Dubbo
目前是apache托管的开源项目，能够实现RPC
- 注册中心：zookeeper 默认端口2181
- 服务提供者：应用程序
- 服务消费者：使用服务方
- 服务监控：监控
测试服务器环境
测试服务器IP：192.168.9.3 zookeeper端口20181 服务提供者：
- membet1:20882
- membet2:20883
测试dubbo的方法
1.使用Telnet的方式
在mac上运行telnet需要环境
使用Homebrew安装一下
$ brew install telnet
$ telnet 192.168.9.3 20882
使用ls可以查看提供的服务的名称也就是「接口」
使用ls -l可以查看接口的所有方法
dubbo>ls
com.lemon.member.service.MemberService
dubbo>ls -l com.lemon.member.service.MemberService
com.lemon.member.pojo.Member getMember(com.lemon.member.pojo.Member)
void recharge(com.lemon.member.pojo.Recharger)
void withdraw(com.lemon.member.pojo.WithDrawer)
void add(com.lemon.member.pojo.Member)
void update(com.lemon.member.pojo.Member)
java.util.List list()
方法括号中有内容，就是带有参数的方法
Telnet
使用cd进入到服务的名称位置后
dubbo>ls -l
com.lemon.member.service.MemberService -> dubbo://192.168.9.3:20882/com.lemon.member.service.MemberService?anyhost=true&application=futureloan-member-service&dubbo=2.5.3&interface=com.lemon.member.service.MemberService&methods=add,recharge,getMember,update,list,withdraw&pid=2333&retries=3&revision=0.0.1-SNAPSHOT&side=provider×tamp=1619651401859
调用接口的方法：invoke 接口.方法()
dubbo>invoke com.lemon.member.service.MemberService.list()
list方法
2.使用jmeter
将jmeter-plugins-dubbo-2.7.3-jar-with-dependencies.jar放入libext中后，重启Jmeter
添加「取样器」后可以看到增加了「Dubbo Sample」
取样器
在「Registry Settings」填入服务器信息后点击「Get Provider List」
填写
可以看到我们可以查看相关方法。这些方法与刚才使用Telnet查看的一致
查看方法
我们选择「list」后点击运行
可以在「查看结果树」中查看与Telnet中一致的内容
查看结果
查看add的接口文档
add接口文档
入参
其他性能测试工具
ab和wrk都是快速响应性能测试工具
wrk
