struts2 2.5.13配置问题

2.5.13是今年9月份刚出的新版本，配置和之前的版本不太一样。（天坑……）

直奔主题：

一、首先，web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
  <display-name>Add</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
   <filter>
        <filter-name>struts-prepare</filter-name>
        <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareFilter</filter-class>
    </filter>

    <filter>
        <filter-name>struts-execute</filter-name>
        <filter-class>org.apache.struts2.dispatcher.filter.StrutsExecuteFilter</filter-class>
    </filter>


    <filter-mapping>
        <filter-name>struts-prepare</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>


    <filter-mapping>
        <filter-name>struts-execute</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

　　这和之前的：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
<display-name>HelloWorld</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.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>

　　是不一样的！！！

二、导包问题

    

三、struts.xml （放在src下）没变化

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
	"http://struts.apache.org/dtds/struts-2.5.dtd">
<struts>
	<package name="default" namespace="/" extends="struts-default">
	<action name="opadd" class="action.AddAction" method="executeAdd">
		<result name="+">/positive.jsp</result>
		<result name="-">/nagative.jsp</result>
	</action>	
	</package>
</struts>

　　over。
