打印系统的性能分析日志，香港服务器，用于分析系统性能
一.maven依赖
<dependency><groupId>com.duowan.common</groupId><artifactId>duowan-common-log</artifactId><version>1.0.5</version></dependency><dependency><groupId>com.duowan.common</groupId><artifactId>duowan-common-util</artifactId><version>1.0.8</version></dependency>
二.配置
1.web.xml filter配置
拦截需要性能分析的URL,被拦截的方法启动子任务分析:start(requestURI),release()
<!– Profiler性能分析Filter –><filter><filter-name>ProfilerLoggerFilter</filter-name><filter-class>com.duowan.common.log.filter.ProfilerLoggerFilter</filter-class></filter><filter-mapping><filter-name>ProfilerLoggerFilter</filter-name><url-pattern>*.do</url-pattern></filter-mapping>
顺德
2.spring方法拦截器配置
拦截需要性能分析的方法及类,被拦截的方法启动子任务分析:enter(),release()
<bean/><!– 拦截有@Profiled标注的类或者方法 –><bean><property value=”true”/><property><value>profiledAnnotationPointcutAdvisor</value></property><property><list><value>userGameServerDao</value><value>userGameServerService</value></list></property></bean>
三.日志打印结果
1. 日志打印位置
# DWPROJECTNO是环境变量中的配置，香港服务器，profilerLogDir整个配置可以通过System.properties覆盖profilerLogDir=/data2/log/${DWPROJECTNO}/
2. digest-profiler.log
#动作时间，耗时(单位毫秒)，动作ID，成功标志(Y为成功，其它为错误)，美国服务器，循环执行次数(loopCount),方法执行结果(resultSize),clientIp2012-10-16 00:06:20.586,0,UserGameServerBatchCallback|userDataBatchUpdater.init|saveUserGameServerList,Y,1,0,2012-10-16 00:06:20.591,0,UserGameServerBatchCallback|userDataBatchUpdater.init|saveUserGameServerList,Y,1,0,2012-10-16 00:06:20.613,0,UserGameServerBatchCallback|userDataBatchUpdater.init|saveUserGameServerList,Y,10,0,2012-10-16 00:06:20.63,1,UserGameServerBatchCallback|userDataBatchUpdater.init|saveUserGameServerList,Y,13,0,2012-10-16 00:06:20.642,0,UserGameServerBatchCallback|userDataBatchUpdater.init|saveUserGameServerList,Y,2,0,2012-10-16 00:06:20.659,1,UserGameServerBatchCallback|userDataBatchUpdater.init|saveUserGameServerList,Y,16,0,2012-10-16 00:06:20.696,0,UserGameServerBatchCallback|userDataBatchUpdater.init|saveUserGameServerList,Y,1,0,
3. dump-profiler.log

四. API使用
1.最简使用
切换行号显示;() {= .(= }..}未经一番寒彻骨，焉得梅花扑鼻香
