Which two statements about BeanFactoryPostProcessors are true? (Choose two.)
BeanFactoryPostProcessors in Spring allow for the transformation of Spring bean definitions before the beans are instantiated, which helps in modifying or adding properties to bean definitions at runtime. This is a crucial capability for intercepting the bean creation process and customizing bean configurations. Furthermore, PropertySourcesPlaceholderConfigurer, which implements BeanFactoryPostProcessor, is used to read property values from the Spring Environment, making it essential for externalized configuration. This ensures that values can be dynamically injected into bean definitions, enhancing the flexibility and manageability of application configurations.
