MyBatis02-log4j

如何在MyBatis框架中使用日志log4j?

1：引入log4j的依赖

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

2：在resources下创建log4j的xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration >

    <appender name="STDOUT" class="org.apache.log4j.ConsoleAppender">

        <param name="Encoding" value="UTF-8"/>

        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%-5p %d{MM-dd HH:mm:ss,SSS} %m (%F:%L) \n"/>
        </layout>

    </appender>

    <logger name="java.sql">
        <level value="debug"/>
    </logger>

    <logger name="org.apache.ibatis">
        <level value="info"/>
    </logger>

    <root>
        <level value="debug"/>
        <appender-ref ref="STDOUT"/>
    </root>

</log4j:configuration>

3：测试
