spring boot日志配置+mybatis输出SQL

spring boot日志配置+mybatis输出SQL

因为项目使用的logback，这里以Logback进行说明。

其实要在日志中输出SQL，只需要加一行配置即可：

<logger name="mapper所在的包名" level="DEBUG">logger>

将mapper所在包的日志级别设置为debug即可。

下面贴一个完整的logback的配置：

<configuration>
    
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d %p (%file:%line\)- %m%npattern>
            <charset>GBKcharset>
        encoder>
    appender>
    <appender name="baselog"
              class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>log/base.logFile>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>log/base.log.%d.%ifileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                
                <maxFileSize>64 MBmaxFileSize>
            timeBasedFileNamingAndTriggeringPolicy>
        rollingPolicy>
        <encoder>
            <pattern>
                %d %p (%file:%line\)- %m%n
            pattern>
            <charset>UTF-8charset>
            
        encoder>
    appender>
    <root level="info">
        <appender-ref ref="STDOUT"/>
    root>
    <logger name="com.ybf" level="DEBUG">
        <appender-ref ref="baselog"/>
    logger>
    <logger name="com.sample.activity.web.mapper" level="DEBUG">
        <appender-ref ref="STDOUT" />
    logger>
configuration>
