SpringBoot整合logback日志框架

在resource下创建一个名称为 logback-spring.xml文件

<configuration>

      <!--日志文件夹存放的名称-->
    <contextName>demo-test</contextName>

    <!--各项目日志保存统一父目录->路径自己设置绝对路径和相对路径都可以-->
    <property name="LOG_DIR" value="./log/" />
    <!--最大保存天数-->
    <property name="KEEP_MAX_DAY" value="180" />
    <!--总最大保存文件大小-->
    <property name="KEEP_TOTAL_MAX_SIZE" value="5GB" />
    <!--单文件最大保存文件大小-->
    <property name="KEEP_FILE_MAX_SIZE" value="100MB" />

    <!--输出到控制台-->
    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
        </encoder>
    </appender>

    <!--输出到ERROR事件记录文件-->
    <appender name="errorFile" class="ch.qos.logback.core.rolling.RollingFileAppender">

        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>ERROR</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>

        <file>${LOG_DIR}/${CONTEXT_NAME}/error/${CONTEXT_NAME}-error.log</file>

        <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
            <fileNamePattern>${LOG_DIR}/${CONTEXT_NAME}/error/${CONTEXT_NAME}-error-%d{yyyy-MM-dd}.%i.log.gz</fileNamePattern>
            <maxFileSize>${KEEP_FILE_MAX_SIZE}</maxFileSize>
            <maxHistory>${KEEP_MAX_DAY}</maxHistory>
            <totalSizeCap>${KEEP_TOTAL_MAX_SIZE}</totalSizeCap>
        </rollingPolicy>

        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
        </encoder>

    </appender>

    <!--输出到WARN事件记录文件-->
    <appender name="warnFile" class="ch.qos.logback.core.rolling.RollingFileAppender">

        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>WARN</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>

        <file>${LOG_DIR}/${CONTEXT_NAME}/warn/${CONTEXT_NAME}-warn.log</file>

        <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
            <fileNamePattern>${LOG_DIR}/${CONTEXT_NAME}/warn/${CONTEXT_NAME}-warn-%d{yyyy-MM-dd}.%i.log.gz</fileNamePattern>
            <maxFileSize>${KEEP_FILE_MAX_SIZE}</maxFileSize>
            <maxHistory>${KEEP_MAX_DAY}</maxHistory>
            <totalSizeCap>${KEEP_TOTAL_MAX_SIZE}</totalSizeCap>

        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
        </encoder>

    </appender>

    <!--输出到INFO事件记录文件-->
    <appender name="infoFile" class="ch.qos.logback.core.rolling.RollingFileAppender">

        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>INFO</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>

        <file>${LOG_DIR}/${CONTEXT_NAME}/info/${CONTEXT_NAME}-info.log</file>

        <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
            <fileNamePattern>${LOG_DIR}/${CONTEXT_NAME}/info/${CONTEXT_NAME}-info-%d{yyyy-MM-dd}.%i.log.gz</fileNamePattern>
            <maxFileSize>${KEEP_FILE_MAX_SIZE}</maxFileSize>
            <maxHistory>${KEEP_MAX_DAY}</maxHistory>
            <totalSizeCap>${KEEP_TOTAL_MAX_SIZE}</totalSizeCap>
        </rollingPolicy>

        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
        </encoder>

    </appender>

    <logger name="org.springframework.jdbc.core" level="debug" additivity="false">
        <appender-ref ref="console" />
    </logger>

    <logger name="com.springboot.web.dynamic_debug" level="debug" additivity="false">
        <appender-ref ref="console" />
    </logger>

    <root level="info">
        <appender-ref ref="console" />
        <appender-ref ref="errorFile" />
        <appender-ref ref="warnFile" />
        <appender-ref ref="infoFile" />
    </root>

</configuration>

然后yml配置添加

logging:
  config: classpath:logback-spring.xml
  level:
    com.example.demotest.*: debug

com.example.demotest.* 这个是项目的包名 根据自己实际的来

然后启动就可以了
