Spring JavaMailSender发送邮件

在账户下设置开启SMTP服务，需记住显示的STMP密码，点击“开启”后发短信过去即可开启

import org.junit.Test;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;

import java.util.Properties;

public class MailSendTest {
@Test
public void springEmailSender() throws IOException {
JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
//服务器SMTP域，可百度自行搜索对应域
mailSender.setHost("smtp.qq.com");
mailSender.setDefaultEncoding("UTF-8");
//发送方服务邮箱
mailSender.setUsername("你的账号@qq.com");
//发送方SMTP密码(并非你的QQ密码)
mailSender.setPassword("16位的SMTP密码");
Properties props = new Properties();
//加载根目录下的mail.properties文件
props.load(ClassLoader.getSystemResourceAsStream("mail.properties"));
//设置email会话
mailSender.setSession(Session.getInstance(props));

//新建邮件
SimpleMailMessage mailMessage = new SimpleMailMessage();
//收件人邮箱
mailMessage.setTo("接收方邮箱@163.com");
//邮件标题
mailMessage.setSubject("测试邮件");
//邮件发送方邮箱，若与username值相同将抛出from与username不符的异常
mailMessage.setFrom("发送方邮箱@qq.com");
//邮件内容
mailMessage.setText("a test email");

//进行邮件发送
mailSender.send(mailMessage);
}
}



根目录下的资源文件mail.properties：

#若不设置将抛出iis security异常
mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
mail.smtp.socketFactory.port=465
