Java 文件上载时出现angularJS 405错误

我想用angularJS和RESTAPI上传文件，我使用以下代码 但我得到了405个错误：“方法不允许” 和异常：“org.springframework.web.HttpRequestMethodNotSupportedException”

这就是实体

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;

@Column(name = "file_name")
private String name;

@Column(name = "file")
private byte[] file;

 // getter and setter

这是Rest控制器

 @RequestMapping(value="/newDocument", headers = "'Content-Type': undefined ",   
    method = RequestMethod.POST)
    public void UploadFile(MultipartHttpServletRequest request
         ,HttpServletResponse response) {
        Iterator<String> itr=request.getFileNames();
        MultipartFile file=request.getFile(itr.next());
        String fileName=file.getOriginalFilename();
        System.out.println(fileName);
    }

从

RequestMapping

中删除

headers=“'Content-Type'：undefined”

。正如您在发布的标题中所看到的，它被设置为

多部分/表单数据

，我认为它应该是这样的。从angular中删除设置，我认为将其设置为undefined不会有任何作用
