1.新建服务提供者

新建service

package com.example.service;

/**
 * @author shihy
 * @date 2021/1/10 11:33
 * @description
 */
public interface TicketService {
    public String getTicket();
}

实现类:

package com.example.service;

import org.apache.dubbo.config.annotation.Service;
import org.springframework.stereotype.Component;

/**
 * @author shihy
 * @date 2021/1/10 11:34
 * @description
 */
@Component
@Service
public class TicketServiceImpl implements TicketService {
    @Override
    public String getTicket() {
        return "dubbo+zookeeper";
    }
}

• @service要引用duubo的
• @compoent 使用spring的自动注入

application.properties

server.port=8001
dubbo.application.name=provider-server
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.scan.base-packages=com.example.service

• 提供者不需要引用api模块

2.新建api模块

主要提供与服务提供者一样的接口层次

3.建服务调用方

package com.example.service;

import org.apache.dubbo.config.annotation.Reference;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author shihy
 * @date 2021/1/10 11:38
 * @description
 */
@Service
@RestController
public class UserService {

    @Reference
    TicketService ticketService;

    @RequestMapping("/buy")
    public void  buyTicker(){
        String ticker = ticketService.getTicket();
        System.out.println("拿到了"+ticker);
    }
}
