JAX-WS Dispatch Request设置Content-Type

Question

我正在尝试使用Service/Dispatch机制发布JAX-RS资源.问题是传出请求的Content-Type被锁定text/xml.例如,我无法看到将此更改为其他类型的方法application/xml.

RESTfull Web服务仅使用application/xml和application/json.这是我使用的代码:

public static void main(String[] args) {
    QName qName = new QName("GREETINGS");

    Service service = Service.create(qName);
    service.addPort(qName, HTTPBinding.HTTP_BINDING, "http://localhost:8081/gf-ws-1/resources/greetings");

    // change headers of the outgoing request
    Map<String, Object> headers = new HashMap<String, Object>();
    headers.put("Content-Type", Arrays.asList(new String[] {"application/xml"}));
    headers.put("Accept", Arrays.asList(new String[] {"zoo"}));
    headers.put("foo", Arrays.asList(new String[] {"bar"}));

    Dispatch<Source> dispatch = service.createDispatch(qName, Source.class, Service.Mode.PAYLOAD);
    dispatch.getRequestContext().put(MessageContext.HTTP_REQUEST_METHOD, "POST");
    dispatch.getRequestContext().put(MessageContext.HTTP_REQUEST_HEADERS, headers);

    dispatch.invokeOneWay(new StreamSource(new StringReader("<?xml version='1.0' encoding='UTF-8'?><greeting><value>Hello World!</value></greeting>")));

    // get the response code: [HTTP/1.1 415 Unsupported Media Type] because of content type
    System.out.println(((Map<String, Object>) dispatch.getResponseContext().get(MessageContext.HTTP_RESPONSE_HEADERS)).get(null));
}

的Accept报头被修改为zoo,foo头部被添加与值bar,但Content-Type保持不变.我想我可以使用过滤器并Content-Type根据某些条件修改,甚至基于foo标题,但这似乎反直觉.

以下是请求的所有标头:

POST /gf-ws-1/resources/greetings HTTP/1.1
Accept: zoo
Content-Type: text/xml
foo: bar
User-Agent: Metro/2.2.0-1 (tags/2.2.0u1-7139; 2012-06-02T10:55:19+0000) JAXWS-RI/2.2.6-2 JAXWS/2.2 svn-revision#unknown
Host: localhost:8080
Connection: keep-alive
Content-Length: 86

任何帮助表示赞赏.

如果要自定义整个消息，则必须使用 Service.Mode.MESSAGE 而不是 Service.Mode.PAYLOAD。

Content-Type 是与消息相关的属性。
