCode = "dict_code")
    // private String fieldName;

    // --- 关联表字典的 String 字段 ---
    // @Excel(name = "字段注释", width = 15, dictTable = "sys_user", dicText = "realname", dicCode = "username")
    // @Dict(dictTable = "sys_user", dicText = "realname", dicCode = "username")
    // private String fieldName;

    // --- Integer 字段 ---
    // @Excel(name = "字段注释", width = 15)
    // private Integer fieldName;

    // --- BigDecimal 字段 ---
    // @Excel(name = "字段注释", width = 15)
    // private BigDecimal fieldName;

    // --- Date 字段 ---
    // @Excel(name = "字段注释", width = 15, format = "yyyy-MM-dd")
    // @JsonFormat(timezone = "GMT+8", pattern = "yyyy-MM-dd")
    // @DateTimeFormat(pattern = "yyyy-MM-dd")
    // private Date fieldName;

    // --- DateTime 字段 ---
    // @Excel(name = "字段注释", width = 20, format = "yyyy-MM-dd HH:mm:ss")
    // @JsonFormat(timezone = "GMT+8", pattern = "yyyy-MM-dd HH:mm:ss")
    // @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    // private Date fieldName;

    // === 系统字段（仅在表中实际存在时才生成，不要盲目添加！） ===

    // --- 以下每个字段都需要检查表DDL中是否存在对应列，不存在则不生成 ---

    // 如果表有 create_by 列:
    // /**创建人*/
    // @Schema(description = "创建人")
    // private String createBy;

    // 如果表有 create_time 列:
    // /**创建日期*/
    // @JsonFormat(timezone = "GMT+8", pattern = "yyyy-MM-dd HH:mm:ss")
    // @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    // @Schema(description = "创建日期")
    // private Date createTime;

    // 如果表有 update_by 列:
    // /**更新人*/
    // @Schema(description = "更新人")
    // private String updateBy;

    // 如果表有 update_time 列:
    // /**更新日期*/
    // @JsonFormat(timezone = "GMT+8", pattern = "yyyy-MM-dd HH:mm:ss")
    // @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    // @Schema(description = "更新日期")
    // private Date updateTime;

    // 如果表有 sys_org_code 列:
    // /**所属部门*/
    // @Schema(description = "所属部门")
    // private String sysOrgCode;

    // 新建表时默认添加全部系统字段；已有表按实际DDL决定。
}
```

**字典注解规则：**
- 下拉/单选/多选/搜索框 + 字典编码: `@Dict(dicCode = "xxx")`
- 下拉/单选/多选/搜索框 + 字典表: `@Dict(dictTable = "tableName", dicText = "textField", dicCode = "codeField")`
- 用户选择: `@Dict(dictTable = "sys_user", dicText = "realname", dicCode = "username")`
- 部门选择: `@Dict(dictTable = "sys_depart", dicText = "depart_name", dicCode = "id")`

**注意：** 如果查询字段中有下拉/单选/多选/复选框类型的，需要添加自定义查询规则：
```java
// 在 queryPageList 方法中：
Map<String, QueryRuleEnum> customeRuleMap = new HashMap<>();
customeRuleMap.put("status", QueryRuleEnum.LIKE_WITH_OR);
QueryWrapper<{{entityName}}> queryWrapper = QueryGenerator.initQueryWrapper({{entityName_uncap}}, req.getParameterMap(), customeRuleMap);

### A7. API文件 (vue3 和 vue3Native 通用)

```typescript
import { defHttp } from '/@/utils/http/axios';
import { useMessage } from '/@/hooks/web/useMessage';

const { createConfirm } = useMessage();

enum Api {
  list = '/{{entityPackagePath}}/{{entityName_uncap}}/list',
  save = '/{{entityPackagePath}}/{{entityName_uncap}}/add',
  edit = '/{{entityPackagePath}}/{{entityName_uncap}}/edit',
  deleteOne = '/{{entityPackagePath}}/{{entityName_uncap}}/delete',
  deleteBatch = '/{{entityPackagePath}}/{{entityName_uncap}}/deleteBatch',
  importExcel = '/{{entityPackagePath}}/{{entityName_uncap}}/importExcel',
  exportXls = '/{{entityPackagePath}}/{{entityName_uncap}}/exportXls',
}

/**
 * 导出api
 */
export const getExportUrl = Api.exportXls;

/**
 * 导入api
 */
export const getImportUrl = Api.importExcel;

/**
 * 列表接口
 * @param params
 */
export const list = (params) => defHttp.get({ url: Api.list, params });

/**
 * 删除单个
 */
export const deleteOne = (params, handleSuccess) => {
  return defHttp.delete({ url: Api.deleteOne, params }, { joinParamsToUrl: true }).then(() => {
    handleSuccess();
  });
};

/**
 * 批量删除
 * @param params
 */
export const batchDelete = (params, handleSuccess) => {
  createConfirm({
    iconType: 'warning',
    title: '确认删除',
    content: '是否删除选中数据',
    okText: '确认',
    cancelText: '取消',
    onOk: () => {
      return defHttp.delete({ url: Api.deleteBatch, data: params }, { joinParamsToUrl: true }).then(() => {
        handleSuccess();
      });
    },
  });
};

/**
 * 保存或者更新
 * @param params
 * @param isUpdate
 */
export const saveOrUpdate = (params, isUpdate) => {
  let url = isUpdate ? Api.edit : Api.save;
  return defHttp.post({ url: url, params });
};
```

