Daniel Kulp reassigned CXF-4703:
--------------------------------
Assignee: Daniel Kulp
> CXF loading performance
> -----------------------
>
> Key: CXF-4703
> URL: https://issues.apache.org/jira/browse/CXF-4703
> Project: CXF
> Issue Type: Improvement
> Components: Bus
> Affects Versions: 2.7.0
> Environment: CXF with Spring on Tomcat server
> Reporter: E Chaplet
> Assignee: Daniel Kulp
> Labels: performance
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> Context : A lot of beans managed by Spring (more than 2500 beans) and about
> 120 endpoints managed by CXF
> The loading time of the 120 web services is approximately 4 minutes, too long
> for me !!
> I identified an area for improvement :
> * CXFBusImpl
> Slowness comes from getExtension(Class<T> extensionType) method
> => loc.getBeansOfType(ExtensionType);
> Here, Spring is looking for beans of a Class in his big context...
> Great, but if no beans are found, the next time this method is called with
> the same Class, this method is looking again in Spring beans (by
> getBeansOfType) !!!
> it can be easily improved by adding an emptyBeanExtensions Set which goal is
> to identify wich Class has no Spring beans.
> Exemple (I saved more than 1 minute loading time with this code):
> public final <T> T getExtension(Class<T> extensionType)
> {
> Object obj = extensions.get(extensionType);
> if (obj == null && !emptyExtensions.contains(extensionType))
> {
> ConfiguredBeanLocator loc = (ConfiguredBeanLocator)
> extensions.get(ConfiguredBeanLocator.class);
> if (loc == null)
> {
> loc = createConfiguredBeanLocator();
> }
> if (loc != null)
> {
> //force loading
> Collection<?> objs = loc.getBeansOfType(extensionType);
> if (objs != null)
> {
> if (objs.isEmpty())
> {
> emptyExtensions.add(extensionType);
> }
> else
> {
> for (Object o : objs)
> {
> extensions.put(extensionType, o);
> }
> obj = extensions.get(extensionType);
> }
> }
> }
> }
> if (null != obj)
> {
> return extensionType.cast(obj);
> }
> return null;
> }
