The Ehcache documentation focuses on XML declarative configuration. Programmatic Memory-Based Cache Sizing (Ehcache and higher). Initially . Ehcache and higher does not allow multiple CacheManagers with the same See the Ehcache API documentation for more information on these methods. Documentation Ehcache is an open source, standards-based cache that boosts performance, This version of Ehcache increases on-heap performance.

If the Caches under management use only the MemoryStore, there are no special considerations. Setting this system property to true using java -Dnet. Additional caches may be configured with different configurations, or even implementations. By default, all Ehcache operations are blocking, and async implementations will block threads in the default execution context.

Ehcache is redistributed by many projects, some of which might not provide an up-to-date sample Ehcache XML configuration file. If there are, a CacheException is thrown. While a defaultCache configuration is not required, an error is generated if caches are created by name programmatically with no defaultCache loaded. This makes it very easy to start with caching Objects and then change your Objects to Seralizable to participate in the extra features when dcumentation.

Pinning of caches or specific elements is discussed in Pinning, Expiration, and Eviction. This documentatiln shows how to dynamically modify the cache configuration of a running cache:. When rocumentation cache starts up, the stores are always empty. The two types will coexist peacefully. If the named or default unnamed Socumentation does not exist, the CacheManager.


Key Classes and Methods Introduction.

By default, Play will try to create these caches for you. You can provide your own implementation of net. If so, download Ehcache. The default implementation uses serialization to copy elements.

The element expires at this limit and will no longer be returned from the cache. Caches can be configured in Ehcache either declaratively in XML, or by creating caches programmatically and specifying their parameters in the constructor.

The APIs are identical except for the return methods from Element.

Grails Plugin: Ehcache Cache Plugin

After reading the documentation guidelinesplease feel free to contribute a docmentation request. Cache elements are stored in the MemoryStore. The maximum number of seconds an element can exist in the cache regardless of use. Caches consume memory, and disk space. To disable the check, do one of the following:. Each CacheManager requires its own configuration.

Cache Configuration

This philosophy is one of the fundamentals behind Play, and is different from Java EE, where the session is expected to retain values throughout its lifetime. For example, the following is the JGroups bootstrap cache loader:. The update checker docuemntation used to see if you have the latest version of Ehcache.

CacheManager to the default provider, add the following to your dependencies list:. Note that some elements documented by the Ehcache XML schema pertain only to BigMemory and are not valid for the open-source version of Ehcache.


CacheManager supports two creation modes: To get the full Ehcache implementation, add ehcache to your dependencies list:. To provide an implementation of docu,entation cache API in addition to the default implementation, you can either create a custom qualifier, or reuse the NamedCache qualifier to bind the implementation. This is provided for ease of migration. While both approaches are fully supported, it is generally a good idea to separate the cache configuration from runtime use.

If that is the case, you can throw an UnsupportedOperationException in the removeAll method. Creation of, access to, and removal of caches is controlled by the CacheManager.


All caches implement the Ehcache interface. You can see the total effect in a configuration file. Replicated caches provide a bootstrap mechanism that populates them. Therefore, each time new CacheManager Ehcache will attempt to docujentation conflicts and will emit a warning reminding the user to configure a separate configuration for multiple CacheManagers with conflicting settings. Each cache contains Elements.

The maximum number of seconds an element can exist in the cache without being accessed. The non-default creation methods allow a configuration file to be specified with any name you want. It is possible to provide a custom implementation of the cache API that either replaces, or sits along side the default implementation.
