Bean Injection Page edited by Claus Ibsen Changes (2) h3. Bean Injection We support the injection of various resources using @EndpointInject or @BeanInject. This can be used to inject * [Endpoint] instances which can be used for testing when used with [Mock] endpoints; see the [Spring Testing] for an example. * [ProducerTemplate] instances for [POJO Producing] * client side proxies for [POJO Producing] which is a simple approach to [Spring Remoting] h4. Using @BeanInject From *Camel 2.13* onwards you can inject beans (obtained from the [Registry]) into your beans such as {{RouteBuilder}} classes. For example to inject a bean named foo, you can enlist the bean in the [Registry] such as in a Spring XML file: {code:xml} <bean id="foo" class="com.foo.MyFooBean"/> {code} And then in a Java {{RouteBuilder}} class, you can inject the bean using {{@BeanInject}} as shown below: {code} public class MyRouteBuilder extends RouteBuilder { @BeanInject("foo") MyFooBean foo; public void configure() throws Exception { .. } } {code} If you omit the name, then Camel does a lookup by type, and injects the bean if there is exactly only one bean of that type enlisted in the [Registry]. {code} @BeanInject MyFooBean foo; {code} Full Content Bean Injection We support the injection of various resources using @EndpointInject or @BeanInject.
