这个bug是由Struts2上传文件后return SUCCESS后报的错误： java.lang.AbstractMethodError: be.telio.mediastore.ui.upload.GarryMultiPartRequest.cleanUp()V at org.apache.struts2.dispatcher.multipart.MultiPartRequestWrapper.cleanUp(MultiPartRequestWrapper.java:271) at org.apache.struts2.dispatcher.Dispatcher.cleanUpRequest(Dispatcher.java:837) at org.apache.struts2.dispatcher.ng.PrepareOperations.cleanupRequest(PrepareOperations.java:103) at org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter.doFilter(StrutsPrepareAndExecuteFilter.j ava:103) 可以完美解决此类struts2的出错问题！
