整合log4j

引入依赖

<dependency>
      <groupId>log4j</groupId>
      <artifactId>log4j</artifactId>
      <version>1.2.12</version>
    </dependency>

 

resources目录下添加log4j.xml配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/' >

    <appender name="STDOUT"
              class="com.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>

 

mybatis-config.xml中添加配置（注意该配置中添加标签有顺序要求）

 <settings>
        <!--标准的日志-->
        <setting name="logImpl" value="STDOUT_LOGGING"/>
 </settings>
