现在我知道了。这是我的解决方案：
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 pre if (response.getStatus() != 200) { throw new RuntimeException("Failed : HTTP error pre : " + response.getStatus()); } // display response String output = response.getEntity(String.class); System.out.println("Output from Server .... "); System.out.println(output + "n"); } catch (Exception e) { e.printStackTrace(); }}
