Java检查死锁的方式
作者:互联网
模式死锁
public class DeadLockDemo {
public static void main(String[] args) {
String lockA = "lockA";
String lockB = "lockB";
new Thread(new HoldLock(lockA,lockB), "AA").start();
new Thread(new HoldLock(lockB,lockA), "BB").start();
}
}
class HoldLock implements Runnable{
private String lockA;
private String lockB;
public HoldLock(String lockA, String lockB) {
this.lockA = lockA;
this.lockB = lockB;
}
@SneakyThrows
@Override
public void run() {
synchronized (lockA) {
System.out.println(Thread.currentThread().getName() + "\t 自己持有:" + lockA + "\t 尝试获取:" + lockB);
TimeUnit.SECONDS.sleep(2);
synchronized (lockB) {
System.out.println(Thread.currentThread().getName() + "\t 自己持有:" + lockB + "\t 尝试获取:" + lockA);
}
}
}
}
方式1: 使用Jcosole查看
jconsole
方式2:
# 查看运行的Java进程 pid
jps -l
# 查看具体栈信息
jstack 24341
