Package io.micronaut.web.router.filter

Class FilteredRouter

java.lang.Object

io.micronaut.web.router.filter.FilteredRouter

All Implemented Interfaces:

Router

public class FilteredRouter
extends Object
implements Router

Allows decorating an existing Router with filtering capabilities.

Filters themselves should be supplied via the RouteMatchFilter interface.

A filtered router can be enabled by implementing a BeanCreatedEventListener for the existing Router and decorating appropriately. See for example VersionAwareRouterListener

Since:

1.1.0
