org.axonframework.eventhandling.ClassNamePatternClusterSelector

ClusterSelector implementation that chooses a Cluster based on whether the Listener's Class Name matches a given Pattern.

The given pattern must match the entire class name, not just part of it.

Note that the name of the class used is the name of the class implementing the EventListener interface. If a listener implements the EventListenerProxy interface, the value of the {@link org.axonframework.eventhandling.EventListenerProxy#getTargetType()} is used. Annotated Event Listeners will alwayshave the actual annotated class name used. @author Allard Buijze @since 2.0


        // to make sure Listeners are assigned to their respective cluster, we create a number of selectors that we
        // combine into a single ClusterSelector using a CompositeClusterSelector
        ClusterSelector clusterSelector = new CompositeClusterSelector(Arrays.<ClusterSelector>asList(
                // this one will accept
                new ClassNamePatternClusterSelector(Pattern.compile(".*Another.*"), asyncCluster),
                new DefaultClusterSelector(standardCluster)
        ));


        // create the event bus and subscribe two listeners
        // notice how the registration process itself is unaware of clustering


    @Test
    public void testMatchesPattern() throws Exception {
        Cluster cluster = mock(Cluster.class);
        Pattern pattern = Pattern.compile("org\\.axonframework.*\\$1");
        ClassNamePatternClusterSelector testSubject = new ClassNamePatternClusterSelector(pattern, cluster);


        Cluster actual = testSubject.selectCluster(new EventListener() {
            @Override
            public void handle(EventMessage event) {
            }
        });
        assertSame(cluster, actual);
