springMVC 文件上传被Cleaning up multipart file

springMVC 文件上传被Cleaning up multipart file10

我配置了:

	<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
		<property name="maxUploadSize">
			<value>10000</value>
		</property>
	</bean>

写了一个上传文件用的jsp:

<form action="<%=request.getContextPath()%>/Student/register.do" method="POST" enctype="multipart/form-data">  
    公钥文件: <input type="file" name="file"/><br/>  
    <input type="submit" value="提交公钥"/>  
</form>

处理用的Controller:(do后缀在配置文件中配了)

	@RequestMapping(value = "/Student/register", method = RequestMethod.POST)
	public String registerStudent(@RequestParam("file") MultipartFile file,HttpServletRequest request){
		String path = request.getSession().getServletContext().getRealPath("/WEB-INF/upload");
		//System.out.println(path);
		//System.out.println(file.getOriginalFilename());
		try {
			byte[] bytes = file.getBytes();
			FileOutputStream fos = new FileOutputStream(path+"/"+file.getOriginalFilename());
			fos.write(bytes);
			fos.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
		return "index";
	}

每次提交文件后,页面是跳转到index.jsp了,但是文件没有保存,后台信息:

[org.springframework.web.multipart.commons.CommonsMultipartResolver]Cleaning up multipart file [file] with original filename [pom.xml], stored in memory

请问这是什么错误?

问题补充：不好意思,是我弄错了,我应该去项目发布的路径下看文件上传没有,我一直在项目里看文件是否上传,所以弄错了,不要意思各位

你确定没传上？我刚才和你写了一样的代码，打出的是这个信息：

2013-05-08 11:42:08,176 DEBUG (org.springframework.web.multipart.commons.CommonsMultipartResolver:259) - Found multipart file [file] of size 2497 bytes with original filename [javax.inject-1.jar], stored in memory

不过我的文件上传了
