在线教育项目-day12【登录接口】

1、创建service下的子模块service-ucenter

2、复制代码生成器

生成对应结构

 3、配置application.properties

# 服务端口
server.port=8001
# 服务名
spring.application.name=service-edu

# 环境设置：dev、test、prod
spring.profiles.active=dev

# mysql数据库连接
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
#Springboot2.0以上要加时区
spring.datasource.url=jdbc:mysql://localhost:3306/onlineedu?serverTimezone=GMT%2B8
spring.datasource.username=root
spring.datasource.password=123456

#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/dm/eduservice/mapper/xml/*.xml

# nacos服务地址
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848

#开启熔断机制
feign.hystrix.enabled=true

# 设置hystrix超时时间，默认1000ms
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=6000
#redis
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

#mybatis日志
mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

4.书写方法

 controller

    @PostMapping("login")
    public R login(@RequestBody LoginVo loginVo) {
        String token = memberService.login(loginVo);
        return R.OK().data("token", token);
    }

MD5

package com.dm.commonutils;

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;


public final class MD5 {

    public static String encrypt(String strSrc) {
        try {
            char hexChars[] = { '0', '1', '2', '3', '4', '5', '6', '7', '8',
                    '9', 'a', 'b', 'c', 'd', 'e', 'f' };
            byte[] bytes = strSrc.getBytes();
            MessageDigest md = MessageDigest.getInstance("MD5");
            md.update(bytes);
            bytes = md.digest();
            int j = bytes.length;
            char[] chars = new char[j * 2];
            int k = 0;
            for (int i = 0; i < bytes.length; i++) {
                byte b = bytes[i];
                chars[k++] = hexChars[b >>> 4 & 0xf];
                chars[k++] = hexChars[b & 0xf];
            }
            return new String(chars);
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
            throw new RuntimeException("MD5加密出错！！+" + e);
        }
    }

    public static void main(String[] args) {
        System.out.println(MD5.encrypt("111111"));
    }

}

serviceImpl

@Override
    public String login(LoginVo loginVo) {
        String mobile = loginVo.getMobile();
        String password = loginVo.getPassword();

        //校验参数
        if(StringUtils.isEmpty(mobile) ||
                StringUtils.isEmpty(password) ||
                StringUtils.isEmpty(mobile)) {
            throw new onlineEduException(20001,"error");
        }

        //获取会员
        UcenterMember member = baseMapper.selectOne(new QueryWrapper<UcenterMember>().eq("mobile", mobile));
        if(null == member) {
            throw new onlineEduException(20001,"error");
        }

        //校验密码
        if(!MD5.encrypt(password).equals(member.getPassword())) {
            throw new onlineEduException(20001,"error");
        }

        //校验是否被禁用
        if(member.getIsDisabled()) {
            throw new onlineEduException(20001,"error");
        }

        //使用JWT生成token字符串
        String token = JwtUtils.getJwtToken(member.getId(), member.getNickname());
        return token;
    }

但是为了测试我们先不加密

        if(!password.equals(member.getPassword())) {
            throw new onlineEduException(20001,"error");
        }

进行测试：

 等后期注册接口写完我们再把这个加密加上去

测试成功返回了一个token
