flightrecorder

run application

java -XX:StartFlightRecording:filename=recording.jfr,duration=10s -jar target/flightrecorder-0.0.1-SNAPSHOT.jar

spring boot 使用jfr 功能，必须按照FlightRecorderApplication main method 中的实现，需要将FlightRecorderApplicationStartup 加入到ApplicationStartup 中

不然不能获得jfr 的信息

jdk mission control

open the record.jfr file with jmc

run DBB
