SpringCloud整合Zookeeper代替Eureka

# SpringCloud整合Zookeeper #

## 一、注册中心Zookeeper ##

--------------------

*  zookeeper是一个分布式协调工具，可以实现注册中心功能
 *  关闭Linux服务器防火墙后启动
 *  zookeeper服务器zookeeper服务器取代Eureka服务器，zk作为服务注册中心

## 二、服务提供者 ##

--------------------

### 1、新建Module ###

cloud-provider-payment8004

### 2、POM ###

### 3、YML ###

#8004表示注册到zookeeper服务器的支付服务提供者端口号
    server:
      port: 8004
    #服务别名----注册zookeeper到注册中心名称
    spring:
      application:
        name: cloud-provider-payment
      cloud:
        zookeeper:
          connect-string: 192.168.111.144:2181

### 4、主启动类 ###

package com.atguigu.springcloud;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    
    @SpringBootApplication
    @EnableDiscoveryClient //该注解用于向使用consul或者zookeeper作为注册中心时注册服务
    public class PaymentMain8004
    {
        public static void main(String[] args)
        {
            SpringApplication.run(PaymentMain8004.class,args);
        }
    
    }

### 5、Controller ###

package com.atguigu.springcloud.controller;
    
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    import org.springframework.beans.factory.annotation.Value;

        @Value("${server.port}")
        private String serverPort;
    
        @RequestMapping(value = "/payment/zk")
        public String paymentzk()
        {
            return "springcloud with zookeeper: "+serverPort+"\t"+ UUID.randomUUID().toString();
        }
    }

server:
      port: 80
    
    spring:
      application:
        name: cloud-consumer-order
      cloud:
      #注册到zookeeper地址
        zookeeper:
          connect-string: 192.168.111.144:2181

### 4、主启动 ###

package com.atguigu.springcloud;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class OrderZK80

        {
            SpringApplication.run(OrderZK80.class,args);
        }
    }

### 5、业务类 ###

**配置Bean**

config包下ApplicationContextBean.java

package com.atguigu.springcloud.config;
    
    import org.springframework.cloud.client.loadbalancer.LoadBalanced;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.client.RestTemplate;
    
    /**
     * @auther zzyy
     * @create 2020-01-30 17:33
     */
    @Configuration
    public class ApplicationContextBean
    {
        @Bean
        @LoadBalanced
        public RestTemplate getRestTemplate()
        {
            return new RestTemplate();
        }
    }

**Controller**

package com.atguigu.springcloud.controller;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    import org.springframework.web.client.RestTemplate;
    
    @RestController
    public class OrderZKController
    {
        public static final String INVOKE_URL = "http://cloud-provider-payment";
    
        @Autowired
        private RestTemplate restTemplate;
    
        @RequestMapping(value = "/consumer/payment/zk")
        public String paymentInfo()
        {
            String result = restTemplate.getForObject(INVOKE_URL+"/payment/zk", String.class);
            System.out.println("消费者调用支付服务(zookeeper)--->result:" + result);
            return result;
        }
    
    }

**验证测试**

# Consul服务注册与发现 #

## 一、Consul简介 ##

--------------------

[What is Consul? | Consul | HashiCorp Developer][What is Consul_ _ Consul _ HashiCorp Developer]

> Consul 是一套开源的分布式服务发现和配置管理系统，由 HashiCorp 公司用 Go 语言开发。
> 
> 提供了微服务系统中的服务治理、配置中心、控制总线等功能。这些功能中的每一个都可以根据需要单独使用，也可以一起使用以构建全方位的服务网格，总之Consul提供了一种完整的服务网格解决方案。
> 
> 它具有很多优点。包括： 基于 raft 协议，比较简洁； 支持健康检查, 同时支持 HTTP 和 DNS 协议 支持跨数据中心的 WAN 集群 提供图形界面 跨平台，支持 Linux、Mac、Windows

Spring Cloud Consul 具有如下特性：

![e9babd344e444e4d8fd8d8f37b498e36.png][]

>  *  服务发现----提供HTTP和DNS两种发现方式。
>  *  健康监测----支持多种方式，HTTP、TCP、Docker、Shell脚本定制化
>  *  KV存储----监控Key、Value的存储方式
>  *  多数据中心----Consul支持多数据中心
>  *  可视化Web界面

下载地址[ Install | Consul | HashiCorp Developer][Install _ Consul _ HashiCorp Developer]

文档 [Spring Cloud Consul 中文文档 参考手册 中文版][Spring Cloud Consul _ _]

## 二、安装并运行Consul ##

--------------------

官网安装说明 [Deploy Consul server | Consul | HashiCorp Developer][Deploy Consul server _ Consul _ HashiCorp Developer]

下载完成后只有一个consul.exe文件，硬盘路径下双击运行，查看版本号信息

![3f51926285e74404b161553b8f0f72e6.png][]

使用开发模式启动

> \#cmd命令窗口执行命令
> 
> consul agent -dev

通过以下地址可以访问Consul的首页：http://localhost:8500

### 3、YML ###

###consul服务端口号
    server:
      port: 80
    
    spring:
      application:
        name: cloud-consumer-order
    ####consul注册中心地址
      cloud:
        consul:
          host: localhost
          port: 8500
          discovery:
            #hostname: 127.0.0.1
            service-name: ${spring.application.name}

### 4、主启动类 ###

package com.atguigu.springcloud;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    
    @SpringBootApplication
    @EnableDiscoveryClient //该注解用于向使用consul或者zookeeper作为注册中心时注册服务
    public class OrderConsulMain80
    {
        public static void main(String[] args)
        {
            SpringApplication.run(OrderConsulMain80.class,args);
        }
    }

### 5、配置Bean ###

config包下ApplicationContextBean.java

package com.atguigu.springcloud.config;
    
    import org.springframework.cloud.client.loadbalancer.LoadBalanced;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.client.RestTemplate;
    
    @Configuration
    public class ApplicationContextBean
    {
        @Bean
        @LoadBalanced
        public RestTemplate getRestTemplate()
        {
            return new RestTemplate();
        }
    }

### 6、Controller ###

package com.atguigu.springcloud.controller;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    import org.springframework.web.client.RestTemplate;
    
    @RestController
    public class OrderConsulController
    {
        public static final String INVOKE_URL = "http://cloud-provider-payment"; //consul-provider-payment
    
        @Autowired
        private RestTemplate restTemplate;
    
        @GetMapping(value = "/consumer/payment/consul")
        public String paymentInfo()
        {
            String result = restTemplate.getForObject(INVOKE_URL+"/payment/consul", String.class);
            System.out.println("消费者调用支付服务(consule)--->result:" + result);
            return result;
        }
    }

### 验证测试 ###

#  #

# 三个注册中心异同点 #

--------------------

## CAP ##

> **C:Consistency（强一致性）**
> 
> **A:Availability（可用性）**
> 
> **P:Partition tolerance（分区容错性）**
> 
> **CAP理论关注粒度是数据，而不是整体系统设计的策略**

## 经典CAP图 ##

> 最多只能同时较好的满足两个。
> 
>  CAP理论的核心是：一个分布式系统不可能同时很好的满足一致性，可用性和分区容错性这三个需求，
> 
> 因此，根据 CAP 原理将 NoSQL 数据库分成了满足 CA 原则、满足 CP 原则和满足 AP 原则三 大类：
> 
> CA - 单点集群，满足一致性，可用性的系统，通常在可扩展性上不太强大。
> 
> CP - 满足一致性，分区容忍必的系统，通常性能不是特别高。
> 
> AP - 满足可用性，分区容忍性的系统，通常可能对一致性要求低一些。
