<artifactId>jfr-resttemplate</artifactId>
<version>0.2.1</version>
</dependency>
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);
}
}
