先说smtp邮箱服务配置

maven-pom依赖配置

代码语言：javascript复制
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
        </dependency>

application.yml

代码语言：javascript复制
spring:
    mail:
        #配置smtp服务主机地址
        # qq邮箱为smtp.qq.com          端口号465或587
        # sina    smtp.sina.cn
        # aliyun  smtp.aliyun.com
        # 163     smtp.163.com       端口号465或994
        # 腾讯企业邮|域名邮箱 smtp.exmail.qq.com 端口号465
        host: 【自行选择】
        #发送者邮箱
        username: 【自行修改】
        #配置密码,注意不是真正的密码，而是刚刚申请到的授权码
        password: 【自行修改】
        #端口号465或587
        port: 465
        #默认的邮件编码为UTF-8
        default-encoding: UTF-8
        #其他参数
        test-connection: true
        properties:
            mail:
                smtp:
                    auth: true
                    starttls:
                        enable: true
                        required: true
                    ssl:
                        enable: true
                    socketFactory:
                        port: 465
                        class: javax.net.ssl.SSLSocketFactory

配置包装类用于读取SMTP配置

代码语言：javascript复制
/**
 * Title
 *
 * @ClassName: MailCommon
 * @Description: 读取yml-mail信息
 * @author: Karos
 * @date: 2022/10/14 1:00
 * @Blog: https://www.wzl1.top/
 */

package com.karos.td.common;


import lombok.ToString;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

//所有变量不能设置为静态变量
@Component
@ToString
public class EmailSettingCommon {
    @Value("${spring.mail.username}")
    public  String username;
    @Value("${spring.mail.host}")
    public  String host;
    @Value("${spring.mail.password}")
    public  String password;
    @Value("${spring.mail.port}")
    public  int port;
    @Value("${spring.mail.default-encoding}")
    public  String default_encoding;
}

Bean构造类

代码语言：javascript复制
/**
 * Title
 *
 * @ClassName: getBean
 * @Description:SimpleMailMessage和mail配置自动装配
 * @author: Karos
 * @date: 2022/10/15 2:54
 * @Blog: https://www.wzl1.top/
 */

package com.karos.td.common;

import org.springframework.context.annotation.Bean;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.stereotype.Component;

@Component
public class getBean {

    @Bean
    public static SimpleMailMessage smm(){
        return new SimpleMailMessage();
    }

//    @Bean
//    public static EmailSettingCommon getInstance(){
//        return new EmailSettingCommon();
//    }
}

配置邮箱服务类

代码语言：javascript复制
/**
 * Title
 *
 * @ClassName: EmailSend
 * @Description:
 * @author: Karos
 * @date: 2022/10/15 2:55
 * @Blog: https://www.wzl1.top/
 */

package com.karos.td.Util;

import com.karos.td.common.EmailSettingCommon;
import lombok.extern.log4j.Log4j2;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.stereotype.Component;

import java.util.Date;

@Component
@Log4j2
public class EmailSend {
    @Autowired
    private JavaMailSenderImpl impl;

    @Autowired
    private SimpleMailMessage smm;

    @Autowired
    private EmailSettingCommon esc;

    public void setMessage(String toMail,String Subject,String Text){
//       if (impl.getPassword()==null)SmmInit(); //如果无法读取到yml配置文件可以试一试这个，Spring自动装配@Autowired不建议使用与静态对象，@Value只有在自动装配的时候才会写入
        smm.setFrom(esc.username);
        smm.setTo(toMail);
        smm.setSubject(Subject);
        smm.setText(Text);
        smm.setSentDate(new Date());
        log.info(impl.getPassword());
    }

//    private void SmmInit(){
//        impl.setPassword(esc.password);
//        impl.setUsername(esc.username);
//        impl.setHost(esc.host);
//        impl.setDefaultEncoding(esc.default_encoding);
//        impl.setPort(esc.port);
//    }

    public void send(){
        impl.send(smm);
    }
}

验证码生成与密码加密类

代码语言：javascript复制
/**
 * Title
 *
 * @ClassName: UserSafetyUtil
 * @Description: 用户安全工具，生成验证码，密码加密等
 * @author: Karos
 * @date: 2022/10/15 9:32
 * @Blog: https://www.wzl1.top/
 */

package com.karos.td.Util;

import org.springframework.stereotype.Component;
import org.springframework.util.DigestUtils;

import java.util.Date;
import java.util.Locale;

@Component
public class UserSafetyUtil {
    public static String StrHex(StringBuffer str,StringBuffer key){
        str.append(key);
        str.insert(0,getMD5Hex(key.toString()));
        return getMD5Hex(str.insert(5,"wzl03").toString());
    }

//这个验证码获取我是瞎写的，主要还是靠时间戳来达到一个随机的效果
    public static String touchCheckCode(String str,String key){
        String s=StrHex(new StringBuffer(str),new StringBuffer(key));
        return getMD5Hex(s.substring(5,10)).substring(5,11).toUpperCase(Locale.ROOT);
    }

    public static String getMD5Hex(String str){
        return DigestUtils.md5DigestAsHex(str.getBytes());
    }

    public static String getTIMEstr() {
        return new Long((new Date().getTime()>>3|1024|8086)000).toString();
    }
}

写一个@Test

代码语言：javascript复制
package com.karos.td;

import com.karos.td.Util.EmailSend;
import com.karos.td.Util.UserSafetyUtil;
import lombok.extern.log4j.Log4j2;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
@Log4j2
class TdApplicationTests {

    @Autowired
    EmailSend ems;
    @Test
    void contextLoads() {

    }
    @Test
    void mailSend(){
        log.info("====邮件发送测试开始====");
        ems.setMessage("66985726@qq.com","测试","验证码为："  UserSafetyUtil.touchCheckCode("admin", UserSafetyUtil.getTIMEstr()));
        log.info("====邮件设定成功====");
        ems.send();
        log.info("====邮件发送成功====");
    }

}

后面的话Redis存储验证码和JJWT登录验证以后更新

tcp/ip 验证码
