spring boot发邮件

项目地址：https://gitee.com/indexman/spring_boot_in_action

在task模块下，我写了test类

邮件发送流程：

发件方：836491384@qq.com

收件方：indexman@126.com

配置pom.xml

添加mail依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

登录QQ邮箱，开启pop3和smtp服务

发送短信后，点击【我已发送】会生成一串密码，将此密码填入application.properties中的

spring.mail.password=wlcfnoewxzuebabc

配置application.properties

spring.mail.host=smtp.qq.com
spring.mail.username=836491384@qq.com
spring.mail.password=wlcfnoewxzuebabc
spring.mail.properties.mail.smtp.ssl.enable=true

编写测试方法

package com.laoxu.springboot;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.test.context.junit4.SpringRunner;

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

@RunWith(SpringRunner.class)
@SpringBootTest
public class TaskApplicationTests {
    @Autowired
    JavaMailSenderImpl mailSender;

    @Test
    public void contextLoads() {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setSubject("今晚开会");
        message.setText("大家，好！\n今晚7:30在教学楼201开班委会，请各位班委准时参加！ \n谢谢！");
        message.setTo("indexman@126.com");
        message.setFrom("836491384@qq.com");

        mailSender.send(message);
    }

    @Test
    public void test2() throws Exception{
        MimeMessage mimeMessage = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);
        helper.setSubject("今晚开会");
        helper.setText("大家，好！<br> &nbsp;&nbsp;<b style='color:red'>今晚7:30在教学楼201开班委会，请各位班委准时参加！</b> <br>谢谢！",true);
        helper.setTo("indexman@126.com");
        helper.setFrom("836491384@qq.com");

        //添加附件
        helper.addAttachment("会议说明.txt",new File("C:\\Users\\Dylan\\Pictures\\会议说明.txt"));
        helper.addAttachment("会议图片.jpg",new File("C:\\Users\\Dylan\\Pictures\\会议图片.jpg"));

        mailSender.send(mimeMessage);
    }

}
