2. web.xml

注意struts2版本,org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter 是2.5版本，和2.3版本不一致

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"

    </welcome-file-list>

3. struts.xml

http://localhost:8080/struts-sample/test/index

访问路径=<artifactId>struts-sample</artifactId> + <package name="test" > + <action name="index">

<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
        "http://struts.apache.org/dtds/struts-2.5.dtd">

<struts>
    <package name="test" extends="struts-default">

        <!-- If no class attribute is specified the framework will assume success and
        render the result index.jsp -->
        <!-- If no name value for the result node is specified the success value is the default -->
        <action name="index">
            <result>/index.jsp</result>
        </action>

        <!-- If the URL is hello.action then call the execute method of class HelloWorldAction.
        If the result returned by the execute method is success render the HelloWorld.jsp -->
        <action name="hello" class="Register" method="execute">
            <result name="success">/Helloworld.jsp</result>
        </action>
