| <div class="block">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. |
| <p> |
| The JAX-RS runtime will instantiate the object and inject all it's fields and properties annotated with either one of |
| the <code>@XxxParam</code> annotation (<a href="../../../jakarta/ws/rs/PathParam.html" title="annotation in jakarta.ws.rs"><code>@PathParam</code></a>, <a href="../../../jakarta/ws/rs/FormParam.html" title="annotation in jakarta.ws.rs"><code>@FormParam</code></a> ...) or the |
| <a href="../../../jakarta/ws/rs/core/Context.html" title="annotation in jakarta.ws.rs.core"><code>@Context</code></a> annotation. For the POJO classes same instantiation and injection rules |
| apply as in case of instantiation and injection of request-scoped root resource classes. |
| </p> |
| For example: |
| |
| <PRE> |
| 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) {...} |
| |
| ... |
| } |
| </PRE> |
| <p> |
| 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. |
