Chris Beams 91f05c8b9d Avoid creation of unnecessary Environment objects Prior to this change, any instantiation of an AnnotationConfigApplicationContext would trigger the creation of three StandardEnvironment objects: one for the ApplicationContext, one for the AnnotatedBeanDefinitionReader, and one for the ClassPathBeanDefinitionScanner. The latter two are immediately swapped out when the ApplicationContext delegates its environment to these subordinate objects anyway. Not only is it inefficient to create these two extra Environments, it creates confusion when debug-level logging is turned on. From the user's perspective and in practice, there is only one Environment; logging should reflect that. This change ensures that only one Environment object is ever created for a given ApplicationContext. If an AnnotatedBeanDefinitionReader or ClassPathBeanDefinitionScanner are used in isolation, e.g. against a plain BeanFactory/BeanDefinitionRegistry, then they will still create their own local StandardEnvironment object. All public API compatibility is preserved; new constructors have been added where necessary to accommodate passing an Environment directly to ABDR ar CPBDS.		13 years ago
