spring boot log4j2 +mybatis 打印SQL

1. 首先引入所需的依赖 （2.16.0版本的log4j2）

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
</dependency>

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-slf4j-impl</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
        </exclusion>
    </exclusions>
</dependency>

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.32</version>
</dependency>

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
</dependency>

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-jul</artifactId>
</dependency>

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-web</artifactId>
</dependency>
<!-- +++++++++++++++++++++++ 日志 log4j start +++++++++++++++++++++++ -->

2. 第二步创建 src/main/resources/log4j2.xml  定义自己的日志格式和输入文件目录

<?xml version="1.0" encoding="UTF-8"?>
<configuration status="OFF" monitorInterval="1800">
    <Properties>
        <property name="LOG_PATTERN" value="[ %date{yyyy-MM-dd HH:mm:ss.SSS} ] [ %thread ] %-5level %logger{36} - %msg%n" />
        <property name="FILE_NAME" value="admin" />
        <property name="FILE_PATH" value="/data/logs/" />
    </Properties>

    <appenders>
        <Console  name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="${LOG_PATTERN}"/>
        </Console>

        <RollingFile name="RollingFileInfo" fileName="${FILE_PATH}/${FILE_NAME}/${FILE_NAME}_info.log"
                     filePattern="${FILE_PATH}/${FILE_NAME}-INFO-%d{yyyy-MM-dd-HH}_%i.log.gz">
            <ThresholdFilter level="info" onMatch="ACCEPT" onMismatch="DENY"/>
            <PatternLayout pattern="${LOG_PATTERN}"/>
            <Policies>
                <TimeBasedTriggeringPolicy interval="1"/>
                <SizeBasedTriggeringPolicy size="10MB"/>
            </Policies>
            <DefaultRolloverStrategy max="15"/>
        </RollingFile>

        <RollingFile name="RollingFileError" fileName="${FILE_PATH}/${FILE_NAME}/${FILE_NAME}_error.log"
                     filePattern="${FILE_PATH}/${FILE_NAME}-ERROR-%d{yyyy-MM-dd-HH}_%i.log.gz">
            <ThresholdFilter level="error" onMatch="ACCEPT" onMismatch="DENY"/>
            <PatternLayout pattern="${LOG_PATTERN}"/>
            <Policies>
                <TimeBasedTriggeringPolicy interval="1"/>
                <SizeBasedTriggeringPolicy size="10MB"/>
            </Policies>
            <DefaultRolloverStrategy max="15"/>
        </RollingFile>
    </appenders>

    <loggers>
        <!-- 此处 定义到Mapper接口所在的包路径即可 也可指定某个文件的日志级别-->
        <logger name="com.shan.hero.admin.mapper" level="DEBUG" additivity="false">
            <AppenderRef ref="Console"/>
        </logger>
               
       <!-- 此处指定 整个的 日志级别 info -->
        <root level="info">
            <appender-ref ref="Console"/>
            <appender-ref ref="RollingFileInfo"/>
            <appender-ref ref="RollingFileError"/>
        </root>
    </loggers>
</configuration>
