Feign的接口日志

一 实例

package org.crazyit.cloud.log;

import org.crazyit.cloud.HelloClient;
import org.crazyit.cloud.interceptor.MyInterceptor;

import feign.Feign;
import feign.Logger;

public class LogMain {

    public static void main(String[] args) {
        /**
         * NONE：默认值，不记录日志
         * BASIC：记录请求方法、URL、响应状态代码和执行时间
         * HEADERS：除BASIC记录的日志外，还会记录请求头和响应头的信息
         * FULLL：在HEADERS的基础上，请求和响应的元数据，都会保存
         */
        HelloClient client = Feign.builder()
                .logLevel(Logger.Level.FULL)
                .logger(new Logger.JavaLogger().appendToFile("logs/http.log"))
                .target(HelloClient.class,
                "http://localhost:8080");
        String result = client.hello();
        System.out.println(result);
    }

}

二 启动服务类

三 测试结果

[HelloClient#hello] ---> GET http://localhost:8080/hello HTTP/1.1

[HelloClient#hello] ---> END HTTP (0-byte body)

[HelloClient#hello] <--- HTTP/1.1 200 (73ms)

[HelloClient#hello] content-length: 11

[HelloClient#hello] content-type: text/plain;charset=UTF-8

[HelloClient#hello] date: Sat, 21 Jul 2018 03:42:20 GMT

[HelloClient#hello]

[HelloClient#hello] Hello World

[HelloClient#hello] <--- END HTTP (11-byte body)
