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：
@H_502_8@<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="maxUploadSize"> <value>102400000</value> </property> </bean>
经过网上搜索资料，发现spring mvc除maxUploadSize参数，还有1个maxInMemorySize参数，指定允许文件被写入内存的最大szie，则默许为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。
以下:
@H_502_8@<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans⑷.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context⑷.0.xsd"> <!-- 添加拦截器 --> <bean id="handlerMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"> <property name="interceptors"> <bean class="com.message.web.interceptor.SessionInterceptor" /> </property> </bean> <!-- 配置controller扫描 --> <context:component-scan base-package="com.message.web.controller" /> <!-- 配置springmvc视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass"> <value>org.springframework.web.servlet.view.JstlView</value> </property> <property name="prefix"> <value>/message/</value> </property> <property name="suffix"> <value>.jsp</value> </property> </bean> <!-- 设置上传文件的最大尺寸为100MB --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="maxUploadSize"> <value>102400000</value> </property> <property name="maxInMemorySize"> <value>10240000</value> </property> </bean> </beans>
