进阶之路002 增删改查/数据导入导出之删除功能

Controller层

/**
* 删除
*/
@ResponseBody
@RequestMapping("/delete")
@RequiresPermissions("xxxx:detail:delete")
public R delete(@RequestBody Integer[] ids){
detailService.removeByIds(Arrays.asList(ids));

return R.ok();
}

//Service接口

 boolean removeByIds(Collection<? extends Serializable> idList);

//接口实现类

//baseMapper中已经设置好了权限分配（框架自带）

@Override
public boolean removeByIds(Collection<? extends Serializable> idList) {
return SqlHelper.retBool(baseMapper.deleteBatchIds(idList));
}

//dao层

//批量删除

 int deleteBatchIds(@Param(Constants.COLLECTION) Collection<? extends Serializable> idList);
