Events for RestEasy

Sometime we need to do a little bit more when a REST API is called, but in doing so we slow down the REST API itself.
Events for RestEasy is a simple library that enables triggering of custom events when a REST API is called.

Event triggering supports:

• asynchronous event execution
• events on specific response codes
• exception based event triggers
• exception handling and wrapping to JSON response
• Guice for dependency injection

Setup

 <dependency>      
      <groupId>com.zandero</groupId>      
      <artifactId>rest.events</artifactId>      
      <version>1.2</version>      
 </dependency>

Example

Simple event triggered on every call to /ping

@GET
@Path("/ping")
@RestEvent(processor = PingEvent.class)
@Produces(MediaType.APPLICATION_JSON)
public String ping() {

    return "ping";
}

public class PingEvent implements RestEventProcessor {
    @Override
    public RestEventResult execute(Serializable entity, RestEventContext context) throws Exception {
        // magic happens here
        return RestEventResult.ok();
    }
}
