我终于找到了一个可以使用HandlerExceptionResolver的解决方案。
将多部分解析器添加到你的Spring配置中：
<bean id="multipartResolver" > <!-- the maximum size of an uploaded file in bytes --> <!-- <property name="maxUploadSize" value="10000000"/> --> <property name="maxUploadSize" value="1000"/></bean>
Mode-UploadedFile.java：
package com.mypkg.models;import org.springframework.web.multipart.commons.CommonsMultipartFile;public class UploadedFile{ private String title; private CommonsMultipartFile fileData; public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public CommonsMultipartFile getFileData() { return fileData; } public void setFileData(CommonsMultipartFile fileData) { this.fileData = fileData; }}View -/upload.jsp：
