我在程序中创建了一些线程。在这里,我使用了join方法,以便主线程将等待所有线程。但是,每当我运行该程序时,它的所有信息消息都无法完成打印,但程序仍然无法顺利结束。有人可以帮助我摆脱困境吗?

下面是我的代码:

ArrayList<DeployerThread> threadsarrforjoin = new ArrayList<DeployerThread>();

for (int i = 0; i < serverList.size(); i++) {
    logger.debug("Inside for loop of buildParameterList()");
    if (serverList.get(i).ServerType.toString().equalsIgnoreCase("SS") &&
        serverList.get(i).GroupNo.toString().equalsIgnoreCase(groupNo)) {
        try {
            nameofthreads.add("PhoinexHyperlink[" +
                               serverList.get(i).ServerIP + "_" +
                               serverList.get(i).ServerType + "]");
            DeployerThread deployerThread = new DeployerThread(serverList.get(i), action);
            logger.info("---- Start thread execution ---- ");
            deployerThread.start();
            threadsarrforjoin.add(deployerThread);

            Thread.sleep(5000);
        } catch (Exception e) {
            System.out.println(e);
            this.logger.error(e.toString());
          }
        count++;
    }
}

for (int i = 0; i < threadsarrforjoin.size(); i++) {
    try {
        this.threadsarrforjoin.get(i).join();
    } catch (InterruptedException ex) {
        logger.error(ex.getMessage());
        Logger.getLogger(StartStopWebServers.class.getName()).log(Level.SEVERE, null, ex);
      }
}
logger.info(taskName + " Completed");


以下是DeployerThread的代码:

public DeployerThread(ServerConfig serverConfig, String actn, String WEBPROC, String WEBPROC1, String WEBPROCIgnore) {
            logger.debug("Inside DeployerThread constructor");
            logger.debug("serverConfig=" + serverConfig);
            logger.debug("Action=" + actn);
            setServerConfig(serverConfig);
            setTaskaction(actn);
            setWebproc(WEBPROC);
            setWebproc1(WEBPROC1);
            setWebprocignore(WEBPROCIgnore);


        }

        public final ServerConfig getServerConfig() {
            return serverConfig;
        }

        public final void setServerConfig(ServerConfig serverConfig) {
            this.serverConfig = serverConfig;
        }

        public void run() {

            logger.debug("Inside threads run method : Start");
            count++;
            logger.debug("Thread number >>>>" + count + "<<<<");


            Thread.currentThread().setName("[" + serverConfig.ServerIP + "_" + serverConfig.ServerType + "]");
           // threadsarrforjoin.add(Thread.currentThread());
            logger.debug("Name given to this thread=" + "[" + serverConfig.ServerIP + "_" + serverConfig.ServerType + "]");
            org.slf4j.MDC.put("userid", buildPath + "/" + taskName + "/" + taskaction + "_" + Thread.currentThread().getName() + ".log");

            logger.info("Deployment started on " + serverConfig.ServerIP + " for " + serverConfig.ServerType + " at " + dateTimeStamp);
            logger.debug("taskname=" + taskName + "_" + serverConfig.ServerType);

            logger.debug("buildPath=" + buildPath);
            runSSH(serverConfig, action, webproc, webproc1, webprocignore);
            logger.debug("Outside threads run method : End");



        }
    }

最佳答案

用JSCH打开的ssh似乎没有终止;非守护程序线程Connect thread仍然有效。如果您说过程序正常运行,请确保从jsch会话断开连接。

您还可以将会话上的DaemonThread属性设置为true,以避免由ConnectThread session.setDaemonThread(true)引起的挂起。必须在connect()之前调用。
