Caching

We are using Hazelcast for caching

By annotating the method using the @Cacheable annotation the result of the subsequent invocations will be cached. The @CacheEvict(allEntries=true) clears all the entries from the cache.

@Cachable

Is used to adding the cache behavior to a method. We can also give the name to it, where the cache results would be saved.

@CacheEvict

Is used to remove the one or more cached values. allEntries=true parameter allows us to remove all entries from the cache.

@CachePut

Is used to update the cached value. Creating an Item model

Usage Example

    @Cacheable(value="itemCache", key="#id")
    public Item getItem(int id){
    }

    @CacheEvict(value="itemCache",key = "#id")
    public int deleteItem(int id){
    }

    @CachePut(value="itemCache")
    public void updateItem(Item item){
    }
