Class MemoryConstrainedCacheManager
java.lang.Object
org.apache.shiro.cache.AbstractCacheManager
org.apache.shiro.cache.MemoryConstrainedCacheManager
- All Implemented Interfaces:
- CacheManager, Destroyable
public class MemoryConstrainedCacheManager
- extends AbstractCacheManager
Simple memory-only based CacheManager
implementation usable in production
environments. It will not cause memory leaks as it produces Cache
s backed by
SoftHashMap
s which auto-size themselves based on the runtime environment's memory
limitations and garbage collection behavior.
While the Cache
instances created are thread-safe, they do not offer any enterprise-level features such as
cache coherency, optimistic locking, failover or other similar features. For more enterprise features, consider
using a different CacheManager
implementation backed by an enterprise-grade caching product (EhCache,
TerraCotta, Coherence, GigaSpaces, etc, etc).
