javamail文件上传

//创建entity

package cn.bdqn.pojo;

import java.io.File;

public class Mail {

    private String from;

    private String to;

    private String subject;

    private String content;

    private File file;

    private String fileName;

    public Mail(){}

    public Mail(String from, String to, String subject, String content, File file, String fileName){

        this.from = from;

        this.to = to;

        this.subject = subject;

        this.content = content;

        this.file = file;

        this.fileName = fileName;

    }

    public String getFrom() {

        return from;

    }

    public void setFrom(String from) {

        this.from = from;

    }

    public String getTo() {

        return to;

    }

    public void setTo(String to) {

        this.to = to;

    }

    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 File getFile() {

        return file;

    }

    public void setFile(File file) {

        this.file = file;

    }

    public String getFileName() {

        return fileName;

    }

    public void setFileName(String fileName) {

        this.fileName = fileName;

    }

}

2.创建service

package cn.bdqn.service;

import javax.mail.internet.MimeMessage;

import javax.mail.internet.MimeUtility;

import org.springframework.mail.javamail.JavaMailSender;

import org.springframework.mail.javamail.MimeMessageHelper;

import cn.bdqn.pojo.Mail;

public class MailService {

    private JavaMailSender mailSender;

    public void setMailSender(JavaMailSender mailSender) {

        this.mailSender = mailSender;

    }

    public void sendMail(Mail mail){

        try{

            MimeMessage mimeMessage = mailSender.createMimeMessage();

            MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true, "UTF-8");

            helper.setFrom(mail.getFrom());

            helper.setTo(mail.getTo());

            helper.setSubject(mail.getSubject());

            helper.setText(mail.getContent());

            helper.addAttachment(MimeUtility.encodeWord(mail.getFileName()),mail.getFile());

            mailSender.send(mimeMessage);

        }catch(Exception e){

            e.printStackTrace();

        }

    }

}

3.创建action

package cn.bdqn.action;

import java.io.File;

import org.junit.Test;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.bdqn.pojo.Mail;

import cn.bdqn.service.MailService;

import com.opensymphony.xwork2.ActionContext;

import com.opensymphony.xwork2.ActionSupport;

public class SendMailAction extends ActionSupport{

    private static final long serialVersionUID = 1L;

    private MailService mailService =null;

    private String from;

    private String to;

    private String subject;

    private String content;

    private File upload;

    private String uploadFileName;

    @Override

    public String execute() throws Exception {

        Mail mail = new Mail(getFrom(),getTo(),getSubject(),getContent(),getUpload(),getUploadFileName());

        mailService.sendMail(mail);

        return "success";

    }

    @Test

    public void test1(){

        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

        MailService service=(MailService)context.getBean("mailService");

        Mail mail = new Mail(getFrom(),getTo(),getSubject(),getContent(),getUpload(),getUploadFileName());

        service.sendMail(mail);

        System.out.println("ok!");

    }

    public void setMailService(MailService mailService) {

        this.mailService = mailService;

    }

    public File getUpload() {

        return upload;

    }

    public void setUpload(File upload) {

        this.upload = upload;

    }

    public String getFrom() {

        return from;

    }

    public void setFrom(String from) {

        this.from = from;

    }

    public String getTo() {

        return to;

    }

    public void setTo(String to) {

        this.to = to;

    }

    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 getUploadFileName() {

        return uploadFileName;

    }

    public void setUploadFileName(String uploadFileName) {

        this.uploadFileName = uploadFileName;

    }

}

4、applicationXml:

<?xml version="1.0" encoding="UTF-8"?>

<beans

    xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xmlns:p="http://www.springframework.org/schema/p"

    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">

    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">

        <property name="host" value="smtp.qq.com"></property><!-- 服务器 -->

        <property name="port" value="465"></property><!-- 端口 -->

        <property name="username" value="[email protected]"></property><!-- 用户名 -->

        <property name="password" value="123.shuai-+.0"></property><!-- 密码 -->

        <property name="protocol" value="SSL" ></property><!-- 协议 -->

        <property name="defaultEncoding" value="utf-8"></property><!-- 默认编码 -->

        <property name="javaMailProperties">

            <props>

                <!-- 设置SMTP服务器需要用户验证  -->

                <prop key="mail.smtp.auth">true</prop>

            </props>

        </property>

    </bean>

    <bean id="mailService" class="cn.bdqn.service.MailService">

        <property name="mailSender" ref="mailSender"></property>

    </bean>

</beans>

6、创建struts.xml

<?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>

    <constant name="struts.i18n.encoding" value="UTF-8"/>

    <package name="default" namespace="/" extends="struts-default">

        <action name="sendmailAction" class="cn.bdqn.action.SendMailAction">

            <result name="success">/sendmail_success.jsp</result>

        </action>

    </package>

</struts>    

6、创建web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="3.0"

    xmlns="http://java.sun.com/xml/ns/javaee"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

  <display-name></display-name>

  <welcome-file-list>

    <welcome-file>index.jsp</welcome-file>

  </welcome-file-list>

  <!-- struts2的配置文件 -->

  <filter>

      <filter-name>struts2</filter-name>

      <filter-class>

          org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

      </filter-class>

  </filter>

  <filter-mapping>

      <filter-name>struts2</filter-name>

      <!-- <url-pattern>*.action</url-pattern> -->

      <url-pattern>/*</url-pattern>

  </filter-mapping>

  <!-- Spring的配置信息 -->

  <context-param>

    <param-name>contextConfigLocation</param-name>

    <param-value>classpath:applicationContext.xml</param-value>

  </context-param>

   <listener>

      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

   </listener>

   <!-- <filter>

     <filter-name>OpenSessionInViewFilter</filter-name>

     <filter-class>

        org.springframework.orm.hibernate3.support.OpenSessionInViewFilter

     </filter-class>

   </filter> -->

   <!-- <filter-mapping>

      <filter-name>OpenSessionInViewFilter</filter-name>

      <url-pattern>*.action</url-pattern>

   </filter-mapping> -->

</web-app>

7、创建接收用户信息界面

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<%@taglib uri="/struts-tags"  prefix="s"%>

<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

  <head>

    <base href="<%=basePath%>">

    <title>邮件发送页</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">

    <!--

    <link rel="stylesheet" type="text/css" href="styles.css">

    -->

  </head>

  <body>

    <H2>邮件发送</H2><br>

    <s:form action="sendmailAction" enctype="multipart/form-data" method="post">

        <s:textfield name="from" label="发件人" value="[email protected]"/>

        <s:textfield name="to" label="收件人"/>

        <s:textfield name="subject" label="主题"/>

        <s:textarea name="content" label="内容"/>

        <s:file name="upload" lable="选择附件"/>

        <s:submit name="submit" value="发送邮件"/>

    </s:form>

  </body>

</html>

8、成功页面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%@taglib uri="/struts-tags"  prefix="s"%>

<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

  <head>

    <base href="<%=basePath%>">

    <title>成功页</title>

    <meta http-equiv="pragma" content="no-cache">

    <meta http-equiv="cache-control" content="no-cache">
