使用process explorer分析JAVA进程

使用process explorer分析JAVA进程

平时我们在处理性能相关问题时，有时只知道JAVA.exe占用CPU很高，而不知道到底哪些JAVA进程占用比较高的CPU；现在笔者通过使用process explorer来分析具体的JAVA进程，有帮于定位程序中的相关代码。

1.下载一个process explorer,其实process explorer就是一个增强版的资源管理器，不同于平常的资源管理器的是，他能分析出来具体某个EXE程序，到底有哪些进程组成；

2.使用process explorer很简单，打开process explorer，找到相关的JAVA.exe，点属性可以看到所有属于该EXE的进程信息(包括进程号，占用CPU资源等信息)；我们任意找个进程号3220(十进制)，也许你会问这有什么用，还是对应不到具体的程序里面的相关代码；这就需要打印出当前JAVA应用程序的进程堆栈信息

3.打印出当前JAVA应用的JVM堆栈信息（在apusic下为例CTRL+break,也可以用JDK1.6下的jps和jstack命令，可以获得完整的thread ）：这里的进程号是16进制的，所以需进行转换3220—>C94，然后就可以以此去找进程，灰色部分标识即是。

当前在处理实际问题时，我们一般是找CPU占用比较靠前的几个进程来进行分析，这样更具针对性；
