Spring MVC 多部分文件 - NoSuchMethodError

Question

我正在尝试使用 Spring 3 MVC 上传一些文件，但我总是遇到相同的异常:

java.lang.NoSuchMethodError: org.apache.commons.fileupload.servlet.ServletFileUpload.parseRequest(Lorg/apache/commons/fileupload/RequestContext;)Ljava/util/List;
at org.apache.commons.fileupload.servlet.ServletFileUpload.parseRequest(ServletFileUpload.java:116)
at org.springframework.web.multipart.commons.CommonsMultipartResolver.parseRequest(CommonsMultipartResolver.java:155)
at org.springframework.web.multipart.commons.CommonsMultipartResolver.resolveMultipart(CommonsMultipartResolver.java:138)
at org.springframework.web.servlet.DispatcherServlet.checkMultipart(DispatcherServlet.java:904)
at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:747)

at javax.servlet.http.HttpServlet.service(HttpServlet.java:647)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:728)

我在依赖项中找到了这个方法:ServletFileUpload.parseRequest，所以它存在。我读到可能有一些其他库，例如在 Tomcat 的 lib 文件夹中，但我找不到任何东西。

这是我的 Controller :

@Controller
@RequestMapping("/file")
public class FilesController {


@Autowired
EventFileUploadValidator eventValidator;

@Autowired
Configuration config;

@InitBinder("fileupload")
public void initEventFileBinde(WebDataBinder bind){
    bind.setValidator(eventValidator);
}

@RequestMapping(value = "/addEventFile", method= RequestMethod.POST)
public String uploadEventFile(@ModelAttribute("fileupload") FileUploadModel file, BindingResult results, HttpServletRequest request, HttpServletResponse response,  Model model, HttpSession session) throws IOException, NoConfigurationFoundException{

    if(!results.hasErrors()){
        MultipartFile uplodadFile = file.getFile();
        if(uplodadFile != null){

           // String path = config.getProperty("upload_file_directory").toString();
           // String filename = uplodadFile.getName();
           // uplodadFile.transferTo(new File(path+"/"+filename));

        }
    }

    return ViewHelper.EventsListView;
}


}

我不知道该怎么做...我在 Windows 上使用 Tomcat 7.0.42

Answer 1

我已经找到问题所在了。当 Maven 正在构建用于部署的目标路径时，它不会删除旧库，但只会添加最新库，因此当我解决了所有冲突(我更改了版本)后，Maven 添加了带有新库版本的新 jar 文件。我删除了不需要的文件，一切正常。

这些文件在 WEB-INF\target\lib 目录中。
