本次将连接人数、发送还是连接的状态、页面信息处理加以完善
如果您这边分开调用理解的不是太好可以借鉴我之前发布的websocket专题1~5参考查阅（忘记了是否都被发布）
1.Timer java文件实现runnable接口
import java.util.HashMap;import java.util.Map;import javax.websocket.OnMessage;import javax.websocket.Session;import javax.websocket.server.ServerEndpoint;import org.apache.log4j.Logger;import org.sceu.tkdtas.Timer;import org.sceu.tkdtas.constants.Constants;import org.springframework.util.StringUtils;import com.google.gson.Gson;/** * 计时器 * @author sunyan * */@ServerEndpoint("/timer")public class WSTimer extends WSBase {Logger log = Logger.getLogger(WSTimer.class);Gson gson = new Gson();@Override@OnMessage public void onMessage(String msg, Session session) {log.info("【REQ_MSG】:" + msg);@SuppressWarnings("unchecked")Map reqJsonMap = gson.fromJson(msg, HashMap.class);
String requestType = (String)reqJsonMap.get(Constants.WS_REQPARA_REQUESTTYPE);
if(StringUtils.isEmpty(requestType)) {
return;
}
boolean timerControler = false;
if(Constants.WS_REQTYPE_START.equals(requestType)) {
timerControler = true;
}else if(Constants.WS_REQTYPE_PAUSE.equals(requestType)) {
timerControler = true;
}else if(Constants.WS_REQTYPE_START_PAUSE_STOP.equals(requestType)) {
timerControler = true;
}else if(Constants.WS_REQTYPE_RESET_tIME.equals(requestType)) {
timerControler = true;
}
if(!timerControler) {
log.info("非时间操作！");
return;
}
Timer timer = new Timer(reqJsonMap);
Thread thread = new Thread(timer);
thread.start();
log.info("【" + Thread.currentThread().getName()+"】 开始执行");
super.onMessage(msg, session);
}
}
2.Timer java文件 具体实现每秒向页面发送时间