**vue3Native 风格差异：** `saveOrUpdate` 使用 `{ isTransformResponse: false }` 选项：
```typescript
export const saveOrUpdate = (params, isUpdate) => {
  let url = isUpdate ? Api.edit : Api.save;
  return defHttp.post({ url: url, params }, { isTransformResponse: false });
};
```

// 高级查询配置
export const superQuerySchema = {

  // datetimeField: { title: '日期时间', order: 3, view: 'datetime' },
  // quantity: { title: '数量', order: 4, view: 'number' },
};
```

**高级查询 view 类型映射：**
- string → `text`
- int/double/BigDecimal → `number`
- date → `date`
- datetime → `datetime`
- 字典字段(list/radio/checkbox) → `list`, 带 `dictCode`
- 关联表字典 → `list_multi` 或 `sel_search`, 带 `dictTable/dictCode/dictText`
- switch → `radio`
- user_select → `sel_user`
- dept_select → `sel_depart`

### A8N. Data文件 - vue3Native 原生风格

vue3Native 的 data.ts 只包含 columns 和 superQuerySchema，不包含 formSchema（表单在模板中直接写控件）。

```typescript
import { BasicColumn } from '/@/components/Table';
import { FormSchema } from '/@/components/Table';
import { rules } from '/@/utils/helper/validator';
import { render } from '/@/utils/common/renderUtils';

// 列表列定义（与 vue3 封装风格完全相同）
export const columns: BasicColumn[] = [
  // ... 同 A8 的 columns
];

// 高级查询配置（与 vue3 封装风格完全相同）
export const superQuerySchema = {
  // ... 同 A8 的 superQuerySchema
};
```

## B. 树表模式差异

树表在单表基础上有以下差异：

### B1. Entity 额外字段

```java
    /**父级节点*/
    @Excel(name = "父级节点", width = 15)
    @Schema(description = "父级节点")
    private String pid;
    /**是否有子节点*/
    @Excel(name = "是否有子节点", width = 15, dicCode = "yn")
    @Dict(dicCode = "yn")
    @TableField(value = "has_child")
    @Schema(description = "是否有子节点")
    private String hasChild;
```

### B2. Mapper 额外方法

```java
public interface {{entityName}}Mapper extends BaseMapper<{{entityName}}> {

    /**
     * 编辑节点状态
     */
    @Update("update {{tableName}} set has_child=#{hasChild} where id = #{pid}")
    void updateTreeNodeStatus(@Param("pid") String pid, @Param("hasChild") String hasChild);

    /**
     * 根据pid查询子节点
     */
    @Select("select * from {{tableName}} where pid = #{parentId} ${installCondition}")
    List<{{entityName}}> queryListByPid(@Param("parentId") String parentId, @Param("installCondition") String installCondition);
}
```

### B3. Service 接口额外方法

```java
public interface I{{entityName}}Service extends IService<{{entityName}}> {
    public static final String ROOT_PID_VALUE = "0";
    public static final String HASCHILD = "1";
    public static final String NOCHILD = "0";

    void add{{entityName}}({{entityName}} entity);
    void update{{entityName}}({{entityName}} entity);
    void delete{{entityName}}(String id) throws JeecgBootException;
    List<{{entityName}}> queryTreeListNoPage(QueryWrapper<{{entityName}}> queryWrapper);
    List<{{entityName}}> queryListByCode(String code);
    List<{{entityName}}> queryListByPid(String pid);
}
```

### B4. ServiceImpl 核心逻辑

