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 org.demo.form.DemoForm

public class DemoAction extends Action {

private static final String CONTENT_TYPE = "test/htmlcharset=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 = "[email protected]"//

String to = "[email protected]"// 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")

}

}

}

Java中可以通过Javamail API实现公司邮箱邮件发送配置，Java mail是利用现有的邮箱账户发送邮件的工具，具体步骤如如下：

1、通过JavamailAPI设置发送者邮箱用户名及密码

2、通过JavamailAPI设置邮件主题、邮件内容、附件及邮件发送时间
