Spring MVC 多部分文件 - NoSuchMethodError答案

【问题描述】：

我正在尝试使用 Spring 3 MVC 上传一些文件，但我总是遇到同样的异常：

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 org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:716)
at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:644)
at org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:560)
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。

这是我的控制器：

@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;
}


}

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

【问题讨论】：

您认为您可以运行mvn dependency:tree 命令并发布结果。这将更容易确定是否存在 commons-fileupload 的冲突版本
看起来像是一些不兼容的公共文件上传版本
java.lang.NoSuchMethodError 是版本不匹配的典型案例。检查maven中的依赖树可能会得到一个清晰的图片
我查过了。没有冲突。

标签： spring file tomcat tomcat7 nosuchmethoderror

【解决方案1】：

我发现问题出在哪里。当 maven 为部署构建目标路径时，它不会删除旧的库，但只会添加最新的库，所以当我解决了所有冲突（我更改了版本）时，Maven 使用新库的版本添加新的 jar 文件。我删除了不需要的文件，一切正常。

那些文件在 WEB-INF\target\lib 目录中。
