To obtain the complete response object using @FeignClient(name = "RemoteRegister", url = "${register-config.url}")
, you can follow the same approach mentioned earlier. You need to create a custom ErrorDecoder
and configure it in a configuration class.
Let's go through the steps again:
- Create the custom
ErrorDecoder
:
import feign.Response;
import feign.codec.ErrorDecoder;
public class CustomErrorDecoder implements ErrorDecoder {
@Override
public Exception decode(String methodKey, Response response) {
// Here you can process the complete response object
// response contains the status, headers, and body of the response
return new MyCustomException(response);
}
}
- Create a Feign client interface and set the
errorDecoder
attribute to your custom error decoder:
import feign.*;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.context.annotation.Bean;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@FeignClient(name = "RemoteRegister", url = "${register-config.url}", configuration = MyFeignClientConfiguration.class)
public interface MyServiceClient {
@GetMapping("/api/resource")
@ResponseBody
MyResponseObject getResource();
}
class MyResponseObject {
// Custom response object structure
}
- Create a configuration class where you define the custom
ErrorDecoder
bean:
import feign.codec.ErrorDecoder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class MyFeignClientConfiguration {
@Bean
public ErrorDecoder errorDecoder() {
return new CustomErrorDecoder();
}
}
Make sure the MyFeignClientConfiguration
class is properly annotated with @Configuration
.
- Use the
@FeignClient
withFeignClientBuilder
to create the Feign client:
import org.springframework.cloud.openfeign.FeignClientBuilder;
public class OpenFeignExample {
public static void main(String[] args) {
FeignClientBuilder builder = FeignClientBuilder.builder();
// Create the Feign client
MyServiceClient myService = builder.target(MyServiceClient.class, "${register-config.url}");
// Call the method to get the response
MyResponseObject response = myService.getResource();
// Process the response
}
}
By following these steps and setting the custom ErrorDecoder
in the MyFeignClientConfiguration
class, you can obtain the complete Response
object when making requests with the Feign client created using @FeignClient(name = "RemoteRegister", url = "${register-config.url}")
.
