首先,创建一个服务器端的 Java WebSocket 实现,这里使用 Tomcat 7 作为服务器: import javax.websocket.*;@ServerEndpoint("/websocketendpoint")
public class MyWebSocketServer {@OnOpen
public void onOpen(Session session){
System.out.println("Open Connection ...");
}@OnClose
public void onClose(Session session){
System.out.println("Close Connection ...");
}@OnMessage
public String onMessage(String message, Session session){
System.out.println("Message from the client: "+message);
String echoMsg = "Echo from the server : "+ message;
return echoMsg;
}@OnError
public void onError(Throwable e){
e.printStackTrace();
}}接下来,创建一个客户端的 Java WebSocket 实现,这里使用 Jetty 来支持 WebSocket 客户端:import javax.websocket.*;@ClientEndpoint
public class MyWebSocketClient {@OnOpen
public void onOpen(Session session){
System.out.println("Open Client Connection ...");
try {
session.getBasicRemote().sendText("Hello Server");
} catch (IOException e) {
e.printStackTrace();
}
}@OnMessage
public void onMessage(String message, Session session){
System.out.println("Message from the server: "+message);
}@OnClose
public void onClose(Session session){
System.out.println("Close Client Connection ...");
}@OnError
public void onError(Throwable e){
e.printStackTrace();
}}接着,编写一个测试用例来测试 WebSocket 通信:import javax.websocket.ContainerProvider;
import javax.websocket.WebSocketContainer;public class TestWebSocket {public static void main(String[] args) {
try {
WebSocketContainer container= ContainerProvider.getWebSocketContainer(); String uri="ws://localhost:8080/WebSocketExample/websocketendpoint"; Session session = container.connectToServer(MyWebSocketClient.class, URI.create(uri)); session.getBasicRemote().sendText("Hello Server"); Thread.sleep(100); session.close();
} catch (Exception e) {
e.printStackTrace();
}}}最后,编译和运行代码,用以确保 WebSocket 测试用例能够正常运行:javac TestWebSocket.java
java TestWebSocket运行结果如下:
Open Connection ...
Message from the client: Hello Server
Echo from the server: Hello Server
Close Connection ...
