我将SpringMVC与java配置一起使用，并定义了一些rest服务。我使用Spring作为服务器后端，AngularJS作为WebFrontend

我想从我的AngularJS站点上传一两个CSV文件到我的rest服务。我必须如何用java配置配置spring才能工作？我使用了Tomcat和Servlet3容器

我的上载rest服务如下所示：

@Controller
@RequestMapping("Upload")
@MultipartConfig(fileSizeThreshold=1024*1024*10,    // 10 MB
maxFileSize=1024*1024*50,          // 50 MB
maxRequestSize=1024*1024*100)      // 100 MB
public class UploadController {

    @RequestMapping(value="/upload", method=RequestMethod.GET)
    public @ResponseBody String provideUploadInfo() {
        return "You can upload a file by posting to this same URL.";
    }

    @RequestMapping(value="/upload", method=RequestMethod.POST)
    public @ResponseBody String handleFileUpload(@RequestParam("name") String name, 
            @RequestParam("file") MultipartFile file){
        if (!file.isEmpty()) {
            try {
                byte[] bytes = file.getBytes();
                BufferedOutputStream stream = 
                        new BufferedOutputStream(new FileOutputStream(new File(name + "-uploaded")));
                stream.write(bytes);
                stream.close();
                return "You successfully uploaded " + name + " into " + name + "-uploaded !";
            } catch (Exception e) {
                return "You failed to upload " + name + " => " + e.getMessage();
            }
        } else {
            return "You failed to upload " + name + " because the file was empty.";
        }
    }

}

public class WebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[]{ PersistenceContext.class,AppConfig.class,SecurityConfig.class }; 
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[] { WebConfig.class };
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/Spring/*" }; 
    }

    @Override
    protected Filter[] getServletFilters() {

        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("UTF-8");

        CorsFilter cf=new CorsFilter();
            MultipartFilter mpf=new MultipartFilter(); //MultipartFilter support
        return new Filter[] {characterEncodingFilter,cf,mpf};

我需要“StandardServletMultipartResolver”吗？或者其他什么让上传工作？如果是这样，我如何使用java配置启用多部分上传？我目前的配置如下所示：

@Controller
@RequestMapping("Upload")
@MultipartConfig(fileSizeThreshold=1024*1024*10,    // 10 MB
maxFileSize=1024*1024*50,          // 50 MB
maxRequestSize=1024*1024*100)      // 100 MB
public class UploadController {

    @RequestMapping(value="/upload", method=RequestMethod.GET)
    public @ResponseBody String provideUploadInfo() {
        return "You can upload a file by posting to this same URL.";
    }

    @RequestMapping(value="/upload", method=RequestMethod.POST)
    public @ResponseBody String handleFileUpload(@RequestParam("name") String name, 
            @RequestParam("file") MultipartFile file){
        if (!file.isEmpty()) {
            try {
                byte[] bytes = file.getBytes();
                BufferedOutputStream stream = 
                        new BufferedOutputStream(new FileOutputStream(new File(name + "-uploaded")));
                stream.write(bytes);
                stream.close();
                return "You successfully uploaded " + name + " into " + name + "-uploaded !";
            } catch (Exception e) {
                return "You failed to upload " + name + " => " + e.getMessage();
            }
        } else {
            return "You failed to upload " + name + " because the file was empty.";
        }
    }

}

public class WebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[]{ PersistenceContext.class,AppConfig.class,SecurityConfig.class }; 
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[] { WebConfig.class };
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/Spring/*" }; 
    }

    @Override
    protected Filter[] getServletFilters() {

        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("UTF-8");

        CorsFilter cf=new CorsFilter();
            MultipartFilter mpf=new MultipartFilter(); //MultipartFilter support
        return new Filter[] {characterEncodingFilter,cf,mpf};

    }




}

和应用程序配置

@Configuration
public class AppConfig {

    @Bean
    public Test getTest(){


        return new Test();
    }
}

上传的例子来自这个站点，但他们使用了MultiPartConfigFactory，这是从SpringBoot；我能用这个来做手术吗？我当时没有用弹簧靴。。那么，使用我的配置实现多部分上传的最简单方法是什么呢

EDIT2：我在配置中添加了两个新的getServletFilter，现在看起来像这样，我添加了一个MultipartFilter（）：

在我的网络配置中，我添加了一个标准ServletMultipartResolver：

@Bean
public MultipartResolver multipartResolver(){

        return new StandardServletMultipartResolver();
    }

现在我想用一个简单的html站点来测试它，如下所示：

@Controller
@RequestMapping("Upload")
@MultipartConfig(fileSizeThreshold=1024*1024*10,    // 10 MB
maxFileSize=1024*1024*50,          // 50 MB
maxRequestSize=1024*1024*100)      // 100 MB
public class UploadController {

    @RequestMapping(value="/upload", method=RequestMethod.GET)
    public @ResponseBody String provideUploadInfo() {
        return "You can upload a file by posting to this same URL.";
    }

    @RequestMapping(value="/upload", method=RequestMethod.POST)
    public @ResponseBody String handleFileUpload(@RequestParam("name") String name, 
            @RequestParam("file") MultipartFile file){
        if (!file.isEmpty()) {
            try {
                byte[] bytes = file.getBytes();
                BufferedOutputStream stream = 
                        new BufferedOutputStream(new FileOutputStream(new File(name + "-uploaded")));
                stream.write(bytes);
                stream.close();
                return "You successfully uploaded " + name + " into " + name + "-uploaded !";
            } catch (Exception e) {
                return "You failed to upload " + name + " => " + e.getMessage();
            }
        } else {
            return "You failed to upload " + name + " because the file was empty.";
        }
    }

}

public class WebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[]{ PersistenceContext.class,AppConfig.class,SecurityConfig.class }; 
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[] { WebConfig.class };
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/Spring/*" }; 
    }

    @Override
    protected Filter[] getServletFilters() {

        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("UTF-8");

        CorsFilter cf=new CorsFilter();
            MultipartFilter mpf=new MultipartFilter(); //MultipartFilter support
        return new Filter[] {characterEncodingFilter,cf,mpf};

    }

在此处插入标题
要上载的文件：
名称：

按此处上载文件！

但它表示“HTTP状态400-所需的字符串参数'name'不存在”。为什么名字不存在

如果您使用的是Servlet 3.0，则必须将dispatcher Servlet配置为支持多部分。我遇到了和你完全相同的问题。我配置了多部分解析器bean，但仍然遇到问题。只需将以下行添加到应用程序初始值设定项类（扩展

WebApplicationInitializer

）即可：

dispatcher

是

ServletRegistration.Dynamic

的一个实例。有关更多细节，请阅读我对问题的回答

我也遇到了同样的问题，结果证明这是由于StandardServletMultipartResolver造成的。将其更改为org.springframework.web.multipart.commons.commons多部分解析器

这可能与本文中提出的问题无关，但可能会有所帮助。启用调试后，我可以在日志中看到此调试消息：- 请求已经是MultipartTTpServletRequest-如果不在转发中，这通常是由web.xml中的额外MultipartFilter导致的

通过从

getServletFilters（）

中的过滤器数组中删除

MultipartFilter

来解决此问题。

MultipartFilter mpf=new MultipartFilter（）
检查@但这对我的配置没有帮助，我已经更新了我的第一篇帖子！！并添加了一个新的MultipartFilter和一个StandardServletMultipartResolver，对吗？但我还是犯了一个错误。。见我的第一篇帖子中的Edit2，我有完全相同的问题。你能修好它吗？
