Class Application

java.lang.Object
javax.ws.rs.core.Application

public class Application extends Object
Defines the components of a JAX-RS application and supplies additional metadata. A JAX-RS application or implementation supplies a concrete subclass of this abstract class.

The implementation-created instance of an Application subclass may be injected into resource classes and providers using Context.

    • getClasses

      public Set<Class<?>> getClasses()
      Get a set of root resource and provider classes. The default lifecycle for resource class instances is per-request. The default lifecycle for providers is singleton.

      Implementations should warn about and ignore classes that do not conform to the requirements of root resource or provider classes. Implementations should warn about and ignore classes for which getSingletons() returns an instance. Implementations MUST NOT modify the returned set.

      The default implementation returns an empty set.

      Returns:
      a set of root resource and provider classes. Returning null is equivalent to returning an empty set.
    • getSingletons

      public Set<Object> getSingletons()
      Get a set of root resource and provider instances. Fields and properties of returned instances are injected with their declared dependencies (see Context) by the runtime prior to use.

      Implementations should warn about and ignore classes that do not conform to the requirements of root resource or provider classes. Implementations should flag an error if the returned set includes more than one instance of the same class. Implementations MUST NOT modify the returned set.

      The default implementation returns an empty set.

      Returns:
      a set of root resource and provider instances. Returning null is equivalent to returning an empty set.
