打印当前在Java中运行的所有线程的所有堆栈跟踪

import java.util.Map;
import java.util.Set;

public class ThreadDumpExample {
    public static void main(String[] args) {
        // 获取所有活动线程的堆栈跟踪
        Map<Thread, StackTraceElement[]> allStackTraces = Thread.getAllStackTraces();

        // 打印线程信息
        for (Map.Entry<Thread, StackTraceElement[]> entry : allStackTraces.entrySet()) {
            Thread thread = entry.getKey();
            StackTraceElement[] stackTraceElements = entry.getValue();

            System.out.println("Thread: " + thread.getName());
            for (StackTraceElement element : stackTraceElements) {
                System.out.println("\tat " + element);
            }
            System.out.println(); // 空行分隔不同线程的堆栈跟踪
        }
    }
