web-services – Jersey客户端异常：找不到消息正文编写器

我正在使用Jersey客户端来访问 PHP

Web服务以获取图像上载功能.我收到以下异常：

Caused by: com.sun.jersey.api.client.ClientHandlerException: 
A message body writer for Java type, class 
com.sun.jersey.multipart.FormDataMultiPart, and MIME media type, 
multipart/form-data, was not found
    at com.sun.jersey.api.client.RequestWriter.writeRequestEntity(RequestWriter.java:288)
    at com.sun.jersey.client.urlconnection.URLConnectionClientHandler._invoke(URLConnectionClientHandler.java:204)
    at com.sun.jersey.client.urlconnection.URLConnectionClientHandler.handle(URLConnectionClientHandler.java:147)
    ... 63 more

这是我正在使用的代码：

WebResource webResource = Client.create().resource(HTTP_REST_URI);
JSONObject jSONObj = webResource.queryParams(queryParams)
      .type(MediaType.MULTIPART_FORM_DATA)
      .post(JSONObject.class, formDataMultiPart);

如何解决这个异常？

创建客户端时注册MultiPartWriter提供程序：

ClientConfig cc = new DefaultClientConfig();
Client client;

cc.getClasses().add(MultiPartWriter.class);
client = Client.create(cc);

如果使用Maven,这些是你在pom.xml中需要的依赖项：

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-client</artifactId>
    <version>1.17.1</version>
</dependency>
<dependency>
    <groupId>com.sun.jersey.contribs</groupId>
    <artifactId>jersey-multipart</artifactId>
    <version>1.17.1</version>
</dependency>
