Hi,
I'm optimizing render response on a large view (takes over 3 secs to
render) and below you can see results of unsorted and unfiltered
ELResolvers chain. The most important info is that BeanELResolver
resolves property over 40000x from 64000 invocations. The second place
belongs to ImplicitObjectResolver with over 20000 resolved properties.
The reason why BeanElResolver is so successful is because majority of
expressions looks like
{requestScope.pojoObject.propertyOne.propertyTwo}.
The obvious optimalization would be move the BeanELResolver to top. But
you cannot: EL spec 2.2 javax.el.BeanELResolver: "If the property is not
found or is not readable, a PropertyNotFoundException is thrown." So
UEL spec. mandates that BeanELResolver must be last one which resolves
not-null base and a property on that base.
Do you know the reason for that? Do you have any ideas how to move
BeanELResolver to top and avoid thousands of "empty" geValue
invocations?
Thanks,
Kočičák
