要实现邮件发送功能需要导入包：mail.jar/* * Generated by MyEclipse Struts * Template path: templates/java/JavaClass.vtl */package org.demo.action;import java.util.Properties;import javax.mail.Message;import javax.mail.Session;import javax.mail.Transport;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.struts.action.Action;import org.apache.struts.action.ActionForm;import org.apache.struts.action.ActionForward;import org.apache.struts.action.ActionMapping;import org.demo.form.DemoForm;public class DemoAction extends Action {private static final String CONTENT_TYPE = "test/html;charset=GB2312";public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) {DemoForm demoForm = (DemoForm) form;System.out.println("标题是" + demoForm.getBiaoti());System.out.println("内容是" + demoForm.getNeirong());try {response.setContentType(CONTENT_TYPE);String smtphost = "smtp.nj.headware.cn"; // 发送邮件服务器String user = "q0000015369"; // 邮件服务器登录用户名String password = "Queshuwen26"; // 邮件服务器登录密码String from = "q0000015369@nj.headware.cn"; // String to = "c0000016205@nj.headware.cn"; // 收件人邮件地址String subject = demoForm.getBiaoti(); // 邮件标题String body = demoForm.getNeirong(); // 邮件内容Properties props = new Properties();props.put("mail.smtp.host", smtphost);props.put("mail.smtp.auth", "true");Session ssn = Session.getInstance(props, null);MimeMessage message = new MimeMessage(ssn);InternetAddress fromAddress = new InternetAddress(from);message.setFrom(fromAddress);InternetAddress toAddress = new InternetAddress(to);message.addRecipient(Message.RecipientType.TO, toAddress);message.setSubject(subject);message.setText(body);Transport transport = ssn.getTransport("smtp");transport.connect(smtphost, user, password);transport.sendMessage(message, message.getRecipients(Message.RecipientType.TO));// transport.send(message);transport.close();return mapping.findForward("succ");} catch (Exception e) {e.printStackTrace();return mapping.findForward("fail");}}} ?
