Spring HazelcastCacheManager, Accessing Hazelcast instance

In my Spring boot app, we have configured @EnableCaching with HazelcastCacheManager and it working without problem.

But, it is required to access Hazelcast instance to use it's other features (distributed locks, distributed computing).

How can I achieve this using the same instance of Hazelcast used in HazelcastCacheManager (instead of creating new one)?

p.s. First thing came to my mind is registering Hazelcast wrapper class as @Component, and Auto wiring it to @Configuration annotated class using constructor. But I am not sure how things will turn out.

Solution

  • How about this, HazelcastCacheManager.getHazelcastInstance().

    Perhaps also then expose the retrieved HazelcastInstance as a @Bean, then you can inject into the rest of your application and that code need have no awareness of @EnabledCaching being present or absent.
