log4j测试

 

 

 

 在用log4j的时候，需要导入相关的log的jar包

 

import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;


public class MyLogTest {
	static Logger logger = Logger.getLogger(MyLogTest.class.getName());

	public static void main(String[] args){
		PropertyConfigurator.configure("src/Log4j.properties");
		MyLogTest.logger.info("test begining");
		logger.debug("lihua");
		logger.error("error test");
	}
}
