Dubbo+zookeeper搭配分布式服务的方法

本文小编为大家详细介绍“Dubbo+zookeeper搭配分布式服务的方法”，内容详细，步骤清晰，细节处理妥当，希望这篇“Dubbo+zookeeper搭配分布式服务的方法”文章能帮助大家解决疑惑，下面跟着小编的思路慢慢深入，一起来学习新知识吧。

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

• 一款分布式服务框架

• 高性能和透明化的RPC远程服务调用方案

• SOA服务治理方案

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：

<dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>5.2.5.RELEASE</version>
        </dependency>

        <!--zookeeper依赖-->

            <artifactId>001-interface</artifactId>
            <version>1.0-SNAPSHOT</version>

    </dependencies>

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;
    }
}
