mod-lang-spring

Language support implementation for Spring Framework applications on vert.x 2.0.

HowTo use mod-lang-spring

Module Configuration

1. Clone the repo and build the distribution package (./gradlew dist). You'll find it in: build/distributions. Unzip it in $VERTX_HOME/lib.

2. Using the prefix 'spring:', specify a Spring configuration file in your verticle or module's mod.json:

   { "main": "spring:mySpringConfig.xml", "worker": true }

3. Alternatively, if you provide cglib in your application, you can specify an annotated @Configuration class in your verticle or module's mod.json:

   { "main": "spring:my.example.ConfigClass", "worker": true }

Application Components

In a bean annotated with @Component, created in an @Configuration class, or declared in an Spring Framework XML configuration file, you can annotate a method with the @EventBusHandler annotation. The application context will automatically register a vert.x event bus Handler that delegates to this method, on the address specified in the annotation.

If the method returns a value, then it is sent as a reply to the sender of the event.

@Component
public class ExampleReplyingEventBusHandler {

  @EventBusHandler("some.address.to.listen")
  public Object anyMethod(Object payload) {
    return payload;
  }
}