```java
@Service
public class {{entityName}}ServiceImpl extends ServiceImpl<{{entityName}}Mapper, {{entityName}}> implements I{{entityName}}Service {

    @Override
    public void add{{entityName}}({{entityName}} entity) {
        if (oConvertUtils.isEmpty(entity.getPid())) {
            entity.setPid(I{{entityName}}Service.ROOT_PID_VALUE);
        } else {
            // 如果当前节点父ID不为空 则设置父节点的hasChild为1
            {{entityName}} parent = baseMapper.selectById(entity.getPid());
            if (parent != null && !I{{entityName}}Service.HASCHILD.equals(parent.getHasChild())) {
                parent.setHasChild(I{{entityName}}Service.HASCHILD);
                baseMapper.updateById(parent);
            }
        }
        baseMapper.insert(entity);
    }

    @Override
    public void update{{entityName}}({{entityName}} entity) {
        {{entityName}} old = baseMapper.selectById(entity.getId());
        if (old != null && !old.getPid().equals(entity.getPid())) {
            // 更新新父节点状态
            updateOldParentNode(entity.getPid());
            // 更新旧父节点状态（检查是否还有子节点）
            int childCount = baseMapper.selectCount(new QueryWrapper<{{entityName}}>().eq("pid", old.getPid())).intValue();
            if (childCount == 1) {
                // 当前是唯一子节点，更新旧父为无子节点
                if (!I{{entityName}}Service.ROOT_PID_VALUE.equals(old.getPid())) {
                    baseMapper.updateTreeNodeStatus(old.getPid(), I{{entityName}}Service.NOCHILD);
                }
            }
        }
        baseMapper.updateById(entity);
    }

    @Override
    @Transactional(rollbackFor = Exception.class)
    public void delete{{entityName}}(String id) throws JeecgBootException {
        // 查询选中节点下所有子节点一起删除
        id = TreeUtils.getTreeChildIds(id, (pid) -> baseMapper.queryListByPid(pid, null));
        if (id.indexOf(",") > 0) {
            baseMapper.deleteBatchIds(Arrays.asList(id.split(",")));
        } else {
            baseMapper.deleteById(id);
        }
        // 更新父节点状态
        {{entityName}} entity = baseMapper.selectById(id.split(",")[0]);
        if (entity != null) {
            updateOldParentNode(entity.getPid());
        }
    }

    private void updateOldParentNode(String pid) {
        if (!I{{entityName}}Service.ROOT_PID_VALUE.equals(pid)) {
            {{entityName}} parent = baseMapper.selectById(pid);
            if (parent != null) {
                parent.setHasChild(I{{entityName}}Service.HASCHILD);
                baseMapper.updateById(parent);
            }
        }
    }
}
```

### B5. Controller 额外端点

```java
    /**
     * 查询根节点数据
     */
    @GetMapping(value = "/rootList")
    public Result<IPage<{{entityName}}>> rootList({{entityName}} entity,

                                                   @RequestParam(name = "pageSize", defaultValue = "10") Integer pageSize,
                                                   HttpServletRequest req) {
        // 判断有没有查询条件，如果有则按条件查全部（不分树层级）
        String hasQuery = req.getParameter("hasQuery");
        if (oConvertUtils.isNotEmpty(hasQuery) && "true".equals(hasQuery)) {
            QueryWrapper<{{entityName}}> queryWrapper = QueryGenerator.initQueryWrapper(entity, req.getParameterMap());
            Page<{{entityName}}> page = new Page<>(pageNo, pageSize);

        queryWrapper.eq("pid", I{{entityName}}Service.ROOT_PID_VALUE);
        Page<{{entityName}}> page = new Page<>(pageNo, pageSize);
        IPage<{{entityName}}> pageList = {{entityName_uncap}}Service.page(page, queryWrapper);
        return Result.OK(pageList);
    }

    /**

     */
    @GetMapping(value = "/childList")
    public Result<List<{{entityName}}>> childList({{entityName}} entity,

        IPage<{{entityName}}> pageList = new Page<>(1, 10, list.size());
        pageList.setRecords(list);
        return Result.OK(pageList);
    }
```

### B6. 树表前端 API 额外方法

```typescript
enum Api {
  list = '/{{entityPackagePath}}/{{entityName_uncap}}/rootList',  // 注意是 rootList
  // ... 其他同单表
  loadTreeData = '/{{entityPackagePath}}/{{entityName_uncap}}/rootList',
  getChildList = '/{{entityPackagePath}}/{{entityName_uncap}}/childList',
  getChildListBatch = '/{{entityPackagePath}}/{{entityName_uncap}}/getChildListBatch',
}

