利用StackTrace堆棧軌跡獲取某個(gè)時(shí)間的調(diào)用堆棧狀態(tài)。

執(zhí)行結(jié)果：

Hello dsp! 851 ######### aMethod ######### aMethod com.dsp.demo.TechDemo TechDemo.java ******** aMethod ****** ######### bMethod ######### bMethod com.dsp.demo.TechDemo TechDemo.java ******** bMethod ****** ######### cMethod ######### cMethod com.dsp.demo.TechDemo TechDemo.java ######### saveA ######### saveA saveA ******** saveA ****** ######### updateB ######### updateB ******** updateB ****** ******** cMethod ******
