更新時間：2017年03月16日 08:39:24 作者：Joker_Fei

這篇文章主要為大家詳細介紹了java+jsp+struts2實現(xiàn)發(fā)送郵件功能，具有一定的參考價值，感興趣的小伙伴們可以參考一下

以下總結(jié)是2016/3/23在做一個網(wǎng)站時遇到的一個功能模塊，現(xiàn)在將總結(jié)從為知筆記上搬家到CSDN，與大家共享，歡迎指正。

網(wǎng)頁顯示這里寫圖片描述

0.準備工作

　　0.1先建立一個web項目,添加struts2開發(fā)包

　　0.2.需要另外導入一下兩個jar包 mail.jar,activation.jar,可以自己網(wǎng)上下載，很多的!

以下為詳細過程!

1.index.jsp頁面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<html>
 <head>

  <title>My JSP 'index.jsp' starting page</title>
    <meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">  
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
 </head>
 <body>
  <s:form action="sendTextMail" namespace="/mail">
    <s:textfield name="to" label="收件人郵箱:"></s:textfield>
    <s:textfield name="subject" label="主題"></s:textfield>
    <s:textarea name="content" label="內(nèi)容" rows="5"></s:textarea>
    <s:submit value="發(fā)送"></s:submit>
  </s:form>
 </body>
</html>

2.SendTestAction.java類

package com.phone.action;
import java.io.PrintWriter;
import javax.servlet.http.HttpServletResponse;
import com.opensymphony.xwork2.ActionSupport;
import com.phone.util.MailSenderInfo;
import com.phone.util.SimpleMailSender;

public class SendTestAction extends ActionSupport {
  private static final long serialVersionUID = 1L;
  private String to;
  private String qq;
  private String password;
  private String subject;
  private String content;

  public String getTo() {
    return to;
  }

  public void setTo(String to) {
    this.to = to;
  }
  public String getQq() {
    return qq;
  }

  public void setQq(String qq) {
    this.qq = qq;
  }

  public String getPassword() {
    return password;
  }

  public void setPassword(String password) {
    this.password = password;
  }

  public String getSubject() {
    return subject;
  }

  public void setSubject(String subject) {
    this.subject = subject;
  }

  public String getContent() {
    return content;
  }

  public void setContent(String content) {
    this.content = content;
  }

  @Override
  public String execute() throws Exception {
    MailSenderInfo mailInfo = new MailSenderInfo();
    mailInfo.setMailServerHost("smtp.163.com");
    mailInfo.setMailServerPort("25");
    mailInfo.setValidate(true);
    mailInfo.setFromAddress("m15504506083@163.com");//自己郵箱
    mailInfo.setToAddress(to);//目標郵箱
    mailInfo.setUserName("m15504506083@163.com");//自己郵箱
    //需要開啟此郵箱的POP3/SMTP/IMAP服務，具體設置進入郵箱以后在“設置”里進行開啟
    mailInfo.setPassword("syfhhd52");//自己郵箱密碼
    //System.out.println("password="+password);
    mailInfo.setSubject(subject);
    mailInfo.setContent(content);

    boolean isSend = SimpleMailSender.sendTextMail(mailInfo);

    /*HttpServletResponse response;
    PrintWriter out = response.getWriter();*/

    if(isSend){
      return SUCCESS;
      //return out.write("<script>alert('發(fā)送成功！');history.back();</script>");

    }
    addActionError("發(fā)送失敗!");
    return INPUT;
  }
}

3.3個主要實現(xiàn)發(fā)送郵件的類

3.1 MailSenderInfo.java –郵件實體類

package com.phone.util;

import java.util.Properties;

public class MailSenderInfo {
  //發(fā)送郵件服務器IP
  private String mailServerHost ;
  //發(fā)送郵件服務器端口
  private String mailServerPort = "25";
  //郵件發(fā)送地址
  private String fromAddress;
  //郵件接受者地址
  private String toAddress;
  //發(fā)送郵件服務器的登錄用戶名
  private String userName;
  //發(fā)送郵件服務器的登錄密碼
  private String password;
  //是否需要身份驗證
  private boolean validate = false;
  //郵件主題
  private String subject;
  //郵件的文本內(nèi)容
  private String content;
  //郵件附件的文件名
  private String[] attachFileNames;
  //發(fā)送人的郵件信息,在創(chuàng)建Session是使用
  public Properties getProperties(){
    Properties p = new Properties();
    p.put("mail.smtp.host", this.mailServerHost);
    p.put("mail.smtp.port", this.mailServerPort);
    p.put("mail.smtp.auth", validate ? "true" : "false");
    return p;
  }
  public String getMailServerHost() {
    return mailServerHost;
  }
  public void setMailServerHost(String mailServerHost) {
    this.mailServerHost = mailServerHost;
  }
  public String getMailServerPort() {
    return mailServerPort;
  }
  public void setMailServerPort(String mailServerPort) {
    this.mailServerPort = mailServerPort;
  }
  public String getFromAddress() {
    return fromAddress;
  }
  public void setFromAddress(String fromAddress) {
    this.fromAddress = fromAddress;
  }
  public String getToAddress() {
    return toAddress;
  }
  public void setToAddress(String toAddress) {
    this.toAddress = toAddress;
  }
  public String getUserName() {
    return userName;
  }
  public void setUserName(String userName) {
    this.userName = userName;
  }
  public String getPassword() {
    return password;
  }
  public void setPassword(String password) {
    this.password = password;
  }
  public boolean isValidate() {
    return validate;
  }
  public void setValidate(boolean validate) {
    this.validate = validate;
  }
  public String getSubject() {
    return subject;
  }
  public void setSubject(String subject) {
    this.subject = subject;
  }
  public String getContent() {
    return content;
  }
  public void setContent(String content) {
    this.content = content;
  }
  public String[] getAttachFileNames() {
    return attachFileNames;
  }
  public void setAttachFileNames(String[] attachFileNames) {
    this.attachFileNames = attachFileNames;
  } 
}

