使用dubbo 2.7 编写接口，使用jmeter调用

创建spring-boot

winddows 安装 zookeeper3.4.14 并启动

父项目用的boot创建的时候添加web依赖，其他用的是maven

父项目pom

common 接口，实体类

接口实现类

接口实现类

启动类

配置文件

server:
  port: 9001
dubbo:
  application:
    # 服务名称，保持唯一
    name: server-provider
    # zookeeper地址，用于向其注册服务
  registry:
    protocal: zookeeper
    address: zookeeper://127.0.0.1:2181
  protocol:
    name: dubbo
    port: 20882
  metadata-report:
    address: zookeeper://127.0.0.1:2181
  config-center:
    address: zookeeper://127.0.0.1:2181

运行启动类，看到这个就成了

使用父项目打包，把server-provider的jar包放到jmeter 的 lib/ext目录下
把jmeter的dubbo插件也放到 扩展目录下

启动jmeter

添加 dubbo取样器

• 添加注册中心的类型、地址
• 点击那个Get按钮从注册中心获取服务列表，填写接口入参
  

总结：主要是依赖难搞，百度了一大圈，dubbo 2.7 版本变化也大 。

jmeter调用的原理，相当于编写一个消费者，也可以用代码编写消费者，使用@RestController对外提供接口，jmeter就可以通过http调用消费者，达到调用dubbo接口的效果
