公共字段自动填充

不足

比起瑞吉外卖中的用自定义元数据类型+mybatisplus的实现，这里使用的是aop切面实现，会麻烦许多，建议升级为mp。

定义好数据库操作类型

sky-common中已经定义好，OperationType。

自定义注解 AutoFill

com.sky.annotation.AutoFill

/*** 自定义注解，用于标识某个方法需要进行功能字段自动填充处理*/
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface AutoFill {//数据库操作类型：UPDATE INSERTOperationType value();
}

自定义切面 AutoFillAspect

com.sky.aspect.AutoFillAspect


@Slf4j
public class AutoFillAspect {/*** 切入点*/@Pointcut("execution(* com.sky.mapper.*.*(..)) && @annotation(com.sky.annotation.AutoFill)")public void autoFillPointCut(){}/*** 前置通知，在通知中进行公共字段的赋值*/@Before("autoFillPointCut()")public void autoFill(JoinPoint joinPoint){//可先进行调试，是否能进入该方法 提前在mapper方法添加AutoFill注解log.info("开始进行公共字段自动填充...");//步骤一：获取到当前被拦截的方法上的数据库操作类型MethodSignature signature = (MethodSignature) joinPoint.getSignature();//获得方法签名对象AutoFill autoFill = signature.getMethod().getAnnotation(AutoFill.class);//获得方法上的注解对象OperationType operationType = autoFill.value();//获得数据库操作类型//步骤二：获取到当前被拦截的方法的参数，即实体对象Object[] args = joinPoint.getArgs();if(args == null || args.length == 0){return;}Object entity = args[0];//步骤三：准备赋值的数据LocalDateTime now = LocalDateTime.now();Long currentid = BaseContext.getCurrentId();/*步骤四：根据当前不同的操作类型，为对应的属性通过反射来赋值。之所以不直接通过set等方法赋值，是因为获取到的实体类对象可能不一样。譬如这里该项目就可能为员工或者菜品使用set方法需要强转为某个实体类对象。*/if(operationType == OperationType.INSERT){try{Method setCreateTime = entity.getClass().getDeclaredMethod(AutoFillConstant.SET_CREATE_TIME, LocalDateTime.class);Method setCreateUser = entity.getClass().getDeclaredMethod(AutoFillConstant.SET_CREATE_USER, Long.class);Method setUpdateTime = entity.getClass().getDeclaredMethod(AutoFillConstant.SET_UPDATE_TIME, LocalDateTime.class);Method setUpdateUser = entity.getClass().getDeclaredMethod(AutoFillConstant.SET_UPDATE_USER, Long.class);//通过反射为对象属性赋值setCreateTime.invoke(entity,now);setCreateUser.invoke(entity,currentid);setUpdateTime.invoke(entity,now);setUpdateUser.invoke(entity,currentid);} catch (Exception e) {e.printStackTrace();}}else if(operationType == OperationType.UPDATE) {//为2个公共字段赋值try {Method setUpdateTime = entity.getClass().getDeclaredMethod(AutoFillConstant.SET_UPDATE_TIME, LocalDateTime.class);Method setUpdateUser = entity.getClass().getDeclaredMethod(AutoFillConstant.SET_UPDATE_USER, Long.class);//通过反射为对象属性赋值setUpdateTime.invoke(entity, now);setUpdateUser.invoke(entity, currentid);} catch (Exception e) {e.printStackTrace();}}}
}

在mapper上增加自定义注解autofill

com.sky.mapper.CategoryMapper

    @AutoFill(value = OperationType.INSERT)void insert(Category category);@AutoFill(value = OperationType.UPDATE)void update(Category category);

com.sky.mapper.EmployeeMapper

 	@AutoFill(value = OperationType.INSERT)void insert(Employee employee);@AutoFill(value = OperationType.UPDATE)void update(Employee employee);

删除/注释掉业务层原先为公共字段赋值的语句

com.sky.service.impl.CategoryServiceImpl

/*** 分类业务层*/
@Service
@Slf4j
public class CategoryServiceImpl implements CategoryService {@Autowiredprivate CategoryMapper categoryMapper;@Autowiredprivate DishMapper dishMapper;@Autowiredprivate SetmealMapper setmealMapper;/*** 新增分类* @param categoryDTO*/public void save(CategoryDTO categoryDTO) {Category category = new Category();//属性拷贝BeanUtils.copyProperties(categoryDTO, category);//分类状态默认为禁用状态0category.setStatus(StatusConstant.DISABLE);//设置创建时间、修改时间、创建人、修改人
//        category.setCreateTime(LocalDateTime.now());
//        category.setUpdateTime(LocalDateTime.now());
//        category.setCreateUser(BaseContext.getCurrentId());
//        category.setUpdateUser(BaseContext.getCurrentId());categoryMapper.insert(category);}/*** 分页查询* @param categoryPageQueryDTO* @return*/public PageResult pageQuery(CategoryPageQueryDTO categoryPageQueryDTO) {PageHelper.startPage(categoryPageQueryDTO.getPage(),categoryPageQueryDTO.getPageSize());//下一条sql进行分页，自动加入limit关键字分页Page<Category> page = categoryMapper.pageQuery(categoryPageQueryDTO);return new PageResult(page.getTotal(), page.getResult());}/*** 根据id删除分类* @param id*/public void deleteById(Long id) {//查询当前分类是否关联了菜品，如果关联了就抛出业务异常Integer count = dishMapper.countByCategoryId(id);if(count > 0){//当前分类下有菜品，不能删除throw new DeletionNotAllowedException(MessageConstant.CATEGORY_BE_RELATED_BY_DISH);}//查询当前分类是否关联了套餐，如果关联了就抛出业务异常count = setmealMapper.countByCategoryId(id);if(count > 0){//当前分类下有菜品，不能删除throw new DeletionNotAllowedException(MessageConstant.CATEGORY_BE_RELATED_BY_SETMEAL);}//删除分类数据categoryMapper.deleteById(id);}/*** 修改分类* @param categoryDTO*/public void update(CategoryDTO categoryDTO) {Category category = new Category();BeanUtils.copyProperties(categoryDTO,category);//        //设置修改时间、修改人
//        category.setUpdateTime(LocalDateTime.now());
//        category.setUpdateUser(BaseContext.getCurrentId());categoryMapper.update(category);}/*** 启用、禁用分类* @param status* @param id*/public void startOrStop(Integer status, Long id) {Category category = Category.builder().id(id).status(status)
//                .updateTime(LocalDateTime.now())
//                .updateUser(BaseContext.getCurrentId()).build();categoryMapper.update(category);}/*** 根据类型查询分类* @param type* @return*/public List<Category> list(Integer type) {return categoryMapper.list(type);}
}

com.sky.service.impl.EmployeeServiceImpl

@Service
