今天將perf4j基于spring aop方式進入了接入，接入方法還是比較簡單。具體配置如下：
logback.xml

<!--perf4j配置-->
    <appender name="statistics" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <Encoding>UTF-8</Encoding>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--日志文件輸出的文件名 -->
            <FileNamePattern>logs/statistics.%d{yyyy-MM-dd}.log</FileNamePattern>
        </rollingPolicy>
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>%msg%n</pattern>
        </layout>
    </appender>

    <appender name="coalescingStatistics" class="org.perf4j.logback.AsyncCoalescingStatisticsAppender">
        <timeSlice>10000</timeSlice>
        <appender-ref ref="statistics"/>
    </appender>

    <logger name="org.perf4j.TimingLogger" level="info" additivity="false">
        <appender-ref ref="coalescingStatistics" />
    </logger>
<!--perf4j配置結束-->

aop.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
        http://www.springframework.org/schema/aop
     http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">

    <aop:config>
        <aop:aspect id="aspect" ref="timingAspect">
            <aop:pointcut id="timingCut" expression="execution(* com.xxx..*.*(..)) and @annotation(profiled))"/>
            <aop:around pointcut-ref="timingCut" method="doPerfLogging"/>
        </aop:aspect>
    </aop:config>
    <bean id="timingAspect" class="org.perf4j.slf4j.aop.TimingAspect" />
</beans>

當然還有更方便的配置方式

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">
    <aop:aspectj-autoproxy />

    <bean id="timingAspect" class="org.perf4j.slf4j.aop.TimingAspect" />
</beans>
