前言

下面介绍用户注册接口。

---

一、代码部分

1. User

package org.example.springboot3.bigevent.entity;import com.baomidou.mybatisplus.annotation.TableId;
import lombok.Getter;
import lombok.Setter;
import lombok.ToString;
import java.time.LocalDateTime;@Getter
@Setter
@ToString
public class User {@TableIdprivate Integer id;//主键IDprivate String username;//用户名private String password;//密码private String nickname;//昵称private String email;//邮箱private String userPic;//用户头像地址private LocalDateTime createTime;//创建时间private LocalDateTime updateTime;//更新时间
}

2.UserMapper1

package org.example.springboot3.bigevent.mapper;import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Mapper;
import org.example.springboot3.bigevent.entity.User;/*** Create by zjg on 2024/5/22*/
@Mapper
public interface UserMapper1 extends BaseMapper<User> {
}

3. UserSerivce

package org.example.springboot3.bigevent.service;import org.example.springboot3.bigevent.entity.User;/*** Create by zjg on 2024/5/22*/
public interface UserSerivce {User findUserByName(String username);int addUser(String username, String password);
}

package org.example.springboot3.bigevent.service.impl;import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import org.example.springboot3.bigevent.mapper.UserMapper1;
import org.example.springboot3.bigevent.entity.User;
import org.example.springboot3.bigevent.service.UserSerivce;
import org.example.springboot3.bigevent.utils.Md5Util;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.time.LocalDateTime;/*** Create by zjg on 2024/5/22*/
@Service
public class UserSerivceImpl implements UserSerivce {@AutowiredUserMapper1 userMapper1;@Overridepublic User findUserByName(String username) {QueryWrapper<User> queryWrapper = new QueryWrapper<>();queryWrapper.ne("username", username);return userMapper1.selectOne(queryWrapper);}@Overridepublic int addUser(String username, String password) {User user = new User();user.setUsername(username);user.setPassword(Md5Util.getMD5String(password));user.setCreateTime(LocalDateTime.now());user.setUpdateTime(LocalDateTime.now());return userMapper1.insert(user);}
}

4. UserController1

package org.example.springboot3.bigevent.controller;import org.example.springboot3.bigevent.entity.Result;
import org.example.springboot3.bigevent.entity.User;
import org.example.springboot3.bigevent.service.UserSerivce;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;/*** Create by zjg on 2024/5/22*/
@RequestMapping("/user/")
@RestController
public class UserController1 {@AutowiredUserSerivce userSerivce;@RequestMapping("register")public Result register(String username, String password){User user=userSerivce.findUserByName(username);if(user==null){//用户不存在,可以注册int i=userSerivce.addUser(username,password);if(i!=1){return Result.error("失败注册,请稍后重新注册!");}}else{return Result.error("该用户已存在,请重新注册!");}return Result.success();}
}

5. Result

package org.example.springboot3.bigevent.entity;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;//统一响应结果
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Result<T> {private Integer code;//业务状态码  0-成功  1-失败private String message;//提示信息private T data;//响应数据//快速返回操作成功响应结果(带响应数据)public static <E> Result<E> success(E data) {return new Result<>(0, "操作成功", data);}//快速返回操作成功响应结果public static Result success() {return new Result(0, "操作成功", null);}public static Result error(String message) {return new Result(1, message, null);}
}

二、测试

1.注册

2.再次注册
