Spring MultiPart MediaType不支持 [英] Spring MultiPart MediaType Unsupported

问题描述

我实际上正在尝试在Spring服务器上上传文件.事实是，我总是遇到415(不受支持的媒体类型)错误，而服务器的日志中却没有任何错误.

I'm actualy trying to upload a file on my Spring server. The fact is that I always have a 415 (Unsupported Media Type) error without any error in server's log.

有我的代码:

客户端:

  journal.import= function(id, file, callbackSuccess, callbackError){
        var fd = new FormData();
        fd.append('file', file);
        $http.post(config.API_URL +"/newspapper/import/"+id, fd, {
        transformRequest: angular.identity,
        headers: {'Content-Type': undefined}
        }).success(callbackSuccess).error(callbackError);
    }

服务器端:

@POST
@Path("/import/{id}")
@Override
public void importJournalTypeConcurrent(@PathParam("id") long id,
        @RequestParam("file") MultipartFile file) {
    System.out.println(file.getName());
}

为解决此问题，我还添加了MultipartResolver

To solve this problem, I've also add a MultipartResolver

@Bean
public CommonsMultipartResolver getMultipartResolver() {
    return new CommonsMultipartResolver();
}

这可能是愚蠢的，但我找不到我错过的东西.

It's probably something stupid, but I can't find what I missed.

推荐答案

要定义实现，请创建一个具有id的bean DispatcherServlet的应用程序上下文中的"multipartResolver"

To define an implementation, create a bean with the id "multipartResolver" in a DispatcherServlet's application context

声明CommonsMultipartResolver如下:

@Bean(name = "multipartResolver")
