一、导入后台连接websocket的客户端依赖
<dependency>
<groupId>org.java-websocket</groupId>
<artifactId>Java-WebSocket</artifactId>
<version>1.3.5</version>
</dependency>
二、实现客户端
@Component
public class WebSocketConfig {
@Bean
public WebSocketClient webSocketClient() {
try {
WebSocketClient webSocketClient = new WebSocketClient(new URI("ws://localhost:8085/websocket/test"),new Draft_6455()) {
@Override
public void onOpen(ServerHandshake handshakedata) {
log.info("[websocket] 连接成功");
}
@Override
public void onMessage(String message) {
log.info("[websocket] 收到消息={}",message);
}
@Override
public void onClose(int code, String reason, boolean remote) {
log.info("[websocket] 退出连接");
}
@Override
public void onError(Exception ex) {
log.info("[websocket] 连接错误={}",ex.getMessage());
}
};
webSocketClient.connect();
return webSocketClient;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}
三、使用客户端发送消息
@Component
public class ScoketClient {
@Autowired
private WebSocketClient webSocketClient;
@Override
public void groupSending(String message) {
webSocketClient.send(message+"---6666");
}
@Override
public void appointSending(String name, String message) {
webSocketClient.send("TOUSER"+name+";"+message);
}
}
四、编写测试接口
@RestController
@RequestMapping("/websocket")
public class IndexController {
@Autowired
private ScoketClient webScoketClient;
@GetMapping("/sendMessage")
public String sendMessage(String message){
webScoketClient.groupSending(message);
return message;
}
}
