file-upload - 如何防止 HTTP Rest Jboss resteasy Fileupload 因 'Could not find message body reader' 错误而失败？

Question

我有需求写一个REST服务来支持文件上传；我正在使用 JBOSS/Resteasy/Jersey，如下所示:

服务器 HTTP REST 处理程序:

@Path("document")
@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.TEXT_PLAIN)
public Response uploadFile(@FormDataParam("file") InputStream fileInputStream,
                           @FormDataParam("file") FormDataContentDisposition contentDispositionHeader,
                           @FormDataParam("selectedName") String selectedName,
                           @FormDataParam("name") String name,
                           @FormDataParam("notes") String notes) {
   String documentId;
   // upload the file
   String filePath = SERVER_UPLOAD_LOCATION_FOLDER + contentDispositionHeader.getFileName();
   try { fileUpload(fileInputStream, filePath); 
   }
   catch (IOException e) { throw new ApplicationRuntimeException( "Unable to upload file: " + selectedName); 
   }
   // create the document record
   documentId = create(selectedName, name, notes);
   return Response.ok("123456789").build();
}

单元测试

为了测试服务，我编写了以下单元测试:

@Test
public void testCreateDocument() throws Exception {
    Assert.assertNotNull(file);  
    Assert.assertTrue(file.canRead());
    given()
    .multiPart("notes", "my notes") .multiPart("selectedName", "selectedName")    
    .multiPart("name", "test.txt") .multiPart("file",file) 
    .contentType(MediaType.APPLICATION_OCTET_STREAM) .expect().body(equalTo("This is an uploaded test file."))
    .when().post(DOCUMENT_URL);
}

单元测试失败。以下是单元测试收到的错误消息以及服务器日志

单元测试错误信息

The server refused this request because the request entity is in a format not supported by the requested resource for the requested method.

另外，在发出上述单元测试时，会记录以下服务器日志:

我搜索了所有关于Could not find message body reader for type: class com.sun.jersey.core.header.FormDataContentDisposition of content type: multipart/form-data 错误但是找不到任何有用的东西。

我遇到了同样的问题，为了解决这个问题，我使用了 volkerbenders repository 中描述的解决方案.这是对我有用的解决方案:

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jaxrs</artifactId>
    <version>3.0.11.Final</version>
    <scope>provided</scope>

    private String getFileName(MultivaluedMap<String, String> headers) {
