-
@Test
simple code // Send mail
-
public void testSimpleEmail() throws Exception {
-
SimpleEmail email =
new new

// create a simple email subject
-
// Here I use the QQ, using smtp server requires authentication, if you are using another server, you can go to their Web search
-
email.setHostName(
"smtp.qq.com");
-
//POP3服务器（端口995）
-
//SMTP服务器（端口465或587）。

//完成附件设置
-
attachment.setDescription(

//设置附件的名称
-
//创建email对象(MultiPartEmail可以操作附件)
-
MultiPartEmail email =
new MultiPartEmail();
-

效果图：
第一步：项目引入相应资源 commons-email-xx.jar，mail.jar，activation.jar
