SpringBoot集成Dubbo分布式框架项目结构

1. 接口工程：存放实体bean和业务接口
2. 服务提供者：业务接口的实现类并将服务暴露且注册到注册中心，调用数据持久层
   • 添加依赖（dubbo、注册中心、接口工程）
   • 配置服务提供者核心配置文件
3. 服务消费者：处理浏览器客户端发送的请求，从注册中心调用服务提供者所提供的服务
   • 添加依赖（dubbo、注册中心、接口工程）
   • 配置服务消费者核心配置文件

接口工程

package com.dyf.dubbo.service;

/**
 * @author: dyf
 * @date: 2022/9/5 16:44
 * @version: 1.0
 */
public interface StudentService {

    /**
     * 学生总数
     * @return
     */
    int studentTotal();

}
