Dubbo+zookeeper搭配分布式服务的过程详解
目录
分布式架构：
1.当垂直应用越来越多，应用之间交互不可避免，将核心业务抽取出来，作为独立的服务，逐渐形成稳定的服务中心，前端应用能更快速的响应多变的市场需求。
2.此时，用于提高业务复用及整合的 分布式服务框架(RPC) 是关键。
Dubbo 是什么
Dubbo:
作为分布式架构比较后的框架，同时也是比较容易入手的框架，适合作为分布式的入手框架，下面是简单的搭建过程
工具:idea+tomact+zookeeper (知识点:jsp,spring,springmvc,maven)
思想：
依赖：
工程分布：
provider实现interface提供服务,constomer消费provider提供的服务
interface:
package com.atchengdu.serviceinterface;
import com.atchengdu.pojo.User;
public interface Userservice {
//获取user的信息
User getuserByid(Integer ie);
}
package com.atchengdu.pojo;
import java.io.Serializable;
public class User implements Serializable {
private Integer id ;
private String name;
public User(Integer id, String name) {
this.id = id;
this.name = name;
}
public User() {
public Integer getId() {
return id;
public void setId(Integer id) {
public String getName() {
return name;
public void setName(String name) {
@Override
public String toString() {
return "User{" +
"id=" + id +
", name='" + name + ''' +
'}';
provider：
package com.atchengdu.Modulserviceimpl;
import com.atchengdu.pojo.User;
import com.atchengdu.serviceinterface.Userservice;
public class Userserviceimpl implements Userservice {
@Override
public User getuserByid(Integer ie) {
User user=new User(1,"张三");
return user;
}
}
