java.lang.IllegalStateException: File has been moved - cannot be read again

在用jqueryfileupload上传文件时报如下错误：

java.lang.IllegalStateException: File has been moved - cannot be read again

后台接口是spring mvc, 检查sprnig mvc配置文件：

<!-- 上传文件拦截，设置最大上传文件大小   10M=10*1024*1024(B)=10485760 bytes --><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><property name="maxUploadSize" value="10240000" /></bean>

配置了允许上传文件的最大size, 而自己上传的文件大小远远小于这个，什么情况呢？

经过网上搜索资料，发现spring mvc除了maxUploadSize参数，还有一个maxInMemorySize参数，指定允许文件被写入内存的最大szie，则默认为1024字节，即1MB，如果试上传大于1024个字节的文件，你需要增加maxInMemorySize价。

<!-- 上传文件拦截，设置最大上传文件大小   10M=10*1024*1024(B)=10485760 bytes --><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><property name="maxUploadSize" value="${web.maxUploadSize}" /><property name="maxInMemorySize">              <value>10240000</value>          </property></bean>

spring-mvc.xml配置如下：
