Package io.quarkus.cache

Interface CacheManager

  • 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 @io.quarkus.cache.CacheName annotation can also be used to inject and access a specific cache from its name.

    Code example: 

     @Singleton
 public class CachedService {

     private final CacheManager cacheManager;

     public CachedService(CacheManager cacheManager) {
         this.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();
     }
 }
