8.6. Multiple Caching Providers
Caching providers are obtained from
javax.cache.Caching using the overloaded getCachingProvider() method; by default this method will attempt to load any META-INF/services/javax.cache.spi.CachingProvider files found in the classpath. If one is found it will determine the caching provider in use.
With multiple caching providers available a specific provider may be selected using either of the following methods:
getCachingProvider(ClassLoader classLoader)getCachingProvider(String fullyQualifiedClassName)
To switch between caching providers ensure that the appropriate provider is available in the default classpath, or select it using one of the above methods.
All
javax.cache.spi.CachingProviders that are detected or have been loaded by the Caching class are maintained in an internal registry, and subsequent requests for the same caching provider will be returned from this registry instead of being reloaded or reinstantiating the caching provider implementation. To view the current caching providers either of the following methods may be used:
getCachingProviders()- provides a list of caching providers in the default class loader.getCachingProviders(ClassLoader classLoader)- provides a list of caching providers in the specified class loader.
