Rapid printing of JSTACK and JSTAT

Rapid printing of JSTACK and JSTAT

At work, sometimes the JBoss server is on the machine and you need to use the command line to obtain the JSTACK and JSTAT logs for analysis of the cause. However, to obtain the preceding logs, You need to first query the process number, which is basically not allowed due to time issues in production.

Therefore, a batch processing command is written to complete this action.

Restrictions:

Only one java.exe process is running

You must add the java_home \ bin directory to the path environment variable.
