SpringBoot+Dubbo+Zookeeper

ゝ一纸荒年。 2022-05-25 11:59 152阅读 0赞

**一、安装Zookeeper单机版（只用于demo，所以在Windows下安装）**

*  官网下载[http://zookeeper.apache.org/][http_zookeeper.apache.org]

**二、下载后解压，重命名，移至D:\\devsoft\\zookeeper**

**三、在D:\\devsoft\\zookeeper 新建data及log目录**

**四、到D:\\devsoft\\zookeeper\\conf 下复制 zoo\_sample.cfg 并粘贴到当前目录下，命名zoo.cfg**

**五、编辑zoo.cfg.修改如下配置**

**六、cmd命令下进入D:\\devsoft\\zookeeper\\bin目录下运行 zkserver.cmd**

**七、新建springboot-dubbo父工程，dubbo-provider、dubbo-consumer、dubbo-api子模块(dubbo-provider、dubbo-consumer依赖dubbo-api)**

**八、dubbo-api  创建接口UserService**

package com.zeke.dubboapi.service;
    
    public interface UserService {
    
        public String sayHello();
    }

**九、dubbo-provider创建接口实现UserServiceImpl**

package com.zeke.dubboprovider.service.impl;
    
    import com.alibaba.dubbo.config.annotation.Service;
    import com.zeke.dubboapi.service.UserService;
    
    @Service
    public class UserServiceImpl implements UserService {
        @Override
        public String sayHello() {
            return "success";
        }
    }

*  application.properties

server.port=7001
    #应用名称
    spring.dubbo.application.name=dubbo-provider
    #注册中心地址
    spring.dubbo.registry.address=zookeeper://10.0.0.36:2181
    #暴露服务方式
    spring.dubbo.protocol.name=dubbo
    #暴露服务端口
    spring.dubbo.protocol.port=20880
    #暴露服务包
    spring.dubbo.scan=com.zeke.dubboprovider.service.impl

**十、dubbo-consumer调用dubbo暴露的服务**

package com.zeke.dubboconsumer.controller;
    
    import com.alibaba.dubbo.config.annotation.Reference;
    import com.zeke.dubboapi.service.UserService;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class UserController {
    
        @Reference
        UserService userService;
    
        @GetMapping("/sayHello")
        public String sayHello() {
            String result = userService.sayHello();
            return result;
        }
    
    }

*  application.properties

server.port=7002
    #应用名称
    spring.dubbo.application.name=dubbo-consumer
    #注册中心地址
    spring.dubbo.registry.address=zookeeper://10.0.0.36:2181
    
    #路径
    spring.dubbo.scan=com.zeke.dubboconsumer.controller

**十一、分别启动dubbo-consumer和dubbo-provider，访问localhost:7002/sayHello**
