org.springframework.web.multipart.MultipartException：當前請求不是多部分請求 spring boot

Question

我正在嘗試將我的項目（spring boot）中的 excel 作為 multipartdata 上傳

如下

html

<div class="col-xs-12 col-sm-12 col-md-3 col-lg-3">

                                <label for="uploadDocumentMO" class="control-label">Upload Document:</label> 
                                <input type="file" class="filestyle" data-buttonName="btn btn-primary" ng-model="upload.documentMO" id="uploadDocumentMO" name="file" accept="application/xlsx"
                                    base-sixty-four-input>
                            </div>

這是我的 ajax 調用

  $("#uploadCorpUserDataBtn").on('click', function() {
        debugger

        var formData = new FormData();
        formData.append('file', $('input[type=file]')[0].files[0]);


            console.log(formData);
            console.log(token);
            $.blockUI({
                message: 'Please wait...',
                css: {
                    border: 'none',
                    backgroundColor: 'white'
                }
            });
            $http.post("http://localhost:8080/api/cmsexcelupload/bulk/corporate/excel/upload/" + username, formData, {
                method: "POST",
                headers: { 'token': token },
            }).then(function(response) {
                console.log(response);
                console.log(response.data.data);
                $scope.merchantData=response.data.data;
                alert("Merchants uploaded successfully");

                $scope.showMerchantData();
                $.unblockUI();
                $scope.userPan = "";
                $scope.upload=null;
            }
});

這是我的控制器

@PostMapping("/bulk/corporate/excel/upload/{username}") 
    public ResponseEntity<GeneralResponse> merchantbranchUpload( HttpServletRequest request,HttpServletResponse response, HttpSession httpSession, @RequestHeader("token") String token ,@RequestParam("file") MultipartFile multipartFile) throws IOException{

corporateExcelUploadLoger.info("Getting Excel from input stream");
        XSSFWorkbook workbook=new XSSFWorkbook(multipartFile.getInputStream());
        String pathTosaveExcelFile=filesUtil.getProperty("documentUploadPath");
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            String excelPath = "D:\\corporateUserExcel_"+dateFormat.format(new Date())+".xlsx";
    }

當我點擊服務器時，它給出以下異常

在 spring mvc 中，我們將添加支持，我們將在配置中添加多部分支持，但在 spring boot 中，我沒有找到任何要添加的配置。

如何添加多部分支持？

幫我解決這個問題，我對 Spring Boot 非常陌生。 謝謝你。

Answer 1

在請求頭中，您應該指定內容類型，因此您應該有一個名稱為Content-Type且值為： multipart/form-data; boundary=--------------------------362947062764690924037801的頭參數multipart/form-data; boundary=--------------------------362947062764690924037801 multipart/form-data; boundary=--------------------------362947062764690924037801 。

編輯：我認為您還需要在配置類中配置一個多部分解析器，首先在 POM 中添加這些依賴項：

<!-- multipart resolver-->
<dependency>
    <groupId>commons-fileupload</groupId>
    <artifactId>commons-fileupload</artifactId>
    <version>1.2.1</version>
</dependency>

<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
    <version>2.5</version>
</dependency>

並且您需要聲明此Bean配置：

@Bean(name = "multipartResolver")
public CommonsMultipartResolver multipartResolver() {
    CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
    return multipartResolver;
}
