struts2簡單入門例子

1、建立javaWeb工程hello

2、在WebRoot>WEB-INF>lib下導入struts2的九個基本jar包，建立path

3、在WebRoot>WEB-INF下新建web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>
  <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>
</web-app>

4、在src>com.action包下新建TestAction.java

package com.action;

import com.opensymphony.xwork2.ActionSupport;
public class TestAction extends ActionSupport{
	public String execute() throws Exception{
		System.out.println("This is my StrutsTest Propram");
		return SUCCESS;
	}
}

5、在src下新建struts文件

<?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>		
	<package name="default" extends="struts-default">
		
		<action name="test" class="com.action.TestAction">
			<result>/index.jsp</result>
		</action>
		
	</package>
</struts>

6、在WebRoot下建立index.jsp文件

7、啓動Tomcat，在瀏覽器輸入http://localhost:8080/hello/test 或 http://localhost:8080/hello/test.action
