struts2文件下载点击取消报错的解决方法
以前在用struts2做下载功能的时候，点击下载，弹出下载对话框，再点击取消时，一般会报错，但不影响。所有也没去注意。今天重新做这个功能的时候，又遇到这个异常2011-2-11 15:35:05 org.apache.catalina.core.StandardWrapperValve invoke
严重: Servlet.service() for servlet default threw exceptionjava.lang.IllegalStateExceptionat org.apache.catalina.connector.ResponseFacade.sendError(ResponseFacade.java:407)at org.apache.struts2.dispatcher.Dispatcher.sendError(Dispatcher.java:725)at org.apache.struts2.dispatcher.Dispatcher.serviceAction(Dispatcher.java:485)at org.apache.struts2.dispatcher.ng.ExecuteOperations.executeAction(ExecuteOperations.java:77)at org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter.doFilter(StrutsPrepareAndExecuteFilter.java:76)at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235)at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206)at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233)at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191)at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128)at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109)at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286)at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:845)at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583)at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447)at java.lang.Thread.run(Thread.java:619)
解决方法：参考网上的，经测试解决了。
struts.xml里的package标签里加<global-results><result name="client-abort-exception">/ignored.jsp</result><!-- 全局 --></global-results>在Action标签里加<exception-mapping result="client-abort-exception" exception="org.apache.catalina.connector.ClientAbortException"></exception-mapping><!-- 抓异常 --><result name="success" type="stream">....</result>再新建一个ignored.jsp里面什么都不用写
