@groovy.transform.CompileStatic
trait Interceptor
extends java.lang.Object
implements DataBinder, RequestForwarder, ResponseRedirector, ResponseRenderer, ServletAttributes, WebAttributes, org.springframework.core.Ordered
```
An interceptor can be used to intercept requests to controllers and URIs They replace the notion of filters from earlier versions of Grails, prior to Grails 3.0
