关于dubbo的RPC和RESTful性能及对比
作者：fomeiherz
这篇文章主要介绍了关于dubbo的RPC和RESTful性能及对比，具有很好的参考价值，希望对大家有所帮助。如有错误或未考虑完全的地方，望不吝赐教
先上结论
RPC请求的效率是HTTP请求的1.6倍左右，性能明显比HTTP请求要高很多。
原因分析
RESTful是基于HTTP协议进行交互的，HTTP协议包含大量的请求头、响应头信息。
而dubbo是基于dubbo自定义的二进制协议进行传输，消息体比较简单，传输数据要小很多。
HTTP请求代码
// 服务端基于spring boot搭建
// 服务端代码
@SpringBootApplication
@RestController
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
@RequestMapping("/helloworld")
public String helloworld() {
return "hello world";
}
}
// 客户端代码
import org.springframework.util.StopWatch;
import org.springframework.web.client.RestTemplate;
public class HelloworldTest {
public static void main(String[] args) {
RestTemplate restTemplate = new RestTemplate();
StopWatch stopWatch = new StopWatch();
stopWatch.start();
for (int j = 0; j < 10; j++) {
System.out.println("------------------");
for (int i = 1; i <= 10000; i++) {
restTemplate.getForObject("http://127.0.0.1/helloworld", String.class);
if (i % 1000 == 0) {
stopWatch.stop();
System.out.println(stopWatch.getTotalTimeSeconds());
stopWatch = new StopWatch();
stopWatch.start();
}
}
}
}
}
RPC代码
// dubbo-demo工程的代码，详情请看：https://github.com/apache/dubbo/tree/master/dubbo-demo
// 服务端
public class DemoServiceImpl implements DemoService {
@Override
public String sayHello(String name) {
return "Hello " + name + ", response from provider: " + RpcContext.getContext().getLocalAddress();
}
}
// 客户端
public class Consumer {
public static void main(String[] args) {
//Prevent to get IPV6 address,this way only work in debug mode
//But you can pass use -Djava.net.preferIPv4Stack=true,then it work well whether in debug mode or not
System.setProperty("java.net.preferIPv4Stack", "true");
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"META-INF/spring/dubbo-demo-consumer.xml"});
context.start();
DemoService demoService = (DemoService) context.getBean("demoService"); // get remote service proxy
StopWatch stopWatch = new StopWatch();
stopWatch.start();
for (int j = 0; j < 10; j++) {
System.out.println("-----------");
for (int i = 1; i <= 10000; i++) {
demoService.sayHello("world"); // call remote method
if (i % 1000 == 0) {
stopWatch.stop();
System.out.println(stopWatch.getTotalTimeSeconds());
stopWatch = new StopWatch();
stopWatch.start();
}
}
}
}
}
