3、测试demo

App.java

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class App {
	private final static Logger logger = LoggerFactory.getLogger(App.class);
	public static void main(String[] args) {
		for(int i=0;i<1000000;i++){
			logger.info("logback info 成功了");
			logger.error("logback error 成功了");
			logger.debug("logback debug 成功了");
			logger.warn("logback warn 成功了");
			logger.trace("logback trace 成功了");
		}
	}
}
