记一次让人恶心的springcloud文件上传问题

本来的写法：客户端

@ApiOperation(value = "融资申请上传文件存储")
@RequestMapping(path = "/b/v1/external/gateway/adapter/aws/object/save", method = RequestMethod.POST)
ResponseEntity objectSave(@ApiParam("融资申请文件") @RequestParam("file") MultipartFile file,
                                  @ApiParam("文件名") @RequestParam("fileName") String fileName,
                                  @ApiParam("客户号") @RequestParam("custCode") String custCode,
                                  @ApiParam("业务类型") @RequestParam("businessType") String businessType,
                                  @ApiParam("文件后缀") @RequestParam("fileType") String fileType,
                                  @ApiParam("上传时间") @RequestParam("uploadDate") String uploadDate);

然后各种报错，不列出了，搞了整整3天。直接帖正确写法

客户端：

@FeignClient(value = "bis-zyhy", configuration = FeignSupportConfig.class)
public interface BisZyhyCommonServiceInvoke {
@ApiOperation(value = "融资申请上传文件存储")
    @RequestMapping(path = "/b/v1/external/gateway/adapter/aws/object/save", method = RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
    ResponseEntity objectSave(@ApiParam("融资申请文件") @RequestPart("file") MultipartFile file,
                                      @ApiParam("文件名") @RequestParam("fileName") String fileName,
                                      @ApiParam("客户号") @RequestParam("custCode") String custCode,
                                      @ApiParam("业务类型") @RequestParam("businessType") String businessType,
                                      @ApiParam("文件后缀") @RequestParam("fileType") String fileType,
                                      @ApiParam("上传时间") @RequestParam("uploadDate") String uploadDate);

}

添加FeignSupportConfig

package cn.com.fero.configuration;

import feign.form.spring.SpringFormEncoder;
import org.springframework.beans.factory.ObjectFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.web.HttpMessageConverters;
import org.springframework.cloud.netflix.feign.support.SpringEncoder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;



@Configuration
public class FeignSupportConfig {


    @Autowired
    private ObjectFactory messageConverters;

    @Bean
    public SpringFormEncoder feignFormEncoder() {
        return new SpringFormEncoder(new SpringEncoder(messageConverters));
    }


}

添加依赖：

			io.github.openfeign.form
			feign-form
			3.3.0
		
		
			io.github.openfeign.form
			feign-form-spring
			3.3.0
		
		
			commons-fileupload
			commons-fileupload
			1.3.3
		

服务端也要改为@RequestPart

    @ApiOperation(value = "保存对象", notes = "")
    @RequestMapping(value = "object/save", method = RequetstMethod.POST)
    public JsonResponse objectSave(@RequestPart("file") MultipartFile file, @RequestParam String fileName,
                                   @RequestParam String custCode, @RequestParam String businessType, @RequestParam String fileType, @RequestParam String uploadDate) throws IOException {
        String objectKey = businessType + "/" + uploadDate + "_" + fileName;
        PutObjectResult result = AWSObjectSaveUtils.uploadFileInputStream(custCode, objectKey, file.getInputStream());
        Map resultMap = new HashMap();
        resultMap.put("serialNo", result.getETag());
        log.debug("外部接口-对象存储操作 保存对象 结束");
        return JsonResponse.newInstance().setMessage("success").setSuccess(true).setTimestamp(new Date()).setData(resultMap);
    }
