JarCastingEvents 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();
}
}
