Annotation Type BeanParam

@Target({PARAMETER,METHOD,FIELD}) @Retention(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 {
   private String data;

   private String header;

   public void setResourceId(String id) {...}


 public class MyResources {
   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.
