springboot发送邮件任务入门(qq邮箱代码实现)

1.引入依赖

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

2.找到qq邮箱,开启smtp服务,这里生成你的密码,复制第三步用

3.password里输入你获取到的密码(重点:这里一定不能错)

[email protected]
spring.mail.password=********
spring.mail.host=smtp.qq.com
#开启加密验证
spring.mail.properties.mail.smtp.ssl.enable=true

4.EmailApplicationTests类里进行测试, contextLoads为简单的发送,仅限于文本。contextLoads2为复杂,可以发送图片,html格式

package com.xyj;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;

@SpringBootTest
class EmailApplicationTests {

    @Autowired
    JavaMailSenderImpl mailSender;

    @Test
    void contextLoads() {
        SimpleMailMessage mailMessage = new SimpleMailMessage();
        mailMessage.setSubject("你好");
        mailMessage.setText("123456");
        mailMessage.setTo("[email protected]");
        mailMessage.setFrom("[email protected]");
        mailSender.send(mailMessage);
    }


    @Test
    void contextLoads2() throws MessagingException {
        MimeMessage mimeMessage = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);

        helper.setSubject("你好");
        helper.setText("

这是红色的

",true); helper.addAttachment("bg.jpg",new File("D:\\money\\网页\\疫情\\images\\bg1.jpg")); helper.setTo("[email protected]"); helper.setFrom("[email protected]"); mailSender.send(mimeMessage); } }

5.分别对应的结果