// 额外导出
export const loadTreeData = (params) => defHttp.get({ url: Api.loadTreeData, params });
export const getChildList = (params) => defHttp.get({ url: Api.getChildList, params });
export const getChildListBatch = (params) => defHttp.get({ url: Api.getChildListBatch, params }, { isTransformResponse: false });
```

### B7. 树表前端 List 页面差异

vue3 封装风格中 `useListPage` 的 `tableProps` 增加：
```typescript
tableProps: {
  // ... 同单表
  isTreeTable: true,  // 标记为树表
  // list API 改为 rootList
}
```

模板中增加展开/加载子节点逻辑（参考 `src/views/system/category/index.vue`）。

## C. 一对多模式差异

一对多在单表基础上有以下差异：

### C1. 子表 Entity

每个子表生成独立的 Entity，包含外键字段：
```java
    /**主表ID（外键）*/
    @Schema(description = "主表ID")
    private String {{mainEntityName_uncap}}Id;  // 外键字段名默认为 主表实体名(camelCase) + Id
```
注意：子表 Entity 的外键字段不加 `@Excel` 注解（导出时忽略）。

### C2. 子表 Mapper

```java
public interface {{subEntityName}}Mapper extends BaseMapper<{{subEntityName}}> {
    /**
     * 通过主表id删除子表数据
     */
    @Delete("DELETE FROM {{subTableName}} WHERE {{foreignKey}} = #{mainId}")
    boolean deleteByMainId(@Param("mainId") String mainId);

    /**
     * 通过主表id查询子表数据
     */
    List<{{subEntityName}}> selectByMainId(@Param("mainId") String mainId);
}
```

### C3. 主表 Service 接口

```java
public interface I{{entityName}}Service extends IService<{{entityName}}> {
    /**
     * 添加一对多
     */
    public void saveMain({{entityName}} entity, List<{{subEntityName}}> subList);

    /**
     * 修改一对多
     */
    public void updateMain({{entityName}} entity, List<{{subEntityName}}> subList);

    /**
     * 删除一对多
     */
    public void delMain(String id);

    /**
     * 批量删除一对多
     */
    public void delBatchMain(Collection<? extends Serializable> idList);
}
```

### C4. 主表 ServiceImpl

```java
@Service
public class {{entityName}}ServiceImpl extends ServiceImpl<{{entityName}}Mapper, {{entityName}}> implements I{{entityName}}Service {

    @Autowired
    private {{subEntityName}}Mapper {{subEntityName_uncap}}Mapper;

    @Override
    @Transactional(rollbackFor = Exception.class)
    public void saveMain({{entityName}} entity, List<{{subEntityName}}> subList) {
        baseMapper.insert(entity);
        if (subList != null && subList.size() > 0) {
            for ({{subEntityName}} sub : subList) {
                sub.set{{mainEntityName}}Id(entity.getId());  // 设置外键
                {{subEntityName_uncap}}Mapper.insert(sub);
            }
        }
    }

    @Override
    @Transactional(rollbackFor = Exception.class)
    public void updateMain({{entityName}} entity, List<{{subEntityName}}> subList) {
        baseMapper.updateById(entity);
        // 先删后增
        {{subEntityName_uncap}}Mapper.deleteByMainId(entity.getId());
        if (subList != null && subList.size() > 0) {
            for ({{subEntityName}} sub : subList) {
                sub.set{{mainEntityName}}Id(entity.getId());
                {{subEntityName_uncap}}Mapper.insert(sub);
            }
        }
    }

    @Override
    @Transactional(rollbackFor = Exception.class)
    public void delMain(String id) {
        {{subEntityName_uncap}}Mapper.deleteByMainId(id);
        baseMapper.deleteById(id);
    }

    @Override
    @Transactional(rollbackFor = Exception.class)
    public void delBatchMain(Collection<? extends Serializable> idList) {
        for (Serializable id : idList) {
            {{subEntityName_uncap}}Mapper.deleteByMainId(id.toString());
            baseMapper.deleteById(id);
        }
    }
}
```

### C5. Page VO（Excel导入导出用）

```java
package org.jeecg.modules.{{entityPackage}}.vo;

import org.jeecg.modules.{{entityPackage}}.entity.{{entityName}};
import org.jeecg.modules.{{entityPackage}}.entity.{{subEntityName}};
import lombok.Data;
import org.jeecgframework.poi.excel.annotation.ExcelCollection;
import java.util.List;

@Data
public class {{entityName}}Page {
    // 主表字段（同 Entity，不含系统字段）
    // ...

