## Annotation Type BeanParam

-     @Target(value={PARAMETER,METHOD,FIELD})
      @Retention(value=RUNTIME)
      @Documented
      public @interface BeanParam

  The annotation that may be used to inject custom JAX-RS "parameter aggregator" value object into a resource class field, property or resource method parameter.

  The JAX-RS runtime will instantiate the object and inject all it's fields and properties annotated with either one of the `@XxxParam` annotation (`@PathParam`, `@FormParam` ...) or the `@Context` annotation. For the POJO classes same instantiation and injection rules apply as in case of instantiation and injection of request-scoped root resource classes.

  For example:

       public class MyBean {
         @FormParam("myData")
         private String data;

         @HeaderParam("myHeader")
         private String header;

         @PathParam("id")
         public void setResourceId(String id) {...}

         ...
       }

       @Path("myresources")
       public class MyResources {
         @POST
         @Path("{id}")
         public void post(@BeanParam MyBean myBean) {...}

         ...
       }

  Because injection occurs at object creation time, use of this annotation on resource class fields and bean properties is only supported for the default per-request resource class lifecycle. Resource classes using other lifecycles should only use this annotation on resource method parameters.
