JAX-RS writer interceptor works for every response even with NameBinding - jax-rs

Question

I need to intercept a response from the server that was generated for a specific API call and change it.
I used the JAX-RS 'WriterInterceptor' for this and I have created a NameBinding as well. But the server is intercepting every response out from the server. What am I doing wrong here?
Shown below is the code I have tried. Why is the name binding does not work? (I have verified that when calling other API resources the particular method that I have use name binding is not called.)
Name Binding.
package com.example.common.cm.endpoint;
#Target({ElementType.TYPE, ElementType.METHOD})
#NameBinding
#Retention(RetentionPolicy.RUNTIME)
public #interface JSONtoJWT {}
The Interceptor.
package com.example.common.cm.endpoint;
#Provider
#JSONtoJWT
public class TestInterceptor implements WriterInterceptor {
private static final Log log = LogFactory.getLog(TestInterceptor.class);
#Override
public void aroundWriteTo(WriterInterceptorContext writerInterceptorContext) throws IOException, WebApplicationException {
log.info("interceptor invoked");
OutputStream outputStream = writerInterceptorContext.getOutputStream();
outputStream.write(("{\"message\": \"Message added in the writer interceptor in the server side\"}").getBytes());
writerInterceptorContext.setOutputStream(outputStream);
writerInterceptorContext.proceed();
log.info("Proceeded");
}
}
API Resource.
package com.example.cm.endpoint.u3.acc;
#Path("/u3/some-validation")
#Consumes({ "application/json; charset=utf-8" })
#Produces({ "application/json; charset=utf-8" })
public class SomeValidationApi {
#POST
#Path("/")
#JSONtoJWT
#Consumes({ "application/json; charset=utf-8" })
#Produces({ "application/json; charset=utf-8" })
public Response someValidationPost(#ApiParam(value = "validations post" ,required=true ) SomeValidationRequestDTO someValidationConsent)
{
return delegate.someValidationPost(someValidationConsent);
}
}

<bean class="com.example.common.cm.endpoint.TestInterceptor"/>

</jaxrs:server>
</beans>
When I use the above every response from the server is intercepted and the message is added. But I want only the particular resource to invoke the Interceptor.
Also, Other than JAX-RS interceptor with writerInterceptor, are there any other good alternative to achieve this?
