Represents a functionality of the container to inject resources to application service endpoint object (usually but not necessarily as per JavaEE spec.)
If {@link Container#getSPI(Class)} returns a valid instance of {@link ResourceInjector}, The JAX-WS RI will call the {@link #inject} method for each service endpointinstance that it manages.
The JAX-WS RI will be responsible for calling {@link PostConstruct} callback,so implementations of this class need not do so.
