logback日誌使用方法

將 logback-spring.xml 放在resource目錄下
logback-spring.xml 文件配置如下

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <!--配置日誌輸出格式-->
    <!--將日誌輸出到控制檯-->
    <appender name="consoleLog"
              class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>
                %p - %d - %c - %msg%n
            </pattern>
        </layout>
    </appender>


    <!-- 配置debug級別日誌,實現分離文件日誌配置 -->
    <appender name="fileDebugLog"
              class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>DEBUG</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
        <encoder>
            <pattern>
                %d - %c- %msg%n
            </pattern>
            <charset>UTF-8</charset>
        </encoder>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${user.dir}/log/%d/debug.log</fileNamePattern>


        </rollingPolicy>
    </appender>

    <!--分離配置Info級別日誌-->
    <appender name="fileInfoLog" 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>
        <encoder>
            <pattern>
                %d - %c - %msg%n
            </pattern>
            <charset>UTF-8</charset>
        </encoder>
        <!--設置滾動策略  按時間策略來生成日誌-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--配置生成路徑-->
            <fileNamePattern>${user.dir}/log/%d/info.log</fileNamePattern>
        </rollingPolicy>
    </appender>


    <!--日誌分離需要用來過濾 filter-->
    <appender name="fileErrorLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>ERROR</level>
        </filter>
        <encoder>
            <pattern>
                %d - %c - %msg%n
            </pattern>
            <charset>UTF-8</charset>
        </encoder>
        <!--設置滾動策略  按時間策略來生成日誌-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--配置生成路徑-->
            <fileNamePattern>${user.dir}/log/%d/error.log</fileNamePattern>
        </rollingPolicy>
    </appender>

    <!-- 配置項用處,設置這個項目下,日誌級別爲debug (引用一上日誌配置)  -->
    <root level="info">
        <appender-ref ref="fileInfoLog"/>
        <appender-ref ref="fileErrorLog"/>
        <appender-ref ref="fileDebugLog"/>
        <appender-ref ref="consoleLog"/>
    </root>
</configuration>

日誌輸出目錄如下圖，目錄格式可根據自己的需求自定義配置
