本文介绍了使用JMeter进行Dubbo接口压力测试的经历，包括遇到的挑战，如Disruptor框架的高性能特性、服务器高并发写入数据库的场景，以及在打包JMeter测试脚本时遭遇的依赖问题。重点在于解决JMeter启动失败的问题，提示需要手动筛选必要的jar文件放入lib/ext目录，以确保JMeter能正常运行。

最近看了Disruptor框架，

官方号称它能够在一个线程里每秒处理6百万订单.

一个仅仅部署在4台服务器上的服务，每秒向Database写入数据超过100万行数据，每分钟产生超过1G的数据

自己就想搞个压测测一下，但是过程有点曲折

直接上代码

public class Caller extends AbstractJavaSamplerClient {

    private static DubboInit dubboInit;
    private static OperateRecordServiceFacade facade;

    @Override
    public void setupTest(JavaSamplerContext context) {
        getLogger().info("start....");
        dubboInit = DubboInit.getInstance();
        dubboInit.initApplicationContext();
        facade = (OperateRecordServiceFacade) dubboInit.getBean("operateRecordServiceFacade");
    }

    @Override
    public SampleResult runTest(JavaSamplerContext javaSamplerContext) {
        getLogger().info("start...");
        OperateRecordDTO dto = new OperateRecordDTO();
        dto.setOperateType(OperateTypeEnum.MODIFY_CREDIT_RESULT.getCode());
        dto.setOperateDesc("test");
        dto.setOperator("tests");
        facade.saveAndUpdate(dto);
        SampleResult sr = new SampleResult();
        sr.sampleStart();
        sr.setSuccessful(true);
        sr.sampleEnd();
        getLogger().info("end...");
        return sr;
    }

    public static void main(String[] args) {
        dubboInit = DubboInit.getInstance();
        dubboInit.initApplicationContext();
        facade = (OperateRecordServiceFacade) dubboInit.getBean("operateRecordServiceFacade");
        OperateRecordDTO dto = new OperateRecordDTO();
        dto.setOperateType(OperateTypeEnum.MODIFY_CREDIT_RESULT.getCode());
        dto.setOperateDesc("test");
        dto.setOperator("tests");
        facade.saveAndUpdate(dto);
    }
}

public class DubboInit {

    private static DubboInit init = null;
    private DubboInit(){}
    private static ApplicationContext context;
    public synchronized static DubboInit getInstance(){
        if(init == null){
            init = new DubboInit();
        }
        return init;
    }

    public static void initApplicationContext(){
        context = new ClassPathXmlApplicationContext("classpath:/dubbo.xml");
        if(context==null)
        {
            throw new IllegalArgumentException("Load dubbo-client.xml fail");
        }
    }

    public Object getBean(String beanName) {
        return context.getBean(beanName);
    }

}

主要的坑就是打包的时候依赖包的问题

打包的时候把所有的dependencies都打到lib文件夹里面，但是不能直接把jar都复制到Jmeter的lib/ext里面，不然会导致启动不了

建议手动筛选必要的jar到ext下，这个折腾了好久，手动筛选之后就可以启动了。

ps：该实例是1.7java 普通maven项目，不是spring boot项目
