获取某块代码的调用者信息，打印到控制台中

public static void printCaller() {
    try {
        StackTraceElement[] trace = new Throwable().fillInStackTrace().getStackTrace();
        String caller = "";
        String callingClass = "";
        String callFile = "";
        int lineNumber = 0;
        System.out.println("==========BEGIN OF CALLER INFO============");
        for (int i = 2; i < trace.length; i++) {
            callingClass = trace[i].getClassName();
            callingClass = callingClass.substring(callingClass
                    .lastIndexOf('.') + 1);
            caller = trace[i].getMethodName();
            callFile = trace[i].getFileName();
            lineNumber = trace[i].getLineNumber();
            String method = String.format(Locale.US, "[%03d] %s.%s(%s:%d)"
                    , Thread.currentThread().getId(), callingClass, caller, callFile, lineNumber);
            System.out.println(method);
        }
        System.out.println("==========END OF CALLER INFO============");
    } catch (Exception e) {
        e.printStackTrace();
    }
}
