springboot整合logback.xml(将sql日志输出到指定的日志文件中)

一.项目结构图

二,添加pom文件

<!--添加lomback-->
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.25</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-core</artifactId>
    <version>1.1.11</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.1.11</version>
</dependency>

三,添加mybatis-config.xml配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <!-- 全局参数 -->
    <settings>
        <!-- 打印sql语句-->
       <!-- <setting name="logImpl" value="STDOUT_LOGGING"/>-->

            <setting name="logPrefix" value="mybatis.sql."/>
            <!-- 打开延迟加载的全局开关 -->
            <setting name="lazyLoadingEnabled" value="true" />
            <setting name="aggressiveLazyLoading" value="false" />
            <setting name="mapUnderscoreToCamelCase" value="true" />
    </settings>
</configuration>

四,添加logback-spring.xml

<configuration>
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>INFO</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
        <encoder>
            <pattern>
                %-4relative [%thread] %-5level %logger{30} - %msg%n
            </pattern>
        </encoder>
    </appender>
    <appender name="MyBatis" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>logs/mybatis-sql.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
           <!-- <FileNamePattern>${LOG_HOME}/logs/mybatis-sql.log.%d{yyyy-MM-dd}</FileNamePattern>-->
            <FileNamePattern>logs/mybatis-sql.log.%d{yyyy-MM-dd}</FileNamePattern>
            <maxHistory>30</maxHistory>
        </rollingPolicy>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <pattern>%thread|%d{yyyy-MM-dd HH:mm:ss.SSS}|%level|%logger{36}|%m%n</pattern>
        </encoder>
    </appender>

    <logger name="mybatis.sql" level="DEBUG">
        <appender-ref ref="MyBatis"/>
    </logger>
    <root level="DEBUG">
        <appender-ref ref="CONSOLE" />
    </root>
</configuration>
