一.先了解下 dubbo 的原理，最好自己搭建一个案例
可参考以下方式搭建
http://09792bb8.wiz03.com/share/s/09uiKU3j2kR120MIpT2AdLm70pfBmE1zFApv2jiDZ01GhE8j

二.编写 dubbo 测试脚本
源码：
https://git.coding.net/mgjerome/jmeter_dubbo.git
1.创建 jmeter_dubbo Maven 项目

直接 Next 创建项目

2.添加 pom.xml 配置

<properties>
    <spring.version>3.2.4.RELEASE</spring.version>
</properties>
<dependencies>
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>dubbo</artifactId>
        <version>2.5.3</version>
        <exclusions>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <!--dubbo注册中心-->
    <dependency>
        <groupId>org.apache.zookeeper</groupId>
        <artifactId>zookeeper</artifactId>
        <version>3.4.6</version>
    </dependency>
    <!--zookeeper客户端-->
    <dependency>
        <groupId>com.github.sgroschupf</groupId>
        <artifactId>zkclient</artifactId>
        <version>0.1</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>${spring.version}</version>
    </dependency>
</dependencies>

3.resources 目录下创建 lib 文件夹存放, dubbo 接口 jar
ApacheJMeter_core.jar ApacheJMeter_java.jar (apache-jmeter-3.2\lib\ext 目录下)
jorphan.jar(apache-jmeter-3.2\lib 目录下用于 main 调试执行)
dubbo.xsd(由于http://code.alibabatech.com/schema/dubbo/dubbo.xsd 服务已停用从网上下载该文件，或者从 dubbo-2.5.3.jar META-INF 目录下导出
)

4.创建 dubbo 消费者 xml 文件 consumer.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://code.alibabatech.com/schema/dubbo
      ./dubbo.xsd"
>
    <!-- 消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 -->
    <dubbo:application name="hello-consumer" />
    <!-- 使用multicast广播注册中心暴露发现服务地址 -->
    <dubbo:registry address="zookeeper://127.0.0.1:2181" />
    <!-- 生成远程服务代理，可以和本地bean一样使用demoService -->
    <dubbo:reference id="helloService" interface="com.service.HelloService" />

</beans>

5.编写 jmeter 脚本

package com.buddo;

import com.service.HelloService;
import org.apache.jmeter.config.Arguments;
import org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient;
import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext;
import org.apache.jmeter.samplers.SampleResult;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * Created by CWGJ008 on 2017/10/13.
 */
public class Dubbo_port extends AbstractJavaSamplerClient {

    private static  ApplicationContext context = new ClassPathXmlApplicationContext("consumer.xml");
    private static HelloService helloService;
    private static long start = 0;
    private static long end = 0;

    public void setupTest(JavaSamplerContext arg0){
        helloService=(HelloService)context.getBean("helloService");
        start = System.currentTimeMillis();
    }

    public SampleResult runTest(JavaSamplerContext javaSamplerContext) {
        SampleResult sr = new SampleResult();
        sr.setSamplerData("dubbo测试案例");
        sr.sampleStart();// jmeter 开始统计响应时间标记
        String result = helloService.speakHello("chen");
        System.out.println(result);
        if(result.contains("chen")){
            sr.setResponseData("结果是：" + result, null);
            sr.setDataType(SampleResult.TEXT);
            sr.setSuccessful(true);
        }else {
            sr.setSuccessful(false);
        }
        sr.sampleEnd();// jmeter 结束统计响应时间标记
        return sr;
    }

    //测试结束时调用；
    public void teardownTest(JavaSamplerContext arg0) {
        end = System.currentTimeMillis();
        // 总体耗时
        System.err.println("cost time:" + (end - start) + "毫秒");
    }
}

6.编写测试类，测试执行完打包时记得注解

package com.buddo;

import org.apache.jmeter.config.Arguments;
import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext;

/**
 * Created by CWGJ008 on 2017/10/13.
 */
public class TestMain {
    public static final void  main(String [] args){

        JavaSamplerContext arg0 = new JavaSamplerContext(new Arguments());

        Dubbo_port test=new Dubbo_port();
        test.setupTest(arg0);
        test.runTest(arg0);

    }
}
