org.apache.commons.fileupload.FileUploadException：請求被拒絕，因爲沒有找到多部分邊界

Question

我想上傳文件並將其發佈到我的服務器以獲取響應。

在模板中我用類似的東西：

<form name="myForm" enctype="multipart/form-data"> 
     <input type="file" ngf-select ng-model="picFile" name="file" accept="image/*" required> 
     <button class="btn btn-primary" type="submit" ng-click="upload(picFile)" ng-disabled="!myForm.$valid">Ajouter 
    </form> 

這是我的角度控制器和服務：

$scope.upload = function (files) { 
       if (files && files.length) { 
        var file = files[0]; 
        BiAddDocFromExternalSourceService.uploadFile(file); 
     } 
} 
// Service: 
service.uploadFile = function (file) { 
      var fd= new FormData(); 
      fd.append('file', file); 
      return $http.post('ws/bdocument/add_external_document', fd, { 
       transformRequest: angular.identity, 
       headers: { 
        'Content-Type': 'undefined' 
       } 
      }); 
     }; 

而在服務器端，我developped一個REST服務這樣的：

@RequestMapping(value = "/add_external_document", method = RequestMethod.POST) 
public byte[] retrieveBDocumentThumbnail(@RequestParam MultipartFile file) 
     throws AbstractBdocInteractiveException { 
//do something.... 
    return something; 
} 

這是發送到服務器的請求，如果put **'Content-Type'：'undefined'** ：

，它看起來像如果我把

特林這一點，會引發以下異常：

org.springframework.web.multipart.MultipartException: The current request is not a multipart request

org.apache.commons.fileupload.FileUploadException: the request was rejected because no multipart boundary was found

Answer 1

你需要把它添加到你的Spring bean配置文件：

<bean id="multipartResolver" 
    class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> 
</bean> 

An d將其添加到pom.xml設置您想要的版本。

<dependency> 
    <groupId>commons-fileupload</groupId> 
    <artifactId>commons-fileupload</artifactId> 
    <version>1.3.1</version> 
</dependency> 

此外，編輯您的JS服務：

service.uploadFile = function (file) { 
      var fd= new FormData(); 
      fd.append('file', file); 
      return $http.post('ws/bdocument/add_external_document', fd, { 
       transformRequest: angular.identity, 
       headers: { 
        {'Content-Type': undefined} 
        // try with: 
        // {'Content-Type': 'multipart/form-data'} 
        // as well. 
       } 
      }); 
     }; 

你需要讓你的要求多，現在它是 「不確定」。
