Struts2.1和Struts2.0的改变

2.1.*

<display-name>struts2 configuration</display-name>
	<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>

 

 

 

 

在Struts2.0.*中，在Web.xml中做如下配置便可加载Struts2.0.*

<!-- struts -->
	<filter>
		<filter-name>struts2</filter-name>
		<filter-class>
			org.apache.struts2.dispatcher.FilterDispatcher
		</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>*.action</url-pattern>
		<url-pattern>*.jsp</url-pattern>
	</filter-mapping>

	<!-- struts file upload -->
	<filter>
		<filter-name>struts-cleanup</filter-name>
		<filter-class>
			org.apache.struts2.dispatcher.ActionContextCleanUp
		</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>struts-cleanup</filter-name>
		<url-pattern>*.action</url-pattern>
	</filter-mapping>

 在Struts2.1.*中用StrutsPrepareFilter、StrutsExecuteFilter来取代FilterDispatcher、ActionContextCleanUp

因此，在web.xml中配置如下 代码，便可 加载应用：

    <filter>
        <filter-name>struts-prepare</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareFilter</filter-class>
        <init-param>
        	<param-name>actionPackages</param-name>
        	<param-value>org.apache.struts2.showcase.person</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>struts-prepare</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>


    <filter>
        <filter-name>struts-execute</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts-execute</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

 而且Struts2.1.*中可以用StrutsPrepareAndExecuteFilter整合了StrutsExecuteFilter、StrutsPrepareFilter两个过滤器，因此，便可做如下配置：

	<display-name>struts2 configuration</display-name>
	<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>*.action</url-pattern>
		<url-pattern>*.jsp</url-pattern>
	</filter-mapping>
