Question

我有一个正在运行的线程，但现在我添加了一些它不再运行的代码。我尝试没有代码，它的工作原理。有人可以看看代码并确保我没有做错什么吗？

public class TimeBellServer extends Thread{
    static XBellDB[] xbellDB;
    static InterviewsDB[] interviewsDB;
    static boolean isPaused = false;
    static boolean bellsToday = false;

    public TimedBellServer() {

    }

    public void run() {
        try {
            xbellDB = new DBRefresh().refreshDB();
            System.out.println("Cody BAE");     
            //!this.isInterrupted() && 
            while(!TimedBellServer.isPaused) {
                SimpleDateFormat format = new SimpleDateFormat("HH:mm");
                Date current = new Date();
                String formatCurrent = format.format(current);
                String date = formatCurrent + ":00";
                boolean anyRung = false;

                System.out.println("--TimedBellServer: The current system time is: " + date);

                if(bellsToday) {
                    for(int i = 0; i != xbellDB.length; i++) {
                        if(xbellDB[i].time.equals(date)) {
                            System.out.println("--TimedBellServer: Ringing bell \"" + xbellDB[i].name + "\"");
                            TCPConnection.isPaused = true;

                            GPIO.initiate(18);
                            Thread.sleep(100);
                            GPIO.bellOn();
                            Thread.sleep(8000);
                            GPIO.bellOff();
                            Thread.sleep(100);
                            GPIO.unExport();

                            TCPConnection.isPaused = false;
                        }
                    }
                }

                if(ParentInterviews.parentInterviewsToday) {
                    if(interviewsDB[0].value.equals(date)) {
                        ParentInterviews.isPaused = false;
                        isPaused = true;
                        TCPConnection.isPaused = true;

                        System.out.println("--TimedBellServer: Parent Interviews First Block has started");
                    }

                    if(interviewsDB[1].value.equals(date)) {
                        ParentInterviews.isPaused = true;
                        TCPConnection.isPaused = false;

                        System.out.println("--TimedBellServer: Parent Interviews break has started");

                    }

                    if(interviewsDB[2].value.equals(date)) {
                        ParentInterviews.isPaused = false;
                        TCPConnection.isPaused = true;

                        System.out.println("--TimedBellServer: Parent Interviews Second Block has started");
                    }

                    if(interviewsDB[3].value.equals(date)) {
                        ParentInterviews.isPaused = true;
                        TCPConnection.isPaused = false;
                        isPaused = false;

                        System.out.println("--TimedBellServer: Parent Interviews Second Block has ended");
                    }
                }

                if(date.equals("00:01")) {
                    ParentInterviews.parentInterviewsToday = false;
                }

                if(anyRung == false) {System.out.println("--TimedBellServer: No bells rung");}
                Thread.sleep(60000);
            }
        } catch (Exception e) {

        }
    }

    public static void refresh(XBellDB[] db) {
        xbellDB = db;
    }

    public static void refreshInterviews(InterviewsDB[] db) {
        interviewsDB = db;
    }

我用它来运行代码：

Thread tbs = new Thread(new TimedBellServer());
tbs.start();

虽然这个问题并没有提供足够的相关信息，但我会冒这个有根据的猜测。该问题并未提供有关添加哪条代码导致代码无法运行的任何信息。

但是，由于您根本没有看到任何输出（println语句的结果），并且由于run方法中的第二个语句是println，因此我我确信t.start()几乎可以保证调用run方法，我认为该行

xbellDB = new DBRefresh().refreshDB();

导致异常。由于您的catch块正在捕获所有Exceptions并吞下它们，而没有任何记录，我认为您无法看到任何堆栈跟踪或任何其他相关信息。尝试添加类似

的内容

System.out.println(e.getMessage())

在catch方法的主run块内，看看它是否有帮助。
