个人选择的发送服务服务器是QQ，所以要进行开启QQ邮箱的SMTP服务，过程如图所示：

## 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![Center 1][] ##

EmailSendTest:

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

个人成功测试图如下：
