来源：互联网发布：tcss.ping.https.js 编辑：程序博客网时间：2024/05/30 19:32

1.在eclipse、myeclipse中创建一个web project;

2.在lib中添加必要的jar包（缺一不可）

struts-core-2.**.jar xwork-2.**.jar; commons-fileupload-**.jar;

commons-logging-**. jar; ognl-**.jar; freemarker-**.jar;

3.在web中添加filter过滤器

<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>
</filter-mapping> <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>
</filter-mapping>

4.编写action类，LoginAction

package com.action;

import com.opensymphony.xwork2.Action;

public class LoginAction implements Action {

private String username;
private String password;

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 String execute(){

if(username.equals("admin")&&password.equals("888888")){
return "success";
}
return "success";

}

}

5.进行添加struts.xml文件

<?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>
<package name="book" extends="struts-default">
<action name="login" class="com.action.LoginAction">
<result name="success">/success.jsp</result>
</action>
</package>

</struts>

6.进行添加jsp页面 login.jsp success.jsp(注意：页面中的属性元素要与Action所需要的属性元素一致)

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="gbk"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form action="login.action" method="post"> 
用户名:<input name="username"/><br>
密码:<input type="password" name="password"/><br/>
<input type="submit" value="登录">

</form>
</body>
</html>

7.进行添加tomcat服务，然后进行启动项目，进行访问http://localhost:8080/MyStruts/login.jsp即可。
