【声明，如果是docker启动的服务，可以在进入容器内后，再使用如下命令操作】

【docker exec -it 容器ID  /bin/bash     即可进入容器内】

【如果不是docker启动的服务，可以直接在宿主机使用下面操作】

 

简易操作步骤：

1.使用top命令获取所有Linux服务器上的进程PID以及相关信息

top

 

 

2.使用【top -H -p 进程PID】命令，可以获取到具体某个进程下各个线程的相关信息

如上可以看到java进程的PID是1

top -H -p 1

 

 

3.获取到其中的某个线程的PID，可以使用下面的命令获取到16进制的PID

例如，获取到PID为42的线程 对应的十六进制

printf "%x\n" 42

 

 

4.使用jstack命令 配合第三步的十六进制PID，可以具体定位到这个线程的情况

jstack -l 1 | grep 2a

jstack -l java进程PID | grep 具体线程十六进制PID

 

 

然后可以根据这个获取结果进行分析

 

New: 当线程对象创建时存在的状态，此时线程不可能执行；Runnable：当调用thread.start()后，线程变成为Runnable状态。只要得到CPU，就可以执行；Running：线程正在执行；Waiting：执行thread.join()或在锁对象调用obj.wait()等情况就会进该状态，表明线程正处于等待某个资源或条件发生来唤醒自己；Timed_Waiting：执行Thread.sleep(long)、thread.join(long)或obj.wait(long)等就会进该状态，与Waiting的区别在于Timed_Waiting的等待有时间限制；Blocked：如果进入同步方法或同步代码块，没有获取到锁，则会进入该状态；Dead：线程执行完毕，或者抛出了未捕获的异常之后，会进入dead状态，表示该线程结束其次，对于jstack日志，我们要着重关注如下关键信息Deadlock：表示有死锁Waiting on condition：等待某个资源或条件发生来唤醒自己。具体需要结合jstacktrace来分析，比如线程正在sleep，网络读写繁忙而等待Blocked：阻塞Waiting on monitor entry：在等待获取锁in Object.wait()：获取锁后又执行obj.wait()放弃锁对于Waiting on monitor entry 和 in Object.wait()的详细描述：Monitor是 Java中用以实现线程之间的互斥与协作的主要手段，它可以看成是对象或者 Class的锁。每一个对象都有，也仅有一个 monitor。从下图中可以看出，每个 Monitor在某个时刻，只能被一个线程拥有，该线程就是 "Active Thread"，而其它线程都是 "Waiting Thread"，分别在两个队列 " Entry Set"和 "Wait Set"里面等候。在 "Entry Set"中等待的线程状态是 "Waiting for monitor entry"，而在 "Wait Set"中等待的线程状态是 "in Object.wait()"

 

 

5.当然jstack命令可以不指定具体某个线程的十六进制PID,只指定java进程的PID,可以获取到完整的信息

jstack -l 1

jstack -l 只指定java进程PID
