搭建springboot+dubbo+zookeeper+mybatis具体操作：（注意必须启动zookeeper服务哦！）

**一、打开IDE创建springboot父项目demo,再新建三个module:**

1. dubbo-api(对外RPC接口)

2. dubbo-provider(dubbo接口提供者)

3. dubbo-customer(dubbo接口消费者)  
如图所示:

**二、 父项目demo的pom.xml文件的配置**

**三、 3个子项目相关配置与文件**

3.1 dubbo-api(对外RPC接口) -->主要放实体、接口、也可以放一些公用的工具类工程

业务接口

3.2 dubbo-provider(dubbo接口提供者) -->主要是服务提供者

mapper接口:

    import org.apache.ibatis.annotations.Result;
    import org.apache.ibatis.annotations.Results;
    import org.apache.ibatis.annotations.Select;
    
    import java.util.List;
    
    /**
     * 底层数据UserinfoMapper接口
     */
    @Mapper   //扫描注入bean
    public interface UserinfoMapper {
    
        @Select("select * from userinfo")
        @Results(value = {
                @Result(property = "id", column = "id"),
                @Result(property = "userCode", column = "userCode"),
                @Result(property = "userName", column = "userName"),

        @Select("select * from userinfo where id=#{id}")
        public Userinfo findById(Integer id);
    
    }

实现接口的业务类