    @ExcelCollection(name = "{{subDescription}}")
    private List<{{subEntityName}}> {{subEntityName_uncap}}List;
}
```

### C6. Controller 额外端点

```java
    /**
     * 查询子表数据
     */
    @GetMapping(value = "/query{{subEntityName}}ByMainId")
    public Result<List<{{subEntityName}}>> query{{subEntityName}}ByMainId(@RequestParam(name = "id", required = true) String id) {
        List<{{subEntityName}}> list = {{subEntityName_uncap}}Mapper.selectByMainId(id);
        return Result.OK(list);
    }
```

### C7. 前端差异

主要差异在于编辑 Modal/Form 中包含子表的 Tab 页或内嵌表格：
- 主表字段 + 子表 Tab（使用 `a-tabs` 切换）
- 子表使用 `JEditableTable` 或 `BasicTable` 展示和编辑
- 保存时收集主表 + 子表数据一起提交

## E. 建表 DDL 模板（如需要自动建表）

```sql
CREATE TABLE `{{tableName}}` (
  `id` varchar(36) NOT NULL COMMENT '主键',
  -- 业务字段
  -- `field_name` varchar(100) DEFAULT NULL COMMENT '字段注释',
  `create_by` varchar(50) DEFAULT NULL COMMENT '创建人',
  `create_time` datetime DEFAULT NULL COMMENT '创建日期',
  `update_by` varchar(50) DEFAULT NULL COMMENT '更新人',
  `update_time` datetime DEFAULT NULL COMMENT '更新日期',
  `sys_org_code` varchar(64) DEFAULT NULL COMMENT '所属部门',
  PRIMARY KEY (`id`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='{{description}}';
```

树表额外字段：
```sql
  `pid` varchar(36) DEFAULT NULL COMMENT '父级节点',
  `has_child` varchar(3) DEFAULT NULL COMMENT '是否有子节点',
```

子表额外字段：
```sql
  `{{main_table_name}}_id` varchar(36) DEFAULT NULL COMMENT '主表外键',
```

---

## F. 增量字段修改（加字段/删字段/改字段）

### F1. 定位已有代码文件

增量修改时，必须先找到并读取所有相关文件：

```
后端文件（在后端根目录搜索）：
  - **/entity/{EntityName}.java          → 实体类
  - **/controller/{EntityName}Controller.java  → 控制器（通常不需要改）
  - **/service/I{EntityName}Service.java       → Service接口（通常不需要改）
  - **/service/impl/{EntityName}ServiceImpl.java → Service实现（通常不需要改）

前端文件（在前端 src/views/ 下搜索）：
  - **/{EntityName}.data.ts              → 列定义 + 表单Schema
  - **/{EntityName}List.vue              → 列表页（通常不需要改）
  - **/{EntityName}Modal.vue             → 弹窗（通常不需要改）
  - **/{EntityName}Form.vue              → 表单（vue3Native风格，需要改）
```

### F2. 加字段 — 需要修改的位置

**每加一个字段，需要修改以下文件：**

#### 1) Entity.java — 在业务字段区域末尾追加

根据字段类型选择对应的注解模式（参考 A1 节的业务字段模板）：

```java
// String 字段
@Excel(name = "字段注释", width = 15)
@Schema(description = "字段注释")
private String fieldName;

// 带字典的 String 字段
@Excel(name = "字段注释", width = 15, dicCode = "dict_code")
@Dict(dicCode = "dict_code")
@Schema(description = "字段注释")
private String fieldName;

// Integer 字段
@Excel(name = "字段注释", width = 15)
@Schema(description = "字段注释")
private Integer fieldName;

// BigDecimal 字段（需确认 import java.math.BigDecimal 已存在）
@Excel(name = "字段注释", width = 15)
@Schema(description = "字段注释")
private BigDecimal fieldName;

// Date 字段（需确认 import java.util.Date + JsonFormat + DateTimeFormat 已导入）
@Excel(name = "字段注释", width = 15, format = "yyyy-MM-dd")
@JsonFormat(timezone = "GMT+8", pattern = "yyyy-MM-dd")
@DateTimeFormat(pattern = "yyyy-MM-dd")
@Schema(description = "字段注释")
private Date fieldName;

