分布式服务框架之Dubbo整合Spring项目（一）
先说一下架构，项目采用Maven管理依赖，总共三个项目，一个是接口包common-inter，一个是服务提供者provider，最后一个是服务消费者cunsumer。
common-inter：主要是各类服务的接口，和接口相关的类，比如Bean或者通用工具等。
provider：服务提供者，采用mybaties+spring框架，当然服务本身也可以作为一个MVC项目，只需要加入框架即可。
cunsumer：服务消费者，采用spring+springMVC架构。
项目非分布式部署。
需求：这里做一个简单的注册、列表和查看三个功能。
下图是eclipse中项目结构：
项目搭建完成后，还需要启动zookeeper，zookeeper是用来注册服务的，下载地址。
下载完成后，解压。用cmd命令找到解压后的文件夹，打开bin，找到zkServer.cmd，运行（详细步骤请百度，这里不做细讲）。下面是运行截图：
最小化他，切忌不可关闭。回到eclipse，找到接口项目，建立接口
public interface IUserService {
public void insert(User user);
public User getUserById(Integer id);
public List<User> getUsers();
}
User.java
public class User implements Serializable{
/**
*
*/
private static final long serialVersionUID = -7064020898680071328L;
private Integer id;
private String uname;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUname() {
return uname;
}
public void setUname(String uname) {
this.uname = uname;
}
}
接口编写完毕，另外两个项目引入即可。
先说服务项目：
