spring boot-dubbo-zookeeper

-------------- spring boot-dubbo-zookeeper -------------
1. 安装 zookeeper (windows),切换到 bin 目录下，zkServer.cmd 启动zk服务

2. 构建项目，provider pom.xml

2. server 端启动类
package org.boot.provider;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan(basePackages = {"org.boot.provider"})
public class ServerApplication {
   public static void main(String[] args) {
       SpringApplication.run(ServerApplication.class, args);
   }
}

3. 加载的应用的启动信息 application.properties
server.port=9090
spring.dubbo.application.name=provider
spring.dubbo.registry.address=zookeeper://127.0.0.1:2181
spring.dubbo.protocol.name=http
#spring.dubbo.protocol.name=dubbo
#spring.dubbo.protocol.port=20880

spring.dubbo.scan=org.boot.provider.services

4. 消费端 pom 文件
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

5. 消费端启动类

package org.boot.consumer.controller;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan({"org.boot.consumer"})
public class ConsumerApplication {

   public static void main(String[] args) {
       SpringApplication.run(ConsumerApplication.class, args);
   }
}

6. 消费端应用启动配置 application.properties
server.port=9091
spring.dubbo.application.name=consumer
spring.dubbo.registry.address=zookeeper://127.0.0.1:2181
spring.dubbo.scan=org.boot.consumer.third_server.dubbo

注：扫描路径是客户端第三方服务注册的service 包路径而非服务端包路径

7. 配置dubbo服务客户端service

package org.boot.consumer.third_server.dubbo;

import org.boot.provider.services.UserService;
import org.springframework.stereotype.Component;

import com.alibaba.dubbo.config.annotation.Reference;

@Component
public class UserServiceDubboClient {

   @Reference(version = "1.0.1")
   private UserService userService;

   public UserService getUserService() {
       return userService;
   }
}

8. 调用第三方服务 controller
package org.boot.consumer.controller;

import org.boot.consumer.third_server.dubbo.UserServiceDubboClient;
import org.boot.provider.domain.UserDto;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import com.alibaba.fastjson.JSON;

@RestController
public class ParentController {

   @Autowired
   private UserServiceDubboClient userServiceDubboClient;

   @GetMapping("helloHome")
   public String helloHome () {
       UserDto dto = userServiceDubboClient.getUserService().queryUserInfoById(1l);
       System.out.println(JSON.toJSONString(dto));
       return "hello Home 你好 China";
   }

}
