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

      <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("[email protected]");
        // 接收方邮箱
        helper.setTo("[email protected]");
        // 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。
