Class PerformanceMonitorFilter

java.lang.Object

org.fishwife.jrugged.PerformanceMonitor

org.fishwife.jrugged.spring.PerformanceMonitorBean

org.fishwife.jrugged.spring.PerformanceMonitorFilter

All Implemented Interfaces:

javax.servlet.Filter, ServiceWrapper

@ManagedResource
public class PerformanceMonitorFilter
extends PerformanceMonitorBean
implements javax.servlet.Filter

This class is a standard Servlet filter that can be configured in web.xml to wrap all request handling in a PerformanceMonitor. In order to get useful access to the statistics, however, it is most convenient to make use of Spring's DelegatingFilterProxy in web.xml and instantiate this filter within a Spring application context. This will allow the JMX annotations inherited from PerformanceMonitorBean to take effect, with the result that you can get a high-level performance monitor wrapped around all of your application's request handling.
