JAVA debug添加类名、方法名、行号

编码实现

    private static String getLogContextInfo(int traceLevel) {
        StackTraceElement ste = new Throwable().getStackTrace()[traceLevel];
        String fileName = ste.getFileName();
        String methodName = ste.getMethodName();
        fileName = fileName.substring(0, fileName.length() - 5);
        return "[" + fileName + "][" + methodName + "][L" + ste.getLineNumber() + ']';
    }
