Getting Spring Application Context- Stack Overflow

Java PingBook 2 months ago (10-23) 15 0

Question

Is there a way to statically/globally request a copy of the ApplicationContext in a Spring application?

Assuming the main class starts up and initializes the application context, does it need to pass that down through the call stack to any classes that need it, or is there a way for a class to ask for the previously created context? (Which I assume has to be a singleton?)

Answer

If the object that needs access to the container is a bean in the container, just implement the BeanFactoryAware or ApplicationContextAware interfaces.

If an object outside the container needs access to the container, I’ve used a standard GoF singleton pattern for the spring container. That way, you only have one singleton in your application, the rest are all singleton beans in the container.
