现在我想通了.这是我的解决方案:

Now I figure it out. Here is my solution:

public static void main(String[] args) {

    try {
        Client client = Client.create();

        WebResource webResource = client.resource(baseuri);

        String input = "{"switch": "00:00:00:00:00:00:00:01", "
                + ""name":"flow-mod-1", "priority":"32768", "
                + ""ingress-port":"1","active":"true", "
                + ""actions":"output=2"}";

        // POST method
        ClientResponse response = webResource.accept("application/json")
                .type("application/json").post(ClientResponse.class, input);

        // check response status code
        if (response.getStatus() != 200) {
            throw new RuntimeException("Failed : HTTP error code : "
                    + response.getStatus());
        }

        // display response
        String output = response.getEntity(String.class);
        System.out.println("Output from Server .... ");
        System.out.println(output + "
");
    } catch (Exception e) {
        e.printStackTrace();
    }

}
