With resttemplate, there is an interceptor that can perform corresponding interception operations. With feignclient, the default implementation is not available, but the implementation of okhttp is adopted.

Interceptor instance

@Component
public class OkHttpLoggingInterceptor implements Interceptor {

    private static final Logger LOGGER = LoggerFactory.getLogger(OkHttpLoggingInterceptor.class);

    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();

        //before , request.body()

        try {
            Response response = chain.proceed(request);
        //after
            return response;
        }catch (Exception e) {
            //log error
            throw e;
        }finally {
            //clean up 
        }
    }
}

Feign configuration

    @Bean
    @ConditionalOnBean(OkHttpLoggingInterceptor.class)
    public okhttp3.OkHttpClient okHttpClient(@Autowired
                                             OkHttpLoggingInterceptor okHttpLoggingInterceptor){
        okhttp3.OkHttpClient.Builder ClientBuilder = new okhttp3.OkHttpClient.Builder()
                .readTimeout(30, TimeUnit.SECONDS) //读取超时
                .connectTimeout(10, TimeUnit.SECONDS) //连接超时
                .writeTimeout(60, TimeUnit.SECONDS) //写入超时
                .connectionPool(new ConnectionPool(10 /*maxIdleConnections*/, 3, TimeUnit.MINUTES))
                .addInterceptor(okHttpLoggingInterceptor);
        return ClientBuilder.build();
    }

In this way, we are almost done.
