利用StackTrace堆栈轨迹获取某个时间的调用堆栈状态。

1 package com.dsp.demo; 2  3 public class TechDemo { 4  5     public static void main(String[] args) { 6         System.out.println("Hello dsp!"); 7  8         System.out.printf("%x\n", 2129); 9 10         aMethod();11     }12 13     private static String getExecutingMethodName() {14         StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();15         StackTraceElement e = stackTrace[2];16         return e.getMethodName();17     }18 19     private static void aMethod() {20         System.out.println("######### aMethod #########");21         //String executingMethodName = Thread.currentThread().getStackTrace()[2].getMethodName();22         String executingMethodName = getExecutingMethodName();23         System.out.println(executingMethodName);24         String className = Thread.currentThread().getStackTrace()[2].getClassName();25         System.out.println(className);26         String fileName = Thread.currentThread().getStackTrace()[2].getFileName();27         System.out.println(fileName);28         System.out.println("******** aMethod ******");29 30         bMethod();31     }32 33     private static void bMethod() {34         System.out.println("######### bMethod #########");35         // String executingMethodName = Thread.currentThread().getStackTrace()[2].getMethodName();36         String executingMethodName = getExecutingMethodName();37         System.out.println(executingMethodName);38         String className = Thread.currentThread().getStackTrace()[2].getClassName();39         System.out.println(className);40         String fileName = Thread.currentThread().getStackTrace()[2].getFileName();41         System.out.println(fileName);42         System.out.println("******** bMethod ******");43 44         cMethod();45     }46 47     private static void cMethod() {48         System.out.println("######### cMethod #########");49         String executingMethodName = getExecutingMethodName();50         System.out.println(executingMethodName);51         String className = Thread.currentThread().getStackTrace()[2].getClassName();52         System.out.println(className);53         String fileName = Thread.currentThread().getStackTrace()[2].getFileName();54         System.out.println(fileName);55 56         saveA();57         updateB();58 59         System.out.println("******** cMethod ******");60     }61 62     public static void saveA() {63         System.out.println("######### saveA #########");64         // ###65         String executingMethodName = getExecutingMethodName();66         System.out.println(executingMethodName);67 68         // ###69         String name = new Object(){}.getClass().getEnclosingMethod().getName();70         System.out.println(name);71         System.out.println("******** saveA ******");72     }73 74     public static void updateB() {75         System.out.println("######### updateB #########");76         String executingMethodName = getExecutingMethodName();77         System.out.println(executingMethodName);78         System.out.println("******** updateB ******");79     }80 81 }

执行结果：

Hello dsp!851######### aMethod #########aMethodcom.dsp.demo.TechDemoTechDemo.java******** aMethod ******######### bMethod #########bMethodcom.dsp.demo.TechDemoTechDemo.java******** bMethod ******######### cMethod #########cMethodcom.dsp.demo.TechDemoTechDemo.java######### saveA #########saveAsaveA******** saveA ******######### updateB #########updateB******** updateB ************** cMethod ******
