表结构设计

create table tb_user(
user_id bigint unsigned NOT NULL COMMENT '用户id（主键）',
nick_name varchar(20) comment '用户昵称',
head_image varchar(100) comment '用户头像',
sex tinyint comment '用户状态1：男 2：女',
phone char(11) not null comment '手机号',
code char(6) comment '验证码',
email varchar(20) comment '邮箱',
wechat varchar(20) comment '微信号',
school_name varchar(20) comment '学校',
major_name varchar(20) comment '专业',
introduce varchar(100) comment '个人介绍',
status tinyint not null comment '用户状态0：拉黑 1：正常',
create_by bigint unsigned not null comment '创建人',
create_time datetime not null comment '创建时间',
update_by bigint unsigned comment '更新人',
update_time datetime comment '更新时间',
primary key(`user_id`)
)

用户列表功能

后端代码

Controller

package com.bite.system.controller;import com.bite.common.core.controller.BaseController;
import com.bite.common.core.vo.TableDataInfo;
import com.bite.system.model.user.DTO.UserQueryDTO;
import com.bite.system.service.impl.user.IUserService;

import org.springframework.web.bind.annotation.RestController;@RestController
@RequestMapping("/user")
public class UserController extends BaseController {@Autowiredprivate IUserService userService;@GetMapping("/list")public TableDataInfo list(UserQueryDTO userQueryDTO) {return getDataTable(userService.list(userQueryDTO));}
}

DTO

Vo

import com.fasterxml.jackson.databind.ser.std.ToStringSerializer;
import lombok.Getter;
import lombok.Setter;@Getter
@Setter
public class UserVO {@JsonSerialize(using = ToStringSerializer.class)private Long userId;private String nickName;private Integer sex;private String phone;private String email;private String wechat;private String schoolName;private String majorName;private String introduce;private Integer status;
}

Entity

package com.bite.system.model.user;import com.baomidou.mybatisplus.annotation.IdType;

import com.baomidou.mybatisplus.annotation.TableName;
import com.bite.common.core.domain.BaseEntity;

}

Service

package com.bite.system.service.impl.user.imp;import com.bite.system.mapper.user.UserMapper;
import com.bite.system.model.user.DTO.UserQueryDTO;
import com.bite.system.model.user.vo.UserVO;

public class UserServiceImpl implements IUserService {@Autowiredprivate UserMapper userMapper;@Overridepublic List<UserVO> list(UserQueryDTO userQueryDTO) {PageHelper.startPage(userQueryDTO.getPageNum(), userQueryDTO.getPageSize());return userMapper.selectUserList(userQueryDTO);}}

Mapper

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.bite.system.model.user.DTO.UserQueryDTO;
import com.bite.system.model.user.User;
import com.bite.system.model.user.vo.UserVO;import java.util.List;public interface UserMapper extends BaseMapper<User> {List<UserVO> selectUserList(UserQueryDTO userQueryDTO);
}

Mapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.bite.system.mapper.user.UserMapper"><select id="selectUserList" resultType="com.bite.system.model.user.vo.UserVO">SELECTuser_id,nick_name,sex,phone,email,wechat,school_name,major_name,introduce,statusFROMtb_user<where><if test="userId !=null ">user_id = #{userId}</if><if test="nickName !=null and nickName != ''">AND nick_name like concat('%', #{nickName}, '%')</if></where>ORDER BYcreate_time DESC</select>
</mapper>

修改用户状态功能

后端代码

Controller

  @PutMapping("/updateStatus")//todo 拉黑：限制用户操作   解禁：放开对于用户限制//更新数据库中用户的状态信息。public R<Void> updateStatus(@RequestBody UserDTO userDTO) {return toR(userService.updateStatus(userDTO));}

DTO

@Getter
@Setter
public class UserDTO {private Long userId;private Integer status;
}

Service

这里逻辑和代码都很简单，就是去数据库里面查找到用户，然后修改用户的状态，然后再存入数据库里面

 @Overridepublic int updateStatus(UserDTO userDTO) {User user = userMapper.selectById(userDTO.getUserId());if (user == null) {throw new ServiceException(ResultCode.FAILED_USER_NOT_EXISTS);}user.setStatus(userDTO.getStatus());return userMapper.updateById(user);}

前端代码

cuser.js

import service from '@/utils/request'export function getUserListService(params) {return service({url: "/user/list",method: "get",params,});
}export function updateStatusService(params = {}) {return service({url: "/user/updateStatus",method: "put",data: params,});
}

cuser.vue
