log4j 1.x版本 纯java项目配置入门学习

 依赖包：log4j-1.2.17.jar

 测试代码：

package cn.com.agree.hx.logger.test;

import java.io.File;

import org.apache.log4j.Level;
import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;
import org.apache.log4j.spi.LoggerRepository;

public class LoggerTest {
	
	private static Logger logger = Logger.getLogger(LoggerTest.class);
	static {
//		logger.setAdditivity(additive);
		
		String configPath = System.getProperty(\"user.dir\") + File.separator + \"config\"+ File.separator + \"log4j.properties\";
		PropertyConfigurator.configure(configPath);
	
		LoggerRepository  loggerRepository = logger.getLoggerRepository();
		Level level = loggerRepository.getRootLogger().getLevel();
		System.out.println(level.toInt());
		loggerRepository.getRootLogger().setLevel(Level.DEBUG);
//		Level level2 = loggerRepository.getRootLogger().getLevel();
//		System.out.println(level2.toInt());
//		logger.setLevel(Level.INFO);
	}
	
	
	public void testLoggerDebug() {
		logger.debug(\"debug\");
		logger.info(\"info\");
		logger.warn(\"warn\");
		logger.error(\"error\");
		logger.fatal(\"fatal\");
		try {
			throwException();
		}catch (Exception e) {
			logger.error(\"出现的错误：\", e);
		}
	}
	
	public void throwException() throws Exception {
		throw new Exception();
	}
	
	public static void main(String[] args) {
       LoggerTest loggerTest = new LoggerTest();
       loggerTest.testLoggerDebug();
    }

}
