第一個Struts2例子

 1.新建一個Struts2工程

 

2.修改工程的編碼utf-8

 

3.導入struts-2.3.1.2\apps\struts2-blank\WEB-INF\lib目錄下所有的jar包

 

4.創建一個test.jsp

      測試struts,輸出有命名空間的的helloWorldAction:

      <a href="${pageContext.request.contextPath}/base/helloWorldAction.action">測試</a>

      

5.創建一個success.jsp

      測試成功

     

6.創建一個HelloWorldAction

        public class HelloWorldAction{

             public String execute(){

                  ....

                  return SUCCESS;  

             }

        }

7.配置struts.xml文件

        <package name="helloworld" namespace="base" extends="struts-default.xml">

            <action name="helloWorldAction" class="...HelloWorldAction">

                <result>success.jsp</result>

            </action>

       </package>

8.配置web.xml文件

       <filter>

              <filter-name>StrutsPrepareAndExecuteFilter</filter-name>

              <filter-class>org.apache.struts2.dispatcher.ng.filter.

                              StrutsPrepareAndExecuteFilter</filter-class>

      </filter>

      <filter-mapping>

              <filter-name>StrutsPrepareAndExecuteFilter</filter-name>
