17.3. Callable and CDI
17.3. Callable and CDI Where DistributedCallable cannot be implemented or is not appropriate, and a reference to input cache used in DistributedExecutorService is still required, there is an option to inject the input cache by CDI mechanism. When the Callable task arrives at a Red Hat JBoss Data Grid executing node, JBoss Data Grid's CDI mechanism provides an appropriate cache reference, and injects it to the executing Callable . To use the JBoss Data Grid CDI with Callable : Declare a Cache field in Callable and annotate it with org.infinispan.cdi.Input Include the mandatory @Inject annotation. Example 17.2. Using Callable and the CDI Report a bug
public class CallableWithInjectedCache implements Callable<Integer>, Serializable { @Inject @Input private Cache<String, String> cache; @Override public Integer call() throws Exception { //use injected cache reference return 1; } }
