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：
