JAX-RS Sub-resources

JAX-RS Sub-resources
Root resources can declare sub-resources that will
match the unmatched part of the URI path

• Sub-resources method
  A sub-resource method is decorated with both a @Path
  annotation and one of the HTTP verb annotations. The subresource
  method is directly responsible for handling a request
  made on the resource using the specified HTTP verb.
  


• Sub-resource locator
  Sub-resource locators are not decorated with one of the
  HTTP verb annotations and do not directly handle are request
  on the sub-resource. Instead, a sub-resource locator returns
  an instance of a resource class that can handle the request.
• Sample
  @Path("properties")
  public class Props {
  @GET
  @Path("java.home")
  Prop getProperty() {…}
  @Path("{name}")
  Object getProp(@PathParam("name")String
  name){
  return new Dyna(name); }
  }
  public class Dyna {
  @GET Prop getProperty() {…}
  }
  GET http://.../context/properties/java.home
  GET http://.../context/properties/java.tmp.dir
