我正在尝试使用maven在Spring MVC中进行文件上传的简单示例,然后我将阅读本教程.

但是我收到了这个错误

java.lang.NoClassDefFoundError: org/apache/commons/fileupload/FileItemFactory

我还在pom.xml中包含了依赖项

<!-- Apache Commons Upload --> 
<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
    <version>1.3.2</version>
</dependency>

也在dispatcher-servlet.xml中

<!-- Configure the multipart resolver -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <!-- one of the properties available; the maximum file size in bytes -->
    <property name="maxUploadSize" value="100000"/>
</bean> 

所以,你能帮我解决我的错误吗？

提前致谢.

我对这一小段代码有疑问

SimpleDateFormat sf = new SimpleDateFormat("yyyy-mm-dd HH:mm:ss");

String str = "2010-03-13 01:01:22";

Date date = sf.parse(str);

SimpleDateFormat f = new SimpleDateFormat("d MMM yyyy hh:mm aaa");

System.out.println(" Date " + f.format(date));   

输出:

 Date 13 Jan 2010 01:01 AM

代码似乎很好,但我仍然得到月份名称错误.请帮忙 !!谢谢.

我有一个简单的表单,可以选择上传图片,但上传文件,我没有使用此方法

<form:input path="logoData" id="image" type="file" />

相反,我使用的是ajax upload jquery pulgin.问题是upload.parseRequest(request)在下面的代码中返回null:

@RequestMapping(value = "/upload.htm", method = RequestMethod.POST)
public @ResponseBody String upload(HttpServletRequest request) throws FileUploadException{

    // Create a factory for disk-based file items
    FileItemFactory factory = new DiskFileItemFactory();

    // Create a new file upload handler
    ServletFileUpload upload = new ServletFileUpload(factory);

    // Parse the request
    List<FileItem> items = upload.parseRequest(request);
     System.out.println("====ITEMS====" + items.size());


     System.out.println("----REQUEST---" +request.getParameter("uploadImg"));
        System.out.println("-----SIZE----" +request.getParameterMap().size());
        Map<String, String> map = request.getParameterMap();

        for(Map.Entry<String, String> entry : map.entrySet()){
            System.out.println("----KEY---" + entry.getKey() + "----value---" …
