logback 三

一.LoggerFactory.gerLogger()使用：
　　private Logger vitalLogger= LoggerFactory.getLogger("vitalRequest");
　　如果为字符串 则需要在logback.xml中配置

　　<logger name="vitalRequest" level="INFO" additivity="false">
  　　  <appender-ref ref="vitalRequestAppender"/>
　　</logger>
　　其中vitalRequestAppender则为上面所配置的Appender
具体如下：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>

    <property name="LOG_HOME" value="${CATALINA_BASE}/logs"/>

    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>INFO</level>
        </filter>
        <encoder>
            <pattern>[%d{yyyy-MM-dd HH:mm:ss.SSS}]WTraceId[%X{wtraceid}] %5p %logger{0}:%L] %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="accessAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_HOME}/request.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${LOG_HOME}/request.log.%d{yyyy-MM-dd}.gz</fileNamePattern>
        </rollingPolicy>
        <encoder>
            <pattern>[%d{yyyy-MM-dd HH:mm:ss.SSS}]WTraceId[%X{wtraceid}] %5p %logger{0}:%L] %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="requestAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_HOME}/cvs.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${LOG_HOME}/cvs.log.%d{yyyy-MM-dd}.gz</fileNamePattern>
            <MaxHistory>15</MaxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>[%d{yyyy-MM-dd HH:mm:ss.SSS}]WTraceId[%X{wtraceid}] %5p %logger{0}:%L] %msg%n</pattern>
        </encoder>
    </appender>

    <!--关键信息导出文件-->
    <appender name="vitalRequestAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_HOME}/vitalRequest.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <fileNamePattern>${LOG_HOME}/vitalRequest.log.%d{yyyy-MM-dd}.gz</fileNamePattern>
        </rollingPolicy>
        <encoder>
            <pattern>[%d{yyyy-MM-dd HH:mm:ss.SSS}]WTraceId[%X{wtraceid}] %5p %logger{0}:%L] %msg%n</pattern>
        </encoder>
    </appender>

    <logger name="accessDataLog" level="INFO" additivity="false">
        <appender-ref ref="accessAppender"/>
    </logger>

    <logger name="com.wormpex.inf.wmq.rabbit.consumer.RapidMQMessageListenerAdapter" level="DEBUG" additivity="false">
        <appender-ref ref="console" />
    </logger>

    <logger name="vitalRequest" level="INFO" additivity="false">
        <appender-ref ref="vitalRequestAppender"/>
    </logger>

    <logger name="com.wormpex.fd.trace.handler.LoggerAlarmHandler" level="ERROR" additivity="false" />

    <root level="INFO">
        <appender-ref ref="console"/>
        <appender-ref ref="requestAppender"/>
    </root>

</configuration>

如logback前两个文章所说 层级配置，及向指定文件输出日志内容。
