日志工厂log4j和自带

一、mybatis自带的日志

mybatis-config.xml

加入

<settings>
    <setting name="logImpl" value="STDOUT_LOGGING"/>
</settings>

二、log4j

pom.xml

<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.17</version>
</dependency>

mybatis-config.xml

<settings>
    <setting name="logImpl" value="LOG4J"/>
</settings>

src同级目录建立logs文件夹

resource下建立log4j.properties

log4j.rootLogger=info,console,file
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=[%-5p] %m%n
log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.DatePattern='-'yyyy-MM-dd
log4j.appender.file.File=./logs/mct.log 目录及日志文件名
log4j.appender.file.Append=true
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=[%-5p] %d %37c %3x - %m%n

需要做日志的类UserDaoTest.java

package com.shuo.dao;

import com.shuo.pojo.User;
import com.shuo.utils.MybatisUtils;
import org.apache.ibatis.session.SqlSession;
import org.apache.log4j.Logger;
import org.junit.Test;

import java.util.HashMap;
import java.util.List;
import java.util.Map;


public class UserDaoTest {
    static Logger logger = Logger.getLogger(UserDaoTest.class);
    @Test
    public void test(){
        SqlSession session= MybatisUtils.getsqlsession();

        //List<User> objects = session.selectList("com.shuo.dao.UserDao.getUserList");
        UserDao mapper = session.getMapper(UserDao.class);
        List<User> userList = mapper.getUserList();
        for (User user : userList) {
            System.out.println(user.getId()+" "+user.getName()+" "+user.getPassword());
        }
        session.close();
    }
    @Test
    public void testlog4j(){
       logger.info("info:进入了testlog4j");
       logger.debug("debug:进入了testlog4j");
       logger.error("error:进入了testlog4j");
    }
