idea中slf4j的使用

以一个小例子说明日志的使用。

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class LogTest {
    private Logger logger = LoggerFactory.getLogger(getClass());
    public  void logger() { 
    logger.debug("This is debug message.");
    logger.info("This is info message.");    
    logger.error("This is error message.");
    }
}

//测试
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Main {
    public static void main(String[] args) {
        LogTest logTest = new LogTest();
        logTest.logger(); 
   }
}

log4j.rootLogger=debug,appender1
log4j.appender.appender1=org.apache.log4j.ConsoleAppender
log4j.appender.appender1.layout=org.apache.log4j.TTCCLayout
