'is it possible to using jstack to print the the method each line of code execute time
Today I facing a problem that the spring boot(Java 8) production one methond execute takes a long time. I only have the jdk tools in production environment. Is it possible to print the java method execute time of each line of code so that I could know which line take the longest time. I have tried using jstack and jmap but it seems could not work like this, I have read my source code and still did not figure out which line cause this problem. what should I do to print the execute time of each line of code in the production method code? is it possible to do like this?
