上传文件弹簧引导和角度

Question

谁能帮我解决这个问题？

org.apache.tomcat.util.http.fileupload.FileUploadException:请求被拒绝，因为没有找到多部分边界，

FileController.java

package com.example.fileUploadApi.controller;
import org.apache.cxf.jaxrs.ext.multipart.MultipartBody;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@RestController
@RequestMapping(path = "/fileUpload")
@CrossOrigin(origins = "http://localhost:4200")
@Produces(MediaType.APPLICATION_JSON)
public class FileController 
{
    @POST
    @Path("/upload")
    public  void uploadData(MultipartBody file) throws Exception {
        System.out.println(file);
    }
}

upload-file.component.html

<div>
   <input type="file" change="uploadFile($event)"  />
</div>

UploadFileComponent.ts

uploadFile(event) {
file = event.target.files[0]
  const formData = new FormData();
  const dali = {
       a: 'dali'
   };
  formData.append('file', file);
  formData.append('model', JSON.stringify(dali));
  this.fileUploadService.upload(formData).subscribe(
    rsp => {console.log(rsp.type);}
}

将formData作为服务中的“params”传递给您，并使用@RequestParams在API中获取它。我在邮政电话里没看到@RequestParams。
