java登录注册功能实现、用户登录注册接口（四）

一、基本配置application.properties


# 服务端口
server.port=8080
# 服务名
spring.application.name=service

# mysql数据库连接
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/DB?serverTimezone=GMT%2B8
spring.datasource.username=root
spring.datasource.password=root

spring.redis.host=127.0.0.1
spring.redis.port=6379
spring.redis.database= 0
spring.redis.timeout=1800000
spring.redis.lettuce.pool.max-active=20
spring.redis.lettuce.pool.max-wait=-1
#最大阻塞等待时间(负数表示没限制)
spring.redis.lettuce.pool.max-idle=5
spring.redis.lettuce.pool.min-idle=0
#最小空闲

#返回json的全局时间格式
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8

#配置mapper xml文件的路径
mybatis-plus.mapper-locations=classpath:com/jzd/centerService/mapper/xml/*.xml

二、创建登录和注册接口

package com.jzd.centerService.controller;


import com.jzd.centerService.entity.UcenterMember;
import com.jzd.centerService.entity.vo.RegisterVo;
import com.jzd.centerService.service.CenterMemberService;
import com.jzd.commonUtils.JwtUtils;
import com.jzd.commonUtils.Result;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import javax.servlet.http.HttpServletRequest;

/**
 * <p>
 * 会员表 前端控制器
 * </p>
 *
 * @author jzd
 * @since 2020-08-08
 */
@CrossOrigin
@RestController
@RequestMapping("/")
public class CenterMemberController {
    @Autowired
    private CenterMemberService centerMemberService;

    //登录
    @PostMapping("/login")
    public Result login(@RequestBody UcenterMember centerMember){
        String token = centerMemberService.loginUser(centerMember);
        return Result.ok().data("token",token);
    }

    //注册
    @PostMapping("/register")
    public Result register(@RequestBody RegisterVo registerVo){
        centerMemberService.registerUser(registerVo);
        return Result.ok();
    }

    // 根据token获取用户信息
    @GetMapping("/getMemberInfo")
    public Result getMemberInfo(HttpServletRequest request){
        String jwtToken = JwtUtils.getMemberIdByJwtToken(request);
        UcenterMember member = centerMemberService.getById(jwtToken);
        return Result.ok().data("userInfo",member);
    }

}

三、创建service接口和实现类

package com.jzd.centerService.service.impl;

import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.jzd.centerService.entity.UcenterMember;
import com.jzd.centerService.entity.vo.RegisterVo;
import com.jzd.centerService.mapper.CenterMemberMapper;
import com.jzd.centerService.service.CenterMemberService;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.jzd.commonUtils.JwtUtils;
import com.jzd.commonUtils.MD5;
import com.jzd.serviceBase.exceptionHandler.EduException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Service;
import org.springframework.util.StringUtils;

/**
 * <p>
 * 会员表 服务实现类
 * </p>
 *
 * @author jzd
 * @since 2020-08-08
 */
@Service
public class CenterMemberServiceImpl extends ServiceImpl<CenterMemberMapper, UcenterMember> implements CenterMemberService {

    //  Redis注入
    @Autowired
    private RedisTemplate<String, String> redisTemplate;

    //登录
    @Override
    public String loginUser(UcenterMember centerMember) {
        String mobile = centerMember.getMobile();
        String password = centerMember.getPassword();

        if ((StringUtils.isEmpty(mobile))  || StringUtils.isEmpty(password)){
            throw new EduException(20001,"登录失败");
        }

        QueryWrapper<UcenterMember> wrapper = new QueryWrapper<>();
        wrapper.eq("mobile",mobile);
        //查询结果
        UcenterMember mobileMember = baseMapper.selectOne(wrapper);

        //手机号判断
        if (mobileMember == null) {
            throw new EduException(20001,"登录失败,手机号不能为空");
        }

        //密码
        if (!MD5.encrypt(password).equals(mobileMember.getPassword())) {
            throw new EduException(20001,"登录失败，密码错误");
        }

        //是否禁用
        if (mobileMember.getIsDisabled()) {
            throw new EduException(20001,"登录失败，禁止登录");
        }

        //登录成功，生成token字符串
        String jwtToken = JwtUtils.getJwtToken(mobileMember.getId(), mobileMember.getNickname());
        return jwtToken;
    }

    //注册
    @Override
    public void registerUser(RegisterVo registerVo) {
        String code = registerVo.getCode();
        String mobile = registerVo.getMobile();
        String nickname = registerVo.getNickname();
        String password = registerVo.getPassword();

        //非空校验参数
        if(StringUtils.isEmpty(mobile) ||
                StringUtils.isEmpty(mobile) ||
                StringUtils.isEmpty(password) ||
                StringUtils.isEmpty(code)) {
            throw new EduException(20001,"注册失败");
        }

        //判断验证码与redis中的是否一致
        //从redis获取发送的验证码
        String redisCode = redisTemplate.opsForValue().get(mobile);
        if(!code.equals(redisCode)) {
            throw new EduException(20001,"注册失败");
        }

        //查询数据库中是否存在相同的手机号码
        Integer count = baseMapper.selectCount(new QueryWrapper<UcenterMember>().eq("mobile", mobile));
        if(count.intValue() > 0) {
            throw new EduException(20001,"注册失败");
        }

        //添加注册信息到数据库
        UcenterMember member = new UcenterMember();
        member.setNickname(nickname);
        member.setMobile(registerVo.getMobile());
        member.setPassword(MD5.encrypt(password));
        member.setIsDisabled(false);
        member.setAvatar("https://picsum.photos/id/1010/367/267");
        this.save(member);
    }

}
