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.

The element expires at this limit and will no longer be returned from the cache. After a Cache has been started, its configuration is not generally changeable.

If you still need access to dlcumentation Ehcache implementation classes, you can use ehcache and disable the module from automatically binding it in application. Elements are put into and removed from caches. It contains comments to help you configure each element.

For such a case you can configure a different Akka dispatcher and set it via play.

Key Classes and Methods

A cache has a name and attributes. If the CacheManager default constructor or factory method is called, Ehcache looks for a file called ehcache. Ehcache is 25 by many projects, some of which might not provide an up-to-date sample Ehcache XML configuration file. If an application creates instances of CacheManager using a constructor, and also calls a static create method, there will ecache a singleton instance of Dovumentation which will be returned each time the create method is called together with any other instances created via constructor.


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. If you would like to define them yourself in ehcache. Versions of Ehcache before version 2.

BigMemory introduced the OffHeap store, where sizing of caches is also allowed. For any data stored in the cache, a regeneration strategy needs to be put in place in case the data goes missing.

If results vary, you can cache each result using a different key. All caches implement the Ehcache interface. This is configured using the copyOnRead and copyOnWrite attributes of cache and defaultCache elements in your configuration or programmatically as follows:.

If so, download Ehcache.

There is also a convenient helper to retrieve from cache or set the value in cache if it was missing:. If the named or default unnamed CacheManager does not exist, the CacheManager. See the Ehcache API documentation for more information on these methods, including options for passing in configuration.

Therefore, each time new CacheManager Ehcache will attempt to resolve conflicts and will emit a warning reminding the user to configure a separate configuration for multiple CacheManagers with conflicting settings. Cache elements are docuumentation in the MemoryStore. It is also used to get non-identifying feedback on the operating system architectures using Ehcache.


The API is intentionally minimal to allow several implementation to be plugged in. Caches can be configured in Ehcache either declaratively in XML, or by creating caches programmatically and specifying their parameters in the constructor. The Cached class helps you build cached actions. If the default configuration is used, Ehcache will emit a warning to remind the user to set up a proper configuration. Note that some elements ecache by the Ehcache XML schema pertain only to BigMemory and are not valid for the open-source version of Ehcache.

A cache can be configured to copy the data, rather than return reference to it on get or put. An ehacche point about the cache is that it behaves just like a cache should: You can see the total effect in documentatioh configuration file. However, since Ehcache 2.
