8.5. Clustering JCache instances
8.5. Clustering JCache instances JBoss Data Grid implementation goes beyond the specification in order to provide the possibility to cluster caches using the standard API. Given a configuration file to replicate caches such as: It is possible to create a cluster of caches using this code: Report a bug
<namedCache name="namedCache"> <clustering mode="replication"/> </namedCache> import javax.cache.*; import java.net.URI; // For multiple cache managers to be constructed with the standard JCache API // and live in the same JVM, either their names, or their classloaders, must // be different. // This example shows how to force their classloaders to be different. // An alternative method would have been to duplicate the XML file and give // it a different name, but this results in unnecessary file duplication. ClassLoader tccl = Thread.currentThread().getContextClassLoader(); CacheManager cacheManager1 = Caching.getCachingProvider().getCacheManager( URI.create("infinispan-jcache-cluster.xml"), new TestClassLoader(tccl)); CacheManager cacheManager2 = Caching.getCachingProvider().getCacheManager( URI.create("infinispan-jcache-cluster.xml"), new TestClassLoader(tccl)); Cache<String, String> cache1 = cacheManager1.getCache("namedCache"); Cache<String, String> cache2 = cacheManager2.getCache("namedCache"); cache1.put("hello", "world"); String value = cache2.get("hello"); // Returns "world" if clustering is working // -- public static class TestClassLoader extends ClassLoader { public TestClassLoader(ClassLoader parent) { super(parent); } }
