Class IntrospectionELResolver

java.lang.Object

jakarta.el.ELResolver

io.micronaut.el.resolver.IntrospectionELResolver

@Internal
public final class IntrospectionELResolver
extends jakarta.el.ELResolver

The ELResolver resolving the types annotated with Introspected through the bean introspection generated for them at compilation time.

The properties are read and written through the generated BeanIntrospection, so no reflection is used. The methods annotated with io.micronaut.context.annotation.Executable are invoked the same way; the other methods are left to the rest of the chain. A type without an introspection is left unresolved, so that the standard resolvers of the specification can handle it.
