引用 3 楼 fangmingshijie 的回复:

看看你的struts配置文件

<constant name="struts.objectFactory" value="spring" /> 
	<constant name="struts.multipart.saveDir" value="/tmp"/>
	<!--开发模式下使用，这样可以打印出更详细的错误信息-->
	<constant name="sruts.devMode" value="true"/>
	<!--当struts的配置文件修改后，系统时候自动重新加载该文件，默认值为false（生产环境下使用）开发阶段最好打开-->
	<constant name="struts.configuration.xml.reload" value="true"/>
	<!--上传文件限制976M左右-->
	<constant name="struts.multipart.maxSize" value="1024288000"></constant>
	<constant name="struts.i18n.encoding" value="UTF-8" />
	<constant name="struts.action.extension" value="htm"></constant>
	
	<package name="struts-global" extends="struts-default,json-default">
		<interceptors>
			<interceptor name="exceptionInceptor" class="com.manage.exception.ExceptionMappingInterceptor"></interceptor>
		
			<interceptor-stack name="inceptorStack">
	            <interceptor-ref name="exceptionInceptor"></interceptor-ref>
				<interceptor-ref name="defaultStack"></interceptor-ref>
	        </interceptor-stack>
        
		</interceptors>
        
		<default-interceptor-ref name="inceptorStack"></default-interceptor-ref>
		
	
		<global-results>
			<result name="success" type="json">
				<param name="ignoreHierarchy">false</param>
				<param name="includeProperties">success,failureMsg,result.*</param>
			</result>
			
	    	<result name="error" type="json">
	    		<param name="ignoreHierarchy">false</param>
				<param name="includeProperties">success,actionErrors.*</param>
	    	</result>
	    	
	    	<result name="download_success" type="stream">
 				<param name="contentType">text/plain</param>
 				<param name="inputName">inputStream</param>
 				<param name="contentDisposition">attachment;filename="${downloadFileName}"</param>
       	 		<param name="bufferSize">20480</param>
 			</result>
		</global-results>

其他的继承struts-global
