Spring Boot + Multipart 文件上传产生格式错误的多部分请求

Question

我目前正在使用 Spring Boot v1.3.0.BUILD-SNAPSHOT 和 Spring v4.2.2.BUILD-SNAPSHOT。

如果我尝试执行多文件上传(通过 angular):

myService.upload = function(name ,content) {
    var fd = new FormData();
    fd.append('name', name);
    fd.append('file', content);   

    return $http({
      method: 'POST',
      url: SERVER_BASE_URL + 'upload',
      data: fd,
      transformRequest: angular.identity,
      headers: {
        'Content-Type': 'multipart/form-data'
      }}).then(function(res) {       
        return res.headers('Location');
      }, function(reason) {
          throw reason;
      });
};

我收到错误:

我添加了一个多部分解析器 bean:

@Bean
public FilterRegistrationBean openEntityManagerFilterRegistrationBean() {
    // Set upload filter
    final MultipartFilter multipartFilter = new MultipartFilter();
    final FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(multipartFilter);
    filterRegistrationBean.addInitParameter("multipartResolverBeanName", "commonsMultipartResolver");

    return filterRegistrationBean;
}

@Bean
public CommonsMultipartResolver commonsMultipartResolver() {
    final CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver();
    commonsMultipartResolver.setMaxUploadSize(-1);

    return commonsMultipartResolver;
}

然而，hiddenHttpMethodFilter 似乎在我的多部分解析器之前仍然被调用:

[DEBUG] org.eclipse.jetty.servlet.ServletHandler - call filter characterEncodingFilter [DEBUG] org.eclipse.jetty.servlet.ServletHandler - call filter hiddenHttpMethodFilter [WARN] org.eclipse.jetty.util.MultiPartInputStreamParser - Badly formatted multipart request

我尝试将 @Order(0) 添加到我的 Bean 中，但这没有效果。

我还缺少什么？

Answer 1

我不使用过滤器上传文件。

在此处尝试这种方法:

// in configs
  @Bean
     Public MultipartConfigElement multipartConfigElement () {
         End MultipartConfigFactory factory = new MultipartConfigFactory ();
         Factory.setMaxFileSize ( "50MB");
         Factory.setMaxRequestSize ( "50MB");
         Return factory.createMultipartConfig ();
     }

和

        // in controller
         @RequestMapping (value = "/ sendfile", method = RequestMethod.POST)
         Public ModelAndView formSubmit (@RequestParam ( "file") MultipartFile file) {

         }

注意:请记住删除您在配置中放置的过滤器

我希望有所帮助
