Joker_Fei 通过本文主要向大家介绍了jsp struts2,struts2重定向到jsp,struts2 jsp取值,struts2拦截jsp页面,struts2跳转jsp等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
以下总结是2016/3/23在做一个网站时遇到的一个功能模块，现在将总结从为知笔记上搬家到CSDN，与大家共享，欢迎指正。
0.准备工作
0.1先建立一个web项目,添加struts2开发包
0.2.需要另外导入一下两个jar包 mail.jar,activation.jar,可以自己网上下载，很多的!
以下为详细过程!
1.index.jsp页面
<%@ 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="收件人邮箱:"></s:textfield>
<s:textfield name="subject" label="主题"></s:textfield>
<s:textarea name="content" label="内容" rows="5"></s:textarea>
<s:submit value="发送"></s:submit>
</s:form>
</body>
</html>
</div>
2.SendTestAction.java类
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");//自己邮箱
mailInfo.setToAddress(to);//目标邮箱
mailInfo.setUserName("m15504506083@163.com");//自己邮箱
//需要开启此邮箱的POP3/SMTP/IMAP服务，具体设置进入邮箱以后在“设置”里进行开启
mailInfo.setPassword("syfhhd52");//自己邮箱密码
//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('发送成功！');history.back();</script>");
}
addActionError("发送失败!");
return INPUT;
}
}
</div>
3.3个主要实现发送邮件的类
3.1 MailSenderInfo.java –邮件实体类
package com.phone.util;
import java.util.Properties;
public class MailSenderInfo {
//发送邮件服务器IP
private String mailServerHost ;
//发送邮件服务器端口
private String mailServerPort = "25";
//邮件发送地址
private String fromAddress;
//邮件接受者地址
private String toAddress;
//发送邮件服务器的登录用户名
private String userName;
//发送邮件服务器的登录密码
private String password;
//是否需要身份验证
private boolean validate = false;
//邮件主题
private String subject;
//邮件的文本内容
private String content;
//邮件附件的文件名
private String[] attachFileNames;
//发送人的邮件信息,在创建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;
}
}
</div>
3.2 MyAuthenticator.java —认证所需
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);
}
}
</div>
3.3 SimpleMailSender.java –构建发送邮件
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
