Annotation Type HeaderParam

public @interface HeaderParam

Qualifies injection points that should have their values fetched from a corresponding HTTP header.

Example usage:

 private String cacheControl;

Example usage with default value

 private String cacheControl;

Because the bean produced is dependent-scoped, use of this annotation on class fields and bean properties is only safe for request-scoped beans. Beans with longer scopes should wrap this bean in a provider and retrieve the value on demand.

 @Inject @HeaderParam("Cache-Control")
 private Instance<String> cacheControlProvider;


 String cacheControl = cacheControlProvider.get();
