前台使用

<form action="deploy" method="post" enctype="multipart/form-data"><input type="file" name="file" /><input type="submit" value="Submit" /></form>

上传文档，总是报

解决办法：

配置文件中增加：

<!-- 支持上传文件 --><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" />并引用<dependency><groupId>commons-io</groupId><artifactId>commons-io</artifactId><version>2.5</version></dependency><dependency><groupId>commons-fileupload</groupId><artifactId>commons-fileupload</artifactId><version>1.3.2</version></dependency>
