1 導(dǎo)入commons-logging.jar和log4j-1.2.15.jar包

2 在web項(xiàng)目下增加l og4j.properties

3?log4j.properties的內(nèi)容如下

# debug config start
log4j.rootLogger=debug,stdout,log,errorlog,debuglog

?#?? degug config over

4 因?yàn)?Logger每次調(diào)用前需要傳入一個(gè)class參數(shù),所以自定義MyLooger4j類,用靜態(tài)工廠模式實(shí)現(xiàn)Logger

package Factory.Log4j;import mybatis.model.unit.ProcedureJunitTest;import org.apache.log4j.Logger;public class MyLogger4j {private static Logger logger;static{System.out.println("here");logger = Logger.getLogger(MyLogger4j.class);}public static void info(String info){logger.info(info);};public static void error(String error){logger.error(error);};public static void debug(String debug){logger.debug(debug);};}
5 測(cè)試類

package mybatis.model.unit;import Factory.Log4j.MyLogger4j;public class Log4JTest {public static void main(String[] args) {MyLogger4j.debug("Log4JTest debug");MyLogger4j.error("Log4JTest error");MyLogger4j.info("Log4JTest info");}}

debug.log

error.log
