使用Spring3.0的AOP结合log4j实现接口方法执行时间记录

2015-06-01 09:54 1001 查看
项目使用RPC提供的内部服务,需要监控每个接口方法的调用情况以及响应时间,如果接口方法开始和结束时都计时并将两个时间相减得到响应时间,势必对代码的入侵太大。使用AOP刚好能很优雅的解决这个问题!

1.log4j的配置log4j.xml。这里使用xml风格的配置

<appender name="info-out" class="org.apache.log4j.DailyRollingFileAppender">
<param name="File" value="/data/logs/hiluo-service/info.log" />
<param name="DatePattern" value="'.'yyyy-MM-dd'.log'" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{yyyy.MM.dd HH:mm:ss} [%C{1}:%M] %m%n" />
</layout>
<filter class="org.apache.log4j.varia.LevelRangeFilter">
<param name="LevelMax" value="info" />
<param name="LevelMin" value="info" />
<param name="AcceptOnMatch" value="true" />
</filter>
</appender>


log4j的配置参见:http://stonexmx.blog.163.com/blog/static/1221585872009716112428738/

PatternLayout输出格式参见:http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html

value="%d{yyyy.MM.dd HH:mm:ss} [%C{1}:%M] %m%n",%C{1}-类名,如果使用%C将输出类的全路径名,%M-方法名

输出类似以下内容:



2.MethodTimeAdvice.java 用来记录时间

package yourpackage.utils;

import org.aopalliance.intercept.MethodInterceptor;
import org.aopalliance.intercept.MethodInvocation;
import org.apache.commons.lang.StringUtils;
import org.apache.commons.lang.time.StopWatch;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class MethodTimeAdvice implements MethodInterceptor {

private static final Logger Log = LoggerFactory
.getLogger(MethodTimeAdvice.class);

@Override
public Object invoke(MethodInvocation invocation) throws Throwable {
// 用 commons-lang 提供的 StopWatch 计时
StopWatch clock = new StopWatch();
clock.start(); // 计时开始
Object result = invocation.proceed();
clock.stop(); // 计时结束

// 方法参数类型,转换成简单类型
Class[] params = invocation.getMethod().getParameterTypes();
String[] simpleParams = new String[params.length];
for (int i = 0; i < params.length; i++) {
simpleParams[i] = params[i].getSimpleName();
}
Object[] args = invocation.getArguments();

Log.info("Takes:" + clock.getTime() + " ms ["
+ invocation.getThis().getClass().getName() + "."
+ invocation.getMethod().getName() + "("
+ StringUtils.join(simpleParams, ",") + ")("
+ StringUtils.join(args, ",") + ")] ");
return result;
}

}


3.applicationContext.xml

<?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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd" default-lazy-init="true">
<aop:aspectj-autoproxy />
<bean id="methodTimeAdvice" class="cn.hiluo.openfire.utils.MethodTimeAdvice" />
<aop:config>
<!-- 用 AspectJ 的语法定义 Pointcut,这里拦截 service 包中的所有方法 -->
<aop:advisor id="methodTimeLog" advice-ref="methodTimeAdvice"
pointcut="execution(* yourpackage.service.impl..*.*(..))" />
</aop:config>
<bean id="yourservice" class="**.impl.yourServiceImpl">

</bean>
。。。。。yourbeans
</beans>


4.注意需要加入Spring相关包,比较容易遗漏的:org.springframework.aop-3.0.6.RELEASE.jar,org.springframework.aspects-3.0.6.RELEASE.jar,aspectjweaver-1.5.3.jar,aopalliance-1.0.jar

5.applicationContext.xml注意xml中和AOP相关的dtd的引入,还要注意pointcut="execution(* yourpackage.service.impl..*.*(..))" 的配置语法

6.最后在info.log里面可以看到如上图的输出,最后再用shell统计即可。
