This annotation indicates that the result of a

method invocation should be cached so that

subsequent invocations with the same

arguments can return the result from the

cache.

1. Before the method execution, Spring

generates a cache key based on the

method arguments and the specified

cache name.

2. Spring checks if the cache contains a

value associated with the generated

cache key.

3. If a cached value is found, it is returned

directly, and the method is not executed.

4. The method is executed if no cached

value is found, and the result is stored in

the cache with the generated key.

5. The result of the method is returned to the

caller.
