struts环境搭建

structs环境搭建很简单，只需要三步即可（hibernate,spring也是相同的）

1，导入jar包（jar包下载地址：http://pan.baidu.com/s/1bSc5ye）

2，修改配置文件

3，然后进行测试

接下来我把每个步骤的详细信息写下来，一定要自己跟着做，切忌不要只看不敲。

1：创建一个web工程，并把下载好的jar包全部复制到到/WEB-INF/lib目录下

2，把structs.xml文件放到src目录下，并在/WEB-INF下的web.xml中设置过滤器

structs.xml代码如下:

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"    "http://struts.apache.org/dtds/struts-2.0.dtd"><struts>    <constant name="struts.enable.DynamicMethodInvocation" value="false" />    <constant name="struts.devMode" value="false" />    <package name="default" namespace="/" extends="struts-default">        <action name="test_*" class="cn.wxz.Login.LoginAction" method="{1}">            <result>/WEB-INF/jsp/success.jsp </result>             <result name="error">/WEB-INF/jsp/error.jsp </result>        </action>    </package></struts>

web.xml的代码如下:

<?xml version="1.0" encoding="UTF-8"?><web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">    <display-name>Struts Blank</display-name>    <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>    <welcome-file-list>        <welcome-file>index.jsp</welcome-file>    </welcome-file-list></web-app>

3:进行测试，创建一个类继承ActionSupport，并且在/WEB-INF下创建一个jsp文件夹在 jap文件夹下创建两个页面一个是成功页面（success.jsp）另一个是失败页面（error.jsp）,在/WEB-INF下的index.jsp页面是一个登陆表单所有代码如下

LoginAction代码如下:

package cn.wxz.Login;import com.opensymphony.xwork2.ActionSupport;public class LoginAction extends ActionSupport {private String name;private String password;public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public String login(){if(getName().equals("wxz")&&getPassword().equals("123")){return "success";}return "error";}}

index.jsp代码如下:

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><%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>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"><!--<link rel="stylesheet" type="text/css" href="styles.css">-->  </head>    <body><form action="test_login.action" method="post"> 用户名:<input type="text" name="name"/><br>密    码:<input type="password" name="password"><br><input type="submit" value="提交"><input type="reset" value="重置"></form>  </body></html>

success.jsp代码和error.jsp代码一样只是把登陆成功换成登陆失败success.jsp如下

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><%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>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"><!--<link rel="stylesheet" type="text/css" href="styles.css">-->  </head>    <body>登陆 成功  </body></html>

运行这个项目如图：

用户名输入wxz密码输入123可看到登陆成功，则搭建环境成功
