操作：查询列表

主要看DAO层和XML映射

1.controller层

@PostMapping    @ApiOperation("用户列表")    @ApiImplicitParams({@ApiImplicitParam(name = "userName", value = "用户名称", required = false, paramType = "query", dataType = "String")})    public ResponseResult listUser(QueryUser user) {        return UserService.listUser(user);    }

2.Service层

public ResponseResult listUser(QueryUser user) {        PageHelper.startPage(user.getPageNum(), user.getPageSize());        String userName = ParamUtil.like(user.getUserName());        List
   
    
     > list = UserDao.listUser(userName);        ParamUtil.addr("userAddressId", list, addressDao);        return new ResponseResult(new PageInfo
     
      
       >(list));    }
      
     
    
   

3.Dao层

List
   
    
     > listUser(@Param("userName") String userName);
    
   

4. xml映射

        select                    from User where 1=1 and user_delete_flag = 0                        and user_name like #{userName}                order by             user_creat_time desc
