35             </plugin>
36         </plugins>
37     </build>
38 </project>
  • 配置web.xml
 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 3     xmlns="http://java.sun.com/xml/ns/javaee"
 4     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

12         <welcome-file>default.htm</welcome-file>
13         <welcome-file>default.jsp</welcome-file>
14     </welcome-file-list>
15 
16     <filter>
17         <filter-name>struts2</filter-name>
18         <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
19     </filter>
20     <filter-mapping>
21         <filter-name>struts2</filter-name>
22         <url-pattern>/*</url-pattern>
23     </filter-mapping>
24 </web-app>
  • 编写action代码
 1 package com.xxxx.action;
 2 
 3 import com.opensymphony.xwork2.ActionSupport;
 4 
 5 public class TestAction extends ActionSupport {
 6 
 7     public String sayHello(){
 8         
 9         System.out.println(">>>>test Ok");
10         
11         return SUCCESS;
12     }
13 }
  • 配置struts.xml
 1 <?xml version="1.0" encoding="UTF-8"?>
 2         <!DOCTYPE struts PUBLIC
 3             "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
 4             "http://struts.apache.org/dtds/struts-2.5.dtd">
 5 <struts>
 6     <!-- 启用动态方法加载 -->
 7     <constant name="struts.enable.DynamicMethodInvocation" value="true" />

 8     <package name="hell" namespace ="/hello" extends="struts-default">
 9         <action name="test" class="com.xxxx.action.TestAction">
10             <result name="success">/Hello.jsp</result>
11         </action>
12     </package>
13 </struts>
  • 在URL访问
http://localhost:8080/Struts2Test0809/hello/test!sayHello
                     /项目名称/package_namespace/action_name!action_functionName
