Springboot+Dubbo+Zookeeper

一、版本与环境搭建：

写在前面：截至 2021-12-17 当前Dubbo最新包与Jdk 17还不适配 调试无果后采用Jdk jdk1.8.0\_311完成验证

1.Dubbo官网：[Apache Dubbo][]

2.Zookeeper官网：[Download][]

3.Centos7部署Docker参考：[菜鸟学院][Link 1]

安装完设置启动并设置开机自启：

systemctl start docker
    systemctl enable docker

4.Docker官网：[Docker][]

Centos7拉取Zookeeper命令,容器启动命令：

docker pull zookeeper:3.7.0

5.Linux服务器，百度云首次申领三个月免费试用：[百度云服务器][Link 2]

6.最终还是手动搭建了Zookeeper环境，地址如下，大概3个月内都能用：

zookeeper://106.12.148.211:2181

<table> 
 <thead> 
  <tr> 
   <th>springboot</th> 
   <th>2.6.1</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>dubbo</td> 
   <td>3.0.2.1</td> 
  </tr> 
  <tr> 
   <td>zookeeper</td> 
   <td>3.7.0</td> 
  </tr> 
  <tr> 
   <td>jdk</td> 
   <td>1.8.0_311</td> 
  </tr> 
 </tbody> 
</table>

服务器如下：

二、聚合项目 RPC调用

项目结构，先上图：

启动服务，调用测试：

http://127.0.0.1:8090/test/hello?name=hongxu\_moon
