需要用到javamail的jar包，网上有。找不到把邮箱贴出来，我发给你。 package test.servlet;import java.io.IOException;
import java.io.PrintWriter;

props.put("mail.smtp.host","localhost");//存储发送邮件服务器的信息
props.put("mail.smtp.auth","true");//同时通过验证
Session s=Session.getInstance(props);//根据属性新建一个邮件会话
s.setDebug(true); //由邮件会话新建一个消息对象

InternetAddress from;

message.setFrom(from);//设置发件人
InternetAddress to=new InternetAddress(to_mail);
message.setRecipient(Message.RecipientType.TO,to);//设置收件人,并设置其接收类型为TO
message.setSubject(to_title);//设置主题
message.setText(to_content);//设置信件内容
message.setSentDate(new Date());//设置发信时间
//发送邮件
message.saveChanges();//存储邮件信息
Transport transport=s.getTransport("smtp");
//以smtp方式登录邮箱,第一个参数是发送邮件用的邮件服务器SMTP地址,第二个参数为用户名,第三个参数为密码
transport.connect("localhost",8479,"","");
transport.sendMessage(message,message.getAllRecipients());//发送邮件,其中第二个参数是所有已设好的收件人地址
