# Java实体类编写规范

## 基本结构

实体类必须遵循以下结构:

1. **文件头注释**:包含版权信息、作者、日期
2. **包声明**:使用小写字母,多个单词直接连接(如:`com.skyeye.abnormalmarking.entity`)
3. **导入语句**:按需导入
4. **类注释**:包含 `@ClassName`、`@Description`、`@author`、`@date`、`@Copyright`
5. **类注解**:`@Data`、`@TableName`、`@ApiModel` 等
6. **字段定义**:使用 `@TableField` 和 `@ApiModelProperty` 注解

## 注解使用规范

### 必需注解
- `@Data` - Lombok注解,自动生成getter/setter
- `@TableName(value = "表名")` - MyBatis Plus表名映射
- `@ApiModel("实体类描述")` - API文档注解

### 可选注解
- `@UniqueField` - 唯一字段标识(如果实体有唯一字段)
- `@RedisCacheField(name = "缓存key")` - Redis缓存配置
- `@TableField(exist = false)` - 非数据库字段标识

### 字段注解
- `@TableField("字段名")` - 数据库字段映射
- `@ApiModelProperty(value = "字段描述", required = "required")` - API文档字段说明
- `@Property(value = "字段描述")` - 用于非数据库字段的说明

## 继承规范

根据业务需求选择合适的基类:
- `BaseGeneralInfo` - 通用实体(包含标准字段:create_id, create_time, last_update_id, last_update_time, tenant_id)
- `Version` - 版本管理实体(包含版本号相关字段)
- `SkyeyeFlowable` - 工作流实体(包含流程相关字段)
- `CommonInfo` - 通用信息实体(用于子表)

## 字段命名规范

- 使用驼峰命名:`projectId`、`schemeCode`
- 布尔字段使用 `is`/`has`/`can` 前缀:`isEnabled`、`hasPermission`
- 关联对象使用 `Mation` 后缀:`projectMation`、`objectMation`
- 列表字段使用 `List` 后缀:`budgetDetailList`、`bomChildList`
