如何通过feign获取第三方的返回body

import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.http.ResponseEntity;


@FeignClient(name = "xxx", url = "xxx", configuration = {ErrorNewDecoder.class})
public interface SingleVehicleConfigUpdaterClient {


    @PostMapping(SINGLE_VEHICLE_REMOTE_CONFIG)
    ResponseEntity configCtl(@RequestBody xxx  request);
}

上面是调用第三方，然后configuration里面配置需要自己重新定义

import com.alibaba.fastjson.JSON;
import com.beantechs.tsp.backend.common.error.BackendError;
import com.beantechs.tsp.backend.common.exception.BackendException;
import feign.Response;
import feign.Util;
import feign.codec.ErrorDecoder;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;

import java.io.IOException;
import java.util.Map;

/**
 * 
 */
@Slf4j
public class ErrorNewDecoder implements ErrorDecoder {

    @Autowired
    private ConfigurationClass configurationClass;

    private ErrorDecoder defErrorDecoder = new Default();



    @Override
    public Exception decode(String methodKey, Response response) {
        try {
            if (response.status() != 200 && response.status() != 201 && response.status() != 204) {
                if (null != response.body()) {
                    String message = Util.toString(response.body().asReader());
                    log.error("请求异常:{}", message);
                 
                }
            }
        } catch (IOException ex) {
            log.error(ex.getMessage(), ex);
        }
        return defErrorDecoder.decode(methodKey, response);
    }
}
