spring cloud 中使用zuul作为路由时上传文件名称乱码处理

最近在做关于文件上传的接口，但是不管怎么处理，文件的名称总是乱码，我们使用的技术站为
spring cloud

  前端原代码：

 uploadData () {
        let formData = new FormData()
        let fileNames = []
        for (let i = 0; i < this.fileList.length; i++) {
          formData.append('files', this.fileList[i]);
          fileNames.push(this.fileList[i].name)
        }
        let json = {
          'description': this.sampleDescription,
          'status': this.qualifyValue
        }
        formData.append('json', JSON.stringify(json));
        // 上传文件
        this.$http.post(`/modules/api/v1/sampleInformation/uploadSampleReport/${this.$route.params.sampleId}`, formData).then(res => {
          if (res.status === 200) {
            this.$router.replace({
              name: 'my-sample'
            })
          } else {
            this.loading = false
          }
        })

更改后的代码：

 

 uploadData () {
        let formData = new FormData()
        let fileNames = []
        for (let i = 0; i < this.fileList.length; i++) {
          formData.append('files', this.fileList[i]);
          fileNames.push(this.fileList[i].name)
        }
        let json = {
          'description': this.sampleDescription,
          'status': this.qualifyValue
        }
        formData.append('json', JSON.stringify(json));
        // 上传文件
        this.$http.post(`/zuul/modules/api/v1/sampleInformation/uploadSampleReport/${this.$route.params.sampleId}`, formData).then(res => {
          if (res.status === 200) {
            this.$router.replace({
              name: 'my-sample'
            })
          } else {
            this.loading = false
          }
        })

后台处理代码：
  

List<Part> list = (List<Part>) request.getParts();
            for (Part part : list) {
                if (!part.getName().equalsIgnoreCase("files")) {
                    continue;
                }
                //Content-Disposition: form-data; name="files"; filename="test.pdf"
                String fileName = part.getHeader("Content-Disposition").split(";")[2];
                LOG.info("上传检测报告获取到的文件名称：{}", fileName);
                fileName = new String(fileName.getBytes(Charsets.ISO_8859_1), "UTF-8");
   }
