Logback - spring 配置 logback.xml （彩色）

有一个公司的老项目，日志文件是放在工程里面配置的，启动的时候自动加载logback.xml文件，给我们后期维护和修改带来极大的不便；
开始不清楚缘由，看到项目里有使用slft4j，也有java自带的log工具包，权衡利弊后，决定吧logback放在外面，并且实现log按照日期每天生成一个log文件，但是多次试验后，发现放在部署目录下并不起作用，奇了怪了，后来忽然想起来，项目的配置文件在启动的main方法是单独加载的，是不是也要把这个logback.xml也单独拎出来，并且在启动的时候加载到项目呢；

//load logback.xml
private static void populateLogback(String path) {
		String file_name = path + "/logback.xml" ;
		File logbackFile = new File(file_name);
		LOGGER.debug("Absolute property file path with file name: {}", logbackFile.getAbsolutePath());
		if (logbackFile.exists()) {
			LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
			JoranConfigurator configurator = new JoranConfigurator();
			configurator.setContext(lc);
			lc.reset();
			try {
				configurator.doConfigure(logbackFile);
			} catch (JoranException e) {
				e.printStackTrace(System.err);
				System.exit(-1);
			}
		}
	}
