This project requires Java 11 based on OpenJDK or later.

Overhead

We try to keep overhead to a minimum and the only additional allocations besides the JFR events are URI#toString().

Usage

@Configuration
public class RestConfiguration {

   @Bean
   public RestOperations restOperations() {
     ClientHttpRequestFactory requestFactory = ...;
     RestOperations restOperations = new RestTemplate(requestFactory);
     return new JfrRestOperations(restOperations);
   }

}