// DateTime 字段
@Excel(name = "字段注释", width = 20, format = "yyyy-MM-dd HH:mm:ss")
@JsonFormat(timezone = "GMT+8", pattern = "yyyy-MM-dd HH:mm:ss")
@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
@Schema(description = "字段注释")
private Date fieldName;
```

**注意：** 检查是否需要新增 import 语句（如 BigDecimal、Date、JsonFormat、Dict 等）。

#### 2) *.data.ts — 三处追加

**a) columns 数组末尾追加列定义：**
```typescript
// 普通列
{
  title: '字段名称',
  align: 'center',
  dataIndex: 'fieldName',
},
// 字典列（dataIndex 加 _dictText 后缀）
{
  title: '状态',
  align: 'center',
  dataIndex: 'status_dictText',
},
// 图片列
{
  title: '图片',
  align: 'center',
  dataIndex: 'imageField',
  customRender: render.renderImage,
},
```

**b) searchFormSchema 数组追加查询条件（仅常用查询字段需要）：**
```typescript
{
  label: '字段名称',
  field: 'fieldName',
  component: 'JInput',  // 或 JDictSelectTag 等
  colProps: { span: 6 },
},
```

**c) formSchema 数组末尾追加（在最后一个字段 `}` 后、`];` 前）：**
```typescript
{
  label: '字段名称',
  field: 'fieldName',
  component: 'Input',  // 根据字段类型选择组件
  componentProps: { placeholder: '请输入字段名称' },
},
```

**d) superQuerySchema 数组追加（如果存在）：**
```typescript
{ title: '字段名称', value: 'fieldName', type: 'string' },
```

#### 3) *Form.vue — 仅 vue3Native 风格需要修改

在 `<a-form>` 中追加表单项：
```vue
<a-form-item label="字段名称" v-bind="validatorRules.fieldName" name="fieldName">
  <a-input v-model:value="formData.fieldName" placeholder="请输入字段名称" />
</a-form-item>
```

在 `formData` reactive 对象中追加初始值：
```typescript
fieldName: '',
```

#### 4) Flyway SQL — 生成 ALTER TABLE

```sql
ALTER TABLE `{{tableName}}` ADD COLUMN `column_name` varchar(100) DEFAULT NULL COMMENT '字段注释';
```

多个字段可合并为一条 ALTER：
```sql
ALTER TABLE `{{tableName}}`
  ADD COLUMN `field1` varchar(100) DEFAULT NULL COMMENT '注释1',
  ADD COLUMN `field2` int DEFAULT NULL COMMENT '注释2';
```

### F3. 删字段 — 需要修改的位置

**从以下位置移除字段相关代码：**

1. **Entity.java** — 删除字段声明及其注解（@Excel、@Dict、@Schema、@JsonFormat 等）
2. ***.data.ts** — 删除 columns 中对应列、searchFormSchema 中对应项、formSchema 中对应项、superQuerySchema 中对应项
3. ***Form.vue**（vue3Native）— 删除 `<a-form-item>` 和 formData 中对应属性
4. **Flyway SQL** — 生成 `ALTER TABLE \`{{tableName}}\` DROP COLUMN \`column_name\`;`

**注意：** 删除 Entity 字段后检查是否有不再使用的 import（如删除了唯一的 BigDecimal 字段，则移除 BigDecimal import）。

### F4. 改字段 — 需要修改的位置

根据修改内容，可能需要改动：

- **改类型**：Entity 字段类型 + data.ts 组件类型 + Form.vue 控件 + ALTER TABLE MODIFY
- **改注释/标题**：Entity @Excel name + @Schema description + data.ts title/label
- **加/改字典**：Entity @Dict + data.ts 组件改为 JDictSelectTag + columns dataIndex 加 _dictText
- **改必填**：data.ts formSchema 中 required 属性

Flyway SQL 示例：
```sql
ALTER TABLE `{{tableName}}` MODIFY COLUMN `column_name` decimal(10,2) DEFAULT NULL COMMENT '新注释';
```

### F5. 增量修改检查清单

每次增量修改完成后，确认：
- [ ] Entity.java — 字段声明 + 注解 + import
- [ ] *.data.ts — columns + searchFormSchema(如需) + formSchema + superQuerySchema(如存在)
- [ ] *Form.vue — 表单控件 + formData 初始值（仅 vue3Native）
- [ ] Flyway SQL — ALTER TABLE 语句
- [ ] 无遗漏的 import 增删
