在eclipse下配置struts

1. 下载struts包，地址：http://struts.apache.org/download.cgi#struts23163我下载的是Struts 2.3.30，如图:

2. 新建web工程，我建立的工程名为 MyTry ，不要忘了在最后finish前打钩，即添加web.xml。

3. 将struts-2.3.30文件夹下的lib文件里的jar添加到工程的lib文件夹下。然后将这些包buildpath。

4. 将struts-2.3.30文件夹下的apps文件里的struts2-blank包打开，找到struts.xml文件，将它复制到你新建的工程里，并对其进行修改，这是我修改后的struts.xml 文件：

<?xml version="1.0"encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD StrutsConfiguration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">
 
<struts>
 
    <constant name="struts.enable.DynamicMethodInvocation"value="false" />
    <constant name="struts.devMode" value="true" />
 
    <package name="default" namespace="/"extends="struts-default">
 
        <action name="HelloWorld" class="com.HelloWorld">
            <result name="success">/success.jsp</result>
            <result name="error">/error.jsp</result>
        </action>
      
    </package>
 
</struts>

5. 修改web.xml配置文件，添加过滤器：

<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>/*</url-pattern>
    </filter-mapping>

6. 新建HelloWorld类，如图：

添加相应的方法，代码如下：

 
package com;
 
import com.opensymphony.xwork2.ActionSupport;
 
public class HelloWorld extends ActionSupport {
 
    /**
     *
     */
    private static final long serialVersionUID = 1L;
    private String name;
   
    public String getName()
    {
       return name;
    }
   
    public void setName(String name)
    {
       this.name = name;
    }
   
    public String execute()
    {
      
       if(name.equals(""))
       return "error";
       else
           return "success";
    }
   
}

7. 新建 success.jsp , error.jsp, weicome.jsp。

success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!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=UTF-8">
<title>Insert title here</title>
</head>
<body>
<center>this is success!</center>
</body>
</html>

error.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!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=UTF-8">
<title>Insert title here</title>
</head>
<body>
<center>this is error!</center>
</body>
</html>
welcome.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!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=UTF-8">
<title>Insert title here</title>
</head>
<body>
<form action="HelloWorld.action" method="post">
<input type="text" name="name" >
<input type="submit" value="提交"/>

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

这样，程序就可以运行了。
