mybatis的两种日志

四、日志

setting设置：logImpl（key） ：

• SLF4J
• LOG4J
• LOG4J2
• JDK_LOGGING
• COMMONS_LOGGING
• STDOUT_LOGGING
• NO_LOGGING
  由于太多，我就简单介绍和配置一下我自己使用的日志；

第一种：STDOUT_LOGGING

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

日志输出：

第二种：LOG4J

1.先导入包

<!-- https://mvnrepository.com/artifact/log4j/log4j -->
<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.17</version>
</dependency>

2.setting设置

#将等级为DEBUG的日志信息输出到console和file这两个目的地，console和file的定义在下面的代码
log4j.rootLogger=DEBUG,console,file

#控制台输出的相关设置
log4j.appender.console = org.apache.log4j.ConsoleAppender
log4j.appender.console.Target = System.out
log4j.appender.console.Threshold=DEBUG
log4j.appender.console.layout = org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=[%c]-%m%n

#文件输出的相关设置
log4j.appender.file = org.apache.log4j.RollingFileAppender
#存储的位置
log4j.appender.file.File=./log/saxon.log
#存储的最大大小，超出这个就在生成另一个
log4j.appender.file.MaxFileSize=10mb
log4j.appender.file.Threshold=DEBUG
log4j.appender.file.layout=org.apache.log4j.PatternLayout
#格式
log4j.appender.file.layout.ConversionPattern=[%p][%d{yy-MM-dd}][%c]%m%n
#是否追加
log4j.appender.file.Append=false

#日志输出级别
log4j.logger.org.mybatis=DEBUG
log4j.logger.java.sql=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.ResultSet=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG

3.测试

import org.apache.log4j.Logger;
static Logger logger = Logger.getLogger (UserDaoTest.class);
@Test
 public  void  testLog4j(){
        logger.info ("我是谁");
        logger.error ("我是谁");
        logger.debug ("我是谁");
}

其他的日志我也不会，慢慢学习中；