3.2 MyAuthenticator.java —認證所需

package com.phone.util;

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

public class MyAuthenticator extends Authenticator{
  private String userName;
  private String password;


  public MyAuthenticator() {}

  public MyAuthenticator(String userName, String password) {
    this.userName = userName;
    this.password = password;
  }

  @Override
  protected PasswordAuthentication getPasswordAuthentication() {
    return new PasswordAuthentication(userName, password);
  }

}

3.3 SimpleMailSender.java –構(gòu)建發(fā)送郵件

package com.phone.util;
import java.util.Date;
import java.util.Properties;
import javax.mail.Address;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

public class SimpleMailSender {
  // 發(fā)送文本格式的郵件
  public static boolean sendTextMail(MailSenderInfo mailInfo) {

    MyAuthenticator authenticator = null;
    Properties properties = mailInfo.getProperties();
    // 如果需要身份認證，則創(chuàng)建一個密碼驗證器
    if (mailInfo.isValidate()) {
      authenticator = new MyAuthenticator(mailInfo.getUserName(),
          mailInfo.getPassword());
    }
    // 根據(jù)發(fā)件人的服務器信息和發(fā)件人用戶名和密碼構(gòu)造一個發(fā)送郵件的session
    Session sendMailSession = Session.getDefaultInstance(properties,
        authenticator);
    try {
      // 根據(jù)session創(chuàng)建一個郵件消息
      Message mailMessage = new MimeMessage(sendMailSession);
      // 創(chuàng)建郵件發(fā)送者地址
      Address from = new InternetAddress(mailInfo.getFromAddress());
      // 設置郵件消息的發(fā)送者
      mailMessage.setFrom(from);
      // 創(chuàng)建郵件的接收者地址，并設置到郵件消息中
      Address to = new InternetAddress(mailInfo.getToAddress());
      mailMessage.setRecipient(Message.RecipientType.TO, to);
      // 設置郵件消息的主題
      mailMessage.setSubject(mailInfo.getSubject());
      // 設置郵件消息發(fā)送的時間
      mailMessage.setSentDate(new Date());
      // 設置郵件消息的主要內(nèi)容
      String mailContent = mailInfo.getContent();
      mailMessage.setText(mailContent);
      // 發(fā)送郵件
      Transport.send(mailMessage);
      return true;
    } catch (Exception e) {
      e.printStackTrace();
    }

    return false;
  }

  // 發(fā)送HTML格式的郵件
  public static boolean sendHtmlMail(MailSenderInfo mailInfo) {
    // 判斷是否需要身份認證
    MyAuthenticator authenticator = null;
    Properties pro = mailInfo.getProperties();
    // 如果需要身份認證，則創(chuàng)建一個密碼驗證器
    if (mailInfo.isValidate()) {
      authenticator = new MyAuthenticator(mailInfo.getUserName(),
          mailInfo.getPassword());
    }
    // 根據(jù)郵件會話屬性和密碼驗證器構(gòu)造一個發(fā)送郵件的session
    Session sendMailSession = Session.getInstance(pro, authenticator);
    try {
      // 根據(jù)session創(chuàng)建一個郵件消息
      Message mailMessage = new MimeMessage(sendMailSession);
      // 創(chuàng)建郵件發(fā)送者地址
      Address from = new InternetAddress(mailInfo.getFromAddress());
      // 設置郵件消息的發(fā)送者
      mailMessage.setFrom(from);
      // 創(chuàng)建郵件的接收者地址，并設置到郵件消息中
      Address to = new InternetAddress(mailInfo.getToAddress());
      // Message.RecipientType.TO屬性表示接收者的類型為TO
      mailMessage.setRecipient(Message.RecipientType.TO, to);
      // 設置郵件消息的主題
      mailMessage.setSubject(mailInfo.getSubject());
      // 設置郵件消息發(fā)送的時間
      mailMessage.setSentDate(new Date());
      // MiniMultipart類是一個容器類，包含MimeBodyPart類型的對象
      Multipart mainPart = new MimeMultipart();
      // 創(chuàng)建一個包含HTML內(nèi)容的MimeBodyPart
      BodyPart html = new MimeBodyPart();
      // 設置HTML內(nèi)容
      html.setContent(mailInfo.getContent(), "text/html;charset=utf-8");
      mainPart.addBodyPart(html);
      // 將MiniMultipart對象設置為郵件內(nèi)容
      mailMessage.setContent(mainPart);
      // 發(fā)送郵件
      Transport.send(mailMessage);
      return true;
    } catch (MessagingException ex) {
      ex.printStackTrace();
    }
    return false;
  }
}

4. struts.xml配置

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
 <!-- 設置瀏覽器不緩存 -->
  <constant name="struts.serve.static.browserCache" value="false"></constant>
  <!-- 修改XML后不重啟自動加載 -->
  <constant name="struts.configuration.xml.reload" value="true"></constant>
  <!-- 打印更詳細的錯誤信息 -->
  <constant name="struts.devMode" value="true"></constant>
  <package name="mail" namespace="/mail" extends="struts-default">
    <action name="sendTextMail" class="com.phone.action.SendTestAction">
      <result name="success">/success.jsp</result>
      <result name="input">/index.jsp</result>
    </action>
  </package>
</struts>

注意：

登陸所用郵箱必須開啟POP3/SMTP/IMAP服務，登陸郵箱，點擊“設置”進行開啟。
