最近在学习struts2.3 跑的hello word

需要导入的jar包


commons-fileupload-1.2.2.jar

commons-io-2.0.1.jar

commons-lang3-3.1.jar

freemarker-2.3.18.jar

javassist-3.11.0.GA.jar

ognl-3.0.3.jar

struts2-core-2.3.1.jar

xwork-core-2.3.1.jar

struts.xml


<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
	"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

    <constant name="struts.devMode" value="true" />

    <package name="default" namespace="/" extends="struts-default">
        <action name="hi">
            <result>
                /hello.jsp
            </result>
        </action>
    </package>

    <!-- Add packages here -->

</struts>

web.xml


<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <display-name></display-name>	
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>

   <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>

最后我们可以index.jsp改名为hello.jsp
修改body里面的内容

  <body>
    Hello Struts2.3. <br>
  </body>

浏览界面如下
