将异常(getStackTrace)转化成String

private static String getStackMsg(Exception e) {

		StringBuffer sb = new StringBuffer();
		StackTraceElement[] stackArray = e.getStackTrace();
		for (int i = 0; i < stackArray.length; i++) {
			StackTraceElement element = stackArray[i];
			sb.append(element.toString() + "\n");
		}
		return sb.toString();
	}

	private static String getStackMsg(Throwable e) {

		StringBuffer sb = new StringBuffer();
		StackTraceElement[] stackArray = e.getStackTrace();
		for (int i = 0; i < stackArray.length; i++) {
			StackTraceElement element = stackArray[i];
			sb.append(element.toString() + "\n");
		}
		return sb.toString();
	}
