如何打印Java转储的托管和非托管调用堆栈？
在.Net中，我们可以使用打印从转储中打印调用堆栈中的托管和非托管代码方法，我是否可以知道Java中是否有一个等效程序也可以打印托管和非托管调用堆栈？您正在比较两个无法比较的东西 一方面，您指的是如何打印Java转储的托管和非托管调用堆栈？,java,debugging,windbg,dump,Java,Debugging,Windbg,Dump,在.Net中，我们可以使用打印从转储中打印调用堆栈中的托管和非托管代码方法，我是否可以知道Java中是否有一个等效程序也可以打印托管和非托管调用堆栈？您正在比较两个无法比较的东西 一方面，您指的是！DumpStack，它是调试器的插件。调试器是为特定操作系统编写的，在本例中是WinDbg for Windows。当然，Windows调试器知道如何读取本机调用堆栈 另一方面，您希望从JVM获取该信息。JVM是Java虚拟机的缩写。如果您使用过VMWare等虚拟机，您就会知道虚拟机运行的是不同的“操
！DumpStack如果您考虑在Windows主机上运行Linux VM，并且在VM中使用Linux调试器（GDB），它会显示Windows调用堆栈吗？不，不会的-至少当虚拟机设计正确时
将其映射到JVM，您应该无法从Java程序内部看到本机调用堆栈，因为它在VM中运行 那么，为什么！DumpStack！DumpStack我在WinDbg行业工作了7年，发现了很多用于各种用途的插件，但没有用于显示Java调用堆栈的插件。我很想看到一个，因为我有不止一个使用案例。首先，我想评论一下，这个问题对我来说似乎很好，我发现结束你之前的问题和一些评论令人震惊，再次证明了这么做的许多错误 如果问这些关于.NET的问题是可以的，问他们关于Java的问题也是可以的，即使答案是“你不能” （我将加入进来并吹毛求疵：“托管”是Microsoft对在CLR下运行的代码的术语。您想问这样的问题：“如何在WinDbg中获得一个既包含JVM本机代码又包含其中运行的JITted Java代码的可用堆栈跟踪？”） 现在谈谈你的问题：
简介 不幸的是，我不知道有什么工具或WinDbg插件可以做到这一点，但我认为有一种方法可以让你自己制作一个。（我想我可能会去，但我找不到时间，所以我想我至少应该给你信息。既然你问了两次这个问题，我想这可能很重要，所以你会费心采取必要的措施。） 解决您的问题可以分为两部分：
src/c/perf map file.c- 可能会将其转换为带有的DBG文件
- 也许甚至可以尝试使用它来制作PDB
您有一个这样做的代码（由blabb编写，他在windbg标记的SO中处于活动状态）。在www.woodmann.com上曾经有一个二进制代码，但是这个网站现在对我不起作用（而且已经很久没有了）。似乎有一个二进制文件
C:\Users\conio\Desktop\code\JNA2>"C:\Program Files\Java\jdk1.8.0_102\bin\jstack.exe" -?
Usage:
jstack [-l] <pid>
(to connect to running process)
jstack -F [-m] [-l] <pid>
(to connect to a hung process)
jstack [-m] [-l] <executable> <core>
(to connect to a core file)
jstack [-m] [-l] [server_id@]<remote server IP or hostname>
(to connect to a remote debug server)
Options:
-F to force a thread dump. Use when jstack <pid> does not respond (process is hung)
-m to print both java and native frames (mixed mode)
-l long listing. Prints additional information about locks
-h or -help to print this help message
