Srping监听Controller,Service,Dao 方法执行时间场景 http://my.oschina.net/guoenzhou/blog/738410
可能碰到依赖循环问题： http://www.mekau.com/index.php/tec/server/spring/pandy_3667.html
1.applicationContext.xml配置
beanNames根据注入实例名称来过滤拦截
interceptorNames 配置了具体拦截器实例Bean id

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
<?xml version="1.0" encoding="UTF-8"?> <beans> <bean id="daoProxyCreator" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"> <property name="interceptorNames"> <list> <value>performanceInterceptor</value> </list> </property> <property name="beanNames"> <list> <value>*Dao</value> <value>*Controller</value> <value>*Service</value> </list> </property> </bean> <bean id="performanceInterceptor"class="com..PerformanceInstrumentInterceptor"> <property name="threshold" value="200"/> </bean> </beans> |
2.监听执行时间拦截器
拦截器类实现MethodInterceptor
threshold为超时阀值，超过这个阀值日志打印出来
