异常使用总结

1、日志的打印基础使用： org.slf4j.Logger

exception不是字符串，不需要 {}

@Test
	public void test() {
		String string = "test str··";
		try {
			System.out.println("开始执行代码····");
			int i = 1/0;
		} catch (Exception e) {
			logger.info("info {} Occured exception:", string, e);
			logger.info("---------------------------");
			logger.warn("warn {} Occured exception:", string, e);
			logger.info("---------------------------");
			logger.error("error {} Occured exception:", string, e);
		}finally {
			System.out.println("执行最后代码finally.");
		}
	}
