spring2.5 配置Perf4J

  1> 创建spring aop 拦截器:

 package com.core.perf4j.interceptor;import java.lang.reflect.Method;import java.util.Arrays;import java.util.HashMap;import java.util.Map;import org.perf4j.StopWatch;import org.perf4j.slf4j.Slf4JStopWatch;import org.springframework.aop.AfterReturningAdvice;import org.springframework.aop.MethodBeforeAdvice;public class Perf4jInterceptor implements MethodBeforeAdvice,AfterReturningAdvice {private Map<String, StopWatch> stopWatchMap = new HashMap<String, StopWatch>();public void before(Method method, Object[] args, Object targetObject)throws Throwable {String completeMethodName = this.getCompleteMethodNameByTarget(targetObject, method);// 创建性能测试日志StopWatch stopWatch;if (stopWatchMap.containsKey(completeMethodName)) {stopWatch = stopWatchMap.get(completeMethodName);stopWatch.start();} else {stopWatch = new Slf4JStopWatch(completeMethodName, Arrays.toString(args));stopWatchMap.put(completeMethodName, stopWatch);}}public void afterReturning(Object returnValue, Method method,Object[] args, Object target) throws Throwable {String completeMethodName = this.getCompleteMethodNameByTarget(target, method);if (stopWatchMap.containsKey(completeMethodName)) {StopWatch stopWatch = stopWatchMap.get(completeMethodName);stopWatch.stop();}}/** * * <p>Description: 根据目标对象与方法获取方法完整名称. </p> * * @param target * 目标对象 * <p> * @param method * 方法 * <p> * @return String 方法完整名称 */private String getCompleteMethodNameByTarget(Object targetObject, Method method) {String className = "";if (targetObject != null) {className = targetObject.toString();int index = className.indexOf("@");if (index >= 0) {className = className.substring(0, index);}}return className + "." + method.getName();}}

 

2>创建spring applicationContext-perf4j.xml配置文件:

<?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"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"default-autowire="byName"><bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"> <property name="beanNames"> <list><value>*Service</value></list> </property> <property name="interceptorNames"> <list><value>perf4jInterceptor</value></list> </property></bean> <bean name="perf4jInterceptor" class="com.core.perf4j.interceptor.Perf4jInterceptor" /></beans>

3> 日志配置:

log4j.rootLogger=info, stdout, logfile,graphExecutionTimes,graphExecutionTPS#输出到控制台log4j.appender.stdout=org.apache.log4j.ConsoleAppender#设置输出样式 log4j.appender.stdout.layout=org.apache.log4j.PatternLayout#自定义样式 log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%nlog4j.logger.org.springframework=DEBUGlog4j.logger.org.hibernate=DEBUGlog4j.appender.logfile=org.apache.log4j.RollingFileAppenderlog4j.appender.logfile.File=flex.log#log4j.appender.logfile.File=c:/jwzh.loglog4j.appender.logfile.MaxFileSize=512KB# Keep three backup files.log4j.appender.logfile.MaxBackupIndex=5log4j.appender.logfile.Append=true# Pattern to output: date priority [category] - messagelog4j.appender.logfile.layout=org.apache.log4j.PatternLayoutlog4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%nlog4j.logger.org.perf4j.TimingLogger=info#perf4j#输出到控制台#log4j.appender.graphExecutionTimes=org.apache.log4j.ConsoleAppender#设置输出样式 #log4j.appender.graphExecutionTimes.layout=org.apache.log4j.PatternLayout#自定义样式 #log4j.appender.graphExecutionTimes.layout.ConversionPattern=%d %p [%c/:%L] - %m%n#log4j.appender.graphExecutionTimes=org.perf4j.log4j.GraphingStatisticsAppender#log4j.appender.graphExecutionTimes.File=perfStats.log#perf4j#输出到控制台#log4j.appender.graphExecutionTPS=org.apache.log4j.ConsoleAppender#设置输出样式 #log4j.appender.graphExecutionTPS.layout=org.apache.log4j.PatternLayout#自定义样式 #log4j.appender.graphExecutionTPS.layout.ConversionPattern=%d %p [%c/:%L] - %m%n#log4j.appender.graphExecutionTPS=org.perf4j.log4j.GraphingStatisticsAppender#log4j.appender.graphExecutionTPS.File=perfGraphs.log

 

4>控制台输出:

2735 [main] INFO org.perf4j.TimingLogger - start[1263281429349] time[579] tag[test.KwCodeServiceImpl.findAll] message[[]]
