@FeignClient(name = "RemoteRegister", url = "${register-config.url}") 方式如何获取如何获取完整的响应对象

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:

1. 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);
    }
}

1. 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
}

1. 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.

1. Use the @FeignClient with FeignClientBuilder 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}").
