Jmeter实现dubbo接口压测案例

当前项目中重构了消息服务，需要对消息服务接口做性能压测，评估消息服务的性能情况

通过和开发对接，目前消息服务是通过dubbo接口对内提供服务，所以才有了这边文章的记录

最初的压测这个dubbo接口有三种思路：

1.第一种就是基于业务，比如注册业务，注册成功后，会发送短信消息到用户手机，通过业务调用消息服务，最容易实现，但是业务瓶颈最大导致测试结果不准

2.第二种是通过将dubbo接口上面做一层包装，提供一个http接口访问dubbo接口，需要提供二次开发，需要时间，而且高并发下，需要部署在tomcat容器内部

3.就是直接压测dubbo接口，这种测试的结果最准确，目前有开源的jmeter plguin sampler插件使用

下面讲解怎么使用jmeter-plugins-dubbo做接口测试

第一步：

源码下载：https://github.com/dubbo/jmeter-plugins-dubbo

https://github.com/ningyu1/jmeter-plugins-dubbo/tree/master/dist jar下载地址

注意：

jmeter-plugins-dubbo使用

下载提供2种版本：

A. 第一种版本是jmeter-plugins-dubbo-1.3.8-jar-with-dependencies.jar类似带有with-dependencies的jar是包含一些基础包，建议下载这个

B. 第二种是不带依赖包的版本，例如jmeter-plugins-dubbo-1.3.8-SNAPSHOT.jar。然后获取以下依赖包，将它们放到jmeter安装目录下的lib/ext。如果是项目中使用报错，或者dubbo版本不是2.X版本的，建议下载这个

gson-2.8.2.jar

dubbo-2.8.4.jar

javassist-3.21.0-GA.jar

jline-0.9.94.jar

log4j-over-slf4j-1.7.5.jar

netty-3.7.0.Final.jar

slf4j-api-1.7.5.jar

zkclient-0.2.jar

zookeeper-3.4.9.jar

第二步：

将下载的https://raw.githubusercontent.com/ningyu1/jmeter-plugins-dubbo/master/dist/jmeter-plugins-dubbo-1.3.8.jar

放在jar文件JMETER_HOME/lib/ext目录下

然后启动Jmeter

添加Dubbo Sampler配置如下

直接调用后，报错如下：

是不是看到这里已经懵逼了啊。哈哈，既然出现了问题，那么就要学着分析：首先查看这个接口的实际调用的参数咋样：

通过dubbo默认提供的invoke指令查看：

方法也存在，那么继续查看这个方法的dubbo调用参数

ls -l

url转码后：

通过查看和对比，参数也没错，然后尝试直连，还是报错：
