public @interface Uri {

    
Specifies the URI of the injected 
resource target. The value must be in the form of absolute URI if not used from inside of a JAX-RS component class. For example: 
public class AuditingFilter implements RequestFilter {
   @Uri("users/{name}/orders")
   WebTarget userOrders;
   // An external resource target
   @Uri("http://mail.acme.com/accounts/{name}")
   WebTarget userEmailAccount;
   // An external, template-based resource target
   @Uri("http://{audit-host}:{audit-port}/auditlogs/")
   WebTarget auditLogs;
   ...
}

If used from within a JAX-RS component class (e.g. resource, filter, provider … ),
the value can take a form of absolute or relative URI.
A relative URI is resolved using the context path of the application as the base URI.
For example:
public class AuditingFilter implements RequestFilter {
   @Uri("audit/logs")
   WebTarget applicationLogs;
   @Uri("http://sales.acme.com/audit/logs")
   WebTarget domainLogs;
   ...
}
 In case the annotation is used from a JAX-RS resource class, an absolute or relative URI template value may be provided. The template parameter (e.g. {id}) values are automatically resolved in the context of the enclosing resource class path template as well as the context of the processed request. Other defined template parameters have to be resolved before invocation of managed web target. For example: 
@Path("users/{name}")
public class MyResource {
   @Uri("users/{name}/orders")
   WebTarget userOrders;
   @Uri("http://mail.acme.com/accounts/{name}")
   WebTarget userEmailAccount;
   ...
}
