为什么我什么都配置好了，就是接收不到来自multipart/form-data的<form>参数？
这是jsp：
<body>
<form action="/save" method="post" enctype="multipart/form-data">
<input type="file" name="file">
<input type="submit"/>
</form>
</body>这是springmvc配置文件:
<bean id="commonsMultipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="utf-8"></property>
<property name="maxUploadSize" value="10485760000"></property>
<property name="maxInMemorySize" value="40960"></property>
</bean>
<!-- 扫描路径 -->
<context:component-scan base-package="cn.liangjiateng.controller"/>
<context:component-scan base-package="cn.liangjiateng.service"/>
<mvc:annotation-driven/>
<!-- 视图层配置 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
id="internalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/WEB-INF/jsp/" />
<!-- 后缀 -->
<property name="suffix" value=".jsp" />
</bean>这是controller：
@RequestMapping(value = "/save",method = RequestMethod.POST)
public String save(@RequestParam("file") MultipartFile file, HttpServletRequest request){
System.out.println(file.getOriginalFilename());
return "upload";
}然后就报错：
求解，搞了好久

Have you imported this package?
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3.1</version>
</dependency>

<!-- SpringMVC上传文件时，需要配置MultipartResolver处理器 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- 指定所上传文件的总大小不能超过200000KB。注意maxUploadSize属性的限制不是针对单个文件，而是所有文件的容量之和 -->
<property name="maxUploadSize" value="200000000"/>
</bean>
Try adding this sentence to the spring configuration. I have not studied sping upload files in detail, but I happen to have this requirement in the projects I have worked on
Sorry I didn’t notice you added this sentence, so I may not be able to help you
