Interface CacheManager

  • All Known Implementing Classes:
    CacheManagerImpl
    public interface CacheManager

    Use this interface to retrieve all existing Cache names and interact with any cache programmatically e.g. store, retrieve or delete cache values. It shares the same caches collection the Quarkus caching annotations use. The CacheName annotation can also be used to inject and access a specific cache from its name.

    Code example: 

     @ApplicationScoped
 public class CachedService {

     @Inject
     CacheManager cacheManager;

     String getExpensiveValue(Object key) {
         Cache cache = cacheManager.getCache("my-cache");
         Uni<String> cacheValue = cache.get(key, () -> expensiveService.getValue(key));
         return cacheValue.await().indefinitely();
     }
 }
