Example 1 with GuiceComponentFactory

use of ru.vyarus.dropwizard.guice.module.jersey.support.GuiceComponentFactory in project dropwizard-guicey by xvik.

the class JerseyBinding method bindSpecificComponent.

/**
 * Binds jersey specific component (component implements jersey interface or extends class).
 * Specific binding is required for types directly supported by jersey (e.g. ExceptionMapper).
 * Such types must be bound to target interface directly, otherwise jersey would not be able to resolve them.
 * <p> If type is {@link HK2Managed}, binds directly.
 * Otherwise, use guice "bridge" factory to lazily bind type.</p>
 *
 * @param binder       hk binder
 * @param injector     guice injector
 * @param type         type which implements specific jersey interface or extends class
 * @param specificType specific jersey type (interface or abstract class)
