------------------------------
Summary: 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
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;
}
