Camel 2.10: If used on the consumer side of the route, will filter events received from the |
Usage
Using guava-eventbus
component on the consumer side of the route will capture messages sent to the Guava EventBus
and forward them to the Camel route. Guava EventBus consumer processes incoming messages asynchronously.
SimpleRegistry registry = new SimpleRegistry(); EventBus eventBus = new EventBus(); registry.put("busName", eventBus); CamelContext camel = new DefaultCamelContext(registry); from("guava-eventbus:busName").to("seda:queue"); eventBus.post("Send me to the SEDA queue.");
Using guava-eventbus
component on the producer side of the route will forward body of the Camel exchanges to the Guava EventBus
instance.
SimpleRegistry registry = new SimpleRegistry(); EventBus eventBus = new EventBus(); registry.put("busName", eventBus); CamelContext camel = new DefaultCamelContext(registry); from("direct:start").to("guava-eventbus:busName"); ProducerTemplate producerTemplate = camel.createProducerTemplate(); producer.sendBody("direct:start", "Send me to the Guava EventBus."); eventBus.register(new Object(){ @Subscribe public void messageHander(String message) { System.out.println("Message received from the Camel: " + message); } });
