jstack的使用：Java栈追踪工具

luoye 2021年06月11日 编程语言 393 0

jstack命令打印指定Java进程、核心文件或远程调试服务器的Java线程的Java 栈跟踪。对于每个Java框架，将打印完整的类名、方法名、字节码索引(BCI)和行号(如果可用)。使用-m选项，jstack命令使用程序计数器(PC)打印所有线程的Java和本机帧。对于每个本机帧，打印距离PC最近的本机符号(如果可用)

全称: stack trace for java

形式：jstack -option pid

       -F
              Force a stack dump when jstack [-l] pid does not respond.

       -l
              Long listing. Prints additional information about locks such as a list of owned java.util.concurrent ownable synchronizers. 

       -m
              Prints a mixed mode stack trace that has both Java and native C/C++ frames.

1，jstack -l 961012

长清单，打印关于锁的附加信息，例如拥有 JUC的 synchronizers 的一个list

jstack -l 961012 > jstack.txt
把锁信息的信息打印到一个文件去，方便查看。

也不太多，也粘贴出来看看。

这个放眼望去，可读性太不好了，连个类每啥的都没有，全是地址。。。

难。
