HttpClient客户端网络编程——高可用、高并发
本文是HttpClient的学习博客，RestTemplate是基于HttpClient的封装，feign可基于HttpClient进行网络通信。
那么作为较底层的客户端网络编程框架，该怎么配置使其能高可用，高并发，可支持Https协议呢？通读本文也许你会有答案或者启发。
本文是Maven项目，基于Spring，在本Demo中使用了更方便的SpringBoot。
以后随着理解HttpClient更深入的时候会不定期更新本博客，也欢迎感兴趣的博友交流和讨论。

4. HttpClient客户端配置类
通过配置连接池管理对象PoolingHttpClientConnectionManager，设置两个重要参数maxTotal和defaultMaxPerRoute，和其它参数。本文参数配置参考官方文档httpcomponents-client-4.5.x，文档上面的参数更多更齐全，包括HttpConnectionFactory、DnsResolver、ConnectionConfig、RequestConfig、RequestConfig、HttpClientContext、设置代理。这些参数本文没有配置，使用HttpClient的默认配置，感兴趣想继续深入研究的可以去学习了解。BackoffManager可以在连接池处于闲暇时进行收缩，不过网络上资料较少，目前还没研究出怎么使用和配置。

6. HttpClient业务接口及其实现
1 package com.example.httpclientdemo.biz.service; 2 3 /** 4 * HttpClient业务接口类 5 * 6 * @author 复姓江山 7 * @date 2021/02/08 8 */ 9 public interface HttpClientService { 10 /** 11 * get请求 12 * 13 * @param url 请求地址 14 */ 15 void requestGet(String url); 16 17 /** 18 * post请求 19 * 20 * @param url 请求地址 21 * @param obj 请求对象 22 */ 23 void requestPost(String url, Object obj); 24 }
1 package com.example.httpclientdemo.biz.service.impl; 2 3 import com.example.httpclientdemo.biz.provider.HttpClientProvider; 4 import com.example.httpclientdemo.biz.service.HttpClientService; 5 import org.springframework.beans.factory.annotation.Autowired; 6 import org.springframework.stereotype.Service; 7 8 /** 9 * HttpClient业务接口实现类 10 * 11 * @author 复姓江山 12 * @date 2021/02/08 13 */ 14 @Service 15 public class HttpClientServiceImpl implements HttpClientService { 16 17 @Autowired 18 private HttpClientProvider httpClientProvider; 19 20 21 @Override 22 public void requestGet(String url) { 23 httpClientProvider.requestGet(url); 24 } 25 26 @Override 27 public void requestPost(String url, Object obj) { 28 httpClientProvider.requestPost(url, obj); 29 } 30 }
7. HttpClient业务支撑接口及其实现
为什么会加个业务支撑接口呢？常见的分层结构或分层架构（控制层、业务层和数据访问层——分层结构，或表示层（UI）、业务逻辑层（BLL）和数据访问层——分层架构），在此基础上增加provder是因为多层封装与隔离，HttpClient是作为客户端请求其它系统服务，请求参数与相应参数及异常处理应与本项目进行一定隔离，如果把HttpClient客户端深度耦合到业务层中，到对方服务器变动时，就会影响本系统的核心业务逻辑。而增加了封装与隔离后，影响的只是provider层，系统本身的核心业务逻辑不会受到深层次的影响。在这我就稍微发散一下思维，比如定义一个MQ的接口，在使用的是Kafka，RabitMQ，ActiveMQ或者RocketMQ，不管怎么变更MQ，系统业务代码依赖的是MQ的接口，丝毫不会受到影响。所以编程原则里有一条：面向接口编程，面向抽象编程。
1 package com.example.httpclientdemo.biz.provider; 2 3 /** 4 * HttpClient业务支撑接口类 5 * 6 * @author 复姓江山 7 * @date 2021/02/08 8 */ 9 public interface HttpClientProvider { 10 11 /** 12 * get请求 13 * 14 * @param url 请求地址 15 */ 16 void requestGet(String url); 17 18 /** 19 * post请求 20 * 21 * @param url 请求地址 22 * @param obj 请求参数 23 */ 24 void requestPost(String url, Object obj); 25 }

8. HttpClient业务接口测试
通过运行单元测试类来测试接口，下文有详细的测试数据。
1 package com.example.httpclientdemo.biz.service; 2 3 import org.junit.jupiter.api.Test; 4 import org.slf4j.Logger; 5 import org.slf4j.LoggerFactory; 6 import org.springframework.beans.factory.annotation.Autowired; 7 import org.springframework.boot.test.context.SpringBootTest; 8 9 import java.util.concurrent.ExecutorService; 10 import java.util.concurrent.Executors; 11 import java.util.concurrent.atomic.AtomicInteger; 12 13 import static org.junit.jupiter.api.Assertions.*; 14 15 @SpringBootTest 16 class HttpClientServiceTest { 17 private final static Logger logger = LoggerFactory.getLogger(HttpClientServiceTest.class); 18 19 @Autowired 20 private HttpClientService httpClientService; 21 22 private static final String URL_GET_PATH = "https://www.baidu.com"; 23 24 private final AtomicInteger count = new AtomicInteger(); 25 26 /** 27 * workStealingPool 28 */ 29 public final static ExecutorService workStealingPool = Executors.newWorkStealingPool(1<<6); 30 31 @Test 32 void requestGet() throws InterruptedException { 33 final long startMils = System.currentTimeMillis(); 34 final long statNanos = System.nanoTime(); 35 for (int i = 0; i < 1000; i++) { 36 workStealingPool.execute(() -> { 37 httpClientService.requestGet(URL_GET_PATH); 38 logger.warn("requestGet, times: {}, betMils: {},betNanos: {}", count.getAndIncrement(), 39 (System.currentTimeMillis() - startMils), (System.nanoTime() - statNanos)); 40 }); 41 42 } 43 Thread.sleep(20000); 44 } 45 46 @Test 47 void requestPost() { 48 } 49 }
三、测试验证
本文测试方式可能不是那么专业与严谨，可是并不妨碍我们通过测试数据看出些原理，总结出些规律，也许有些片面，但可看出些趋势。

在分析数据以前我先罗列一下电脑配置：
Windows 10 专业版
Intel(R) Core(TM) i5-7400 CPU @ 3.00GHz 3.00 GHz 4核
16.0 GB
64 位
SSD 232.89 GB
首先根据本机硬件及系统配置，多线程可以提高系统的并发效率，但是也不是绝对的，大致在50个线程的时候效果较好。然后defaultMaxPerRoute参数也是50，即每个路由默认并行接受的请求数。因为本文的测试目标服务器是百度，百度服务器设置连接时间可无限期的保持“Connection can be kept alive indefinitely”，调节validateAfterInactivity参数，总的来说效果不是很大，当然需要排除网络请求的一些影响因素，比如拥塞、路由等情况，可根据下表的参数比较知道，即使相同的配置参数，不同时间点请求服务器，响应的时长也有差异，也就是说每一次的网络请求都是必然中的一次偶然情况。
3. 同参数比较
Threads: 50
maxTotal: 200
defaultMaxPerRoute:50
validateAfterInactivity:1000
idleTimeOut:3

通过上表可以看出，每一次网络请求在同一网络情况下或相似网络情况下，响应的时长差距不大。但因为影响网络的因素众多，导致每次响应的时长都不一样。
四、后记
暂时先分享到此，后期会有补充的，比如源码、架构等。
