### 说明 ###

*  spring提供了非常好用的`JavaMailSender`接口实现了邮件的发送，其中Spring Boot的Starter也为此提供了自动化配置
 *  QQ邮箱需要发送方开启smtp和获取授权码，开启方法：[http://service.mail.qq.com/cgi-bin/help?subtype=1&&no=1001256&&id=28][http_service.mail.qq.com_cgi-bin_help_subtype_1_no_1001256_id_28]

<dependency>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-mail</artifactId>
              <version>2.0.2.RELEASE</version>
          </dependency>

### application.properties配置 ###

# 发送方电子邮箱服务器，如果是163就是stmp.163.com
    spring.mail.host=smtp.qq.com
    # 发送方邮箱
    spring.mail.username=发送方邮箱
    # 如果是QQ邮箱，就是发送方授权码
    spring.mail.password=发送方授权码
    # 通过验证
    spring.mail.properties.mail.smtp.auth=true
    spring.mail.properties.mail.smtp.starttls.enable=true
    spring.mail.properties.mail.smtp.starttls.required=true

### 测试 ###

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.javamail.JavaMailSender;
    import org.springframework.mail.javamail.MimeMailMessage;
    import org.springframework.mail.javamail.MimeMessageHelper;
    import org.springframework.test.context.junit4.SpringRunner;
    
    import javax.mail.internet.MimeMessage;
    
    @RunWith(SpringRunner.class)
    @SpringBootTest
    public class SendemailApplicationTests {
    
        @Autowired
        private JavaMailSender javaMailSender;
    
        @Test
        public void contextLoads() throws Exception{
            MimeMessage mimeMessage = javaMailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
            // 发送方邮箱
            helper.setFrom("sender@qq.com");
            // 接收方邮箱
            helper.setTo("receiver@qq.com");
            // 主题
            helper.setSubject("主题：测试邮件");
            // 内容
            helper.setText("邮箱测试Test");
            javaMailSender.send(mimeMessage);
    
        }
    
    }

最后PO个效果图，QAQ请忽略我多年前青涩的非主流昵称。
