SpringMvc上傳文件拋出3次MaxUploadSizeExceededException 問題

SpringMvc 3.2.18 版本開發(fā)的文件上傳在Tomcat7 上運(yùn)行拋出了3個MaxUploadSizeExceededException 異常；
正常情況下 當(dāng)上傳文件大小超過允許的大小時SpirngMvc 會拋出一個MaxUploadSizeExceededException 異常 如下

但是當(dāng)SpringMvc3.2.18 在tomcat7中運(yùn)行時 就會拋出3個MaxUploadSizeExceededException； 切換到Tomcat6后 成功修復(fù)， 只拋出了一次；
