用springBoot发送邮件

导入发送Mail依赖

        
            org.springframework.boot
            spring-boot-starter-mail
        

配置mail

spring.mail.username=2034281742@qq.com
spring.mail.password=iqmbatnwddzydfgb
#是什么邮箱就 smtp.XX.com
spring.mail.host=smtp.qq.com
#qq需要开启加密验证
spring.mail.properties.mail.smtp.ssl.enable=true

编写简单邮件

 @Async //告诉spring这是一个异步方法
    public void sendMail(){  //简单邮箱
        SimpleMailMessage message = new SimpleMailMessage();
        message.setSubject("这是lzl通过java程序发送的测试邮件");
        message.setText("这是正文");
        message.setTo("2034281742@qq.com");
        message.setFrom("2034281742@qq.com");
        senderMail.send(message);
        System.out.println("邮件已发送");
    }

编写一个复杂邮件

 @Async
    public void sendMimeMail() throws MessagingException { //发送复杂邮件
        MimeMessage mimeMessage = senderMail.createMimeMessage();
        MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage,true); //开启multipart，以实现发送附件
        messageHelper.setSubject("这是lzl通过java程序发送的测试邮件");
        messageHelper.setText("
这是正文
",true);
        //附件
        messageHelper.addAttachment("图片1",new File("D:\\Instalaltion package\\sunDowm.jpg"));
        messageHelper.addAttachment("图片2",new File("D:\\Instalaltion package\\sunDowm.jpg"));
        messageHelper.setTo("2034281742@qq.com");
        messageHelper.setFrom("2034281742@qq.com");
        senderMail.send(mimeMessage);
    }

实现

package com.Google.controller;


import com.Google.service.TimeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.stereotype.Repository;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.mail.MessagingException;

@RestController
public class mailController {
    @Autowired
    TimeService timeService;

    @RequestMapping("/mail")
    public String sendMail() throws InterruptedException, MessagingException {
        timeService.sendMimeMail();
        timeService.sendMail();
        timeService.timeSleep();
        return "邮件已发送！请耐心等待";
    }
}

启动

package com.Google;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableAsync;

@SpringBootApplication
@EnableAsync//开启异步功能
public class SpringBoot07MailTestApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringBoot07MailTestApplication.class, args);
    }

}
