        <filter-class>org.apache.struts2.dispatcher.ActionContextCleanUp</filter-class>
    </filter>

	<filter-mapping>
        <filter-name>struts-cleanup</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>
	-->


    <filter>
         <filter-name>struts-prepare</filter-name>
         <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareFilter</filter-class>
    </filter>
    <filter-mapping>

        <filter-name>struts</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>

3- 修改struts.xml文件

interceptor-ref 的属性中，-修改成对应的大写字母。
比如<interceptor-ref name="servlet-config" /> 修改成 <interceptor-ref name="servletConfig" />
原来为：
<interceptor-ref name="exception" />
				<interceptor-ref name="alias" />
				<interceptor-ref name="servlet-config" />
				<interceptor-ref name="prepare" />
				<interceptor-ref name="i18n" />
				<interceptor-ref name="chain" />
				<interceptor-ref name="debugging" />
				<interceptor-ref name="profiling" />
				<interceptor-ref name="scoped-model-driven" />
				<interceptor-ref name="model-driven" />
				<interceptor-ref name="fileUpload" />
				<interceptor-ref name="checkbox" />
				<interceptor-ref name="static-params" />
				<interceptor-ref name="params">

修改后为：
<interceptor-ref name="exception" />
				<interceptor-ref name="alias" />
				<interceptor-ref name="servletConfig" />
				<interceptor-ref name="prepare" />
				<interceptor-ref name="i18n" />
				<interceptor-ref name="chain" />
				<interceptor-ref name="debugging" />
				<interceptor-ref name="profiling" />
				<interceptor-ref name="scopedModelDriven" />
				<interceptor-ref name="modelDriven" />
				<interceptor-ref name="fileUpload" />
				<interceptor-ref name="checkbox" />
				<interceptor-ref name="staticParams" />
				<interceptor-ref name="params">

4- 修改jsp文件标签

required="false"  替换为 requiredLabel="false"

5- 替换依赖的文件

以下java文件 依赖 com.opensymphony.xwork2.util.TypeConversionException
DateMinuteConverter.java
DateConverter.java
进行修改 去依赖 重新编译
