jmeter测试rpc接口-使用dubbo框架调用【杭州多测师_王sir】

git clone -b master https://github.com/apache/dubbo-samples.git
cd dubbo-samples/dubbo-samples-spring-boot
mvn clean package // 打包成jar
//启动生产者服务
cd ./dubbo-samples-spring-boot-provider
java -jar ./target/dubbo-samples-spring-boot-provider-1.0-SNAPSHOT.jar
// 启动消费者服务
java -jar ./target/dubbo-samples-spring-boot-consumer-1.0-SNAPSHOT.jar

1. 定义服务接口
dubbo-samples-spring-boot-interface/DemoService.java

package org.apache.dubbo.samples.basic.api;

public interface DemoService {
    String sayHello(String name);
}
2. 提供方实现接口并暴露服务
dubbo-samples-spring-boot-provider/DemoServiceImpl.java
@DubboService
public class DemoServiceImpl implements DemoService {
    @Override
    public String sayHello(String name) {
        System.out.println("Hello " + name + ", request from consumer: " + RpcContext.getContext().getRemoteAddress());
        return "Hello " + name;
    }
}
3. 配置 application.yml 文件
dubbo-samples-spring-boot-provider/resources/application.yml
dubbo:
  application:
    name: dubbo-springboot-demo-provider
  protocol:
    name: dubbo
    port: -1
  registry:
    id: zk-registry
    address: zookeeper://127.0.0.1:2181
  config-center:
    address: zookeeper://127.0.0.1:2181
  metadata-report:
    address: zookeeper://127.0.0.1:2181
4. 定义 Spring Boot 主函数，其中，@EnableDubbo 必须配置。

dubbo-samples-spring-boot-provider/ProviderApplication.java
@SpringBootApplication
@EnableDubbo
public class ProviderApplication {
    public static void main(String[] args) throws Exception {
        new EmbeddedZooKeeper(2181, false).start();

        SpringApplication.run(ProviderApplication.class, args);
        System.out.println("dubbo service started");
        new CountDownLatch(1).await();
    }
}

5. 引用远程服务
dubbo-samples-spring-boot-consumer/ConsumerApplication.java

public class ConsumerApplication {
    @DubboReference
    private DemoService demoService;
}
6. 定义 application.yml
dubbo-samples-spring-boot-consumer/application.yml

dubbo:
  application:
    name: dubbo-springboot-demo-consumer
  protocol:
    name: dubbo
    port: -1
  registry:
    id: zk-registry
    address: zookeeper://127.0.0.1:2181
  config-center:
    address: zookeeper://127.0.0.1:2181
  metadata-report:
    address: zookeeper://127.0.0.1:2181
    
 7. 加载 Spring 配置，并调用远程服务
dubbo-samples-spring-boot-consumer/ConsumerApplication.java

@SpringBootApplication
@Service
@EnableDubbo
public class ConsumerApplication {
    @DubboReference
    private DemoService demoService;

    public static void main(String[] args) {
        ConfigurableApplicationContext context = SpringApplication.run(ConsumerApplication.class, args);
        ConsumerApplication application = context.getBean(ConsumerApplication.class);
        String result = application.doSayHello("world");
        System.out.println("result: " + result);
    }
}

注意：
1.启动生产者（provider）项目时会自动关联启动zookeeper，端口占用：2181
2.dubbo服务默认占用端口：20880 
3.jmeter测试时可以使用jar启动项目，也可以使用spring boot启动项目（只启动provider端即可）
