org.springframework.expression.spel.support.ReflectivePropertyAccessor
An optimized form of a PropertyAccessor that will use reflection but only knows how to access a particular property on a particular class. This is unlike the general ReflectivePropertyResolver which manages a cache of methods/fields that may be invoked to access different properties on different classes. This optimal accessor exists because looking up the appropriate reflective object by class/name on each read is not cheap.

    ExtensionAwarePropertyAccessor accessor = new ExtensionAwarePropertyAccessor(getExtensions());


    ec.addPropertyAccessor(accessor);
    ec.addPropertyAccessor(new ReflectivePropertyAccessor());
    ec.addMethodResolver(accessor);


    // Add parameters for indexed access
    ec.setRootObject(parameterValues);
    ec.setVariables(collectVariables(parameters, parameterValues));
