Chris Beams 7b999c676f Introduce ReflectionUtils#getUniqueDeclaredMethods This change is in support of certain polymorphism cases in @Configuration class inheritance hierarchies. Consider the following scenario: @Configuration public abstract class AbstractConfig { public abstract Object bean(); } @Configuration public class ConcreteConfig { @Override @Bean public BeanPostProcessor bean() { ... } } ConcreteConfig overrides AbstractConfig's #bean() method with a covariant return type, in this case returning an object of type BeanPostProcessor. It is critically important that the container is able to detect the return type of ConcreteConfig#bean() in order to instantiate the BPP at the right point in the lifecycle. Prior to this change, the container could not do this. AbstractAutowireCapableBeanFactory#getTypeForFactoryMethod called ReflectionUtils#getAllDeclaredMethods, which returned Method objects for both the Object and BeanPostProcessor signatures of the #bean() method. This confused the implementation sufficiently as not to choose a type for the factory method at all. This means that the BPP never gets detected as a BPP. The new method being introduced here, #getUniqueDeclaredMethods, takes covariant return types into account, and filters out duplicates, favoring the most specific / narrow return type. Additionally, it filters out any CGLIB 'rewritten' methods, which is important in the case of @Configuration classes, which are enhanced by CGLIB. See the implementation for further details.		15 years ago
