zookeeper代替eureka与springcloud整合

1、创建服务

1.2 引入zookeeper依赖，代替eureka

    <artifactId>cloud-provider-payment8004</artifactId>

    <dependencies>

            <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>

        </dependency>
        <!--引入自定义的api通用包，可以使用payment支付Entity-->
        <dependency>
            <groupId>com.atguigu.springcloud</groupId>
            <artifactId>cloud-api-commons</artifactId>
            <version>${project.version}</version>
        </dependency>

        </dependency>
    </dependencies>
</project>

1.3 写application.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: 192.168.88.131:2181

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  //该注解用于想使用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);
    }
}

测试

package com.atguigu.springcloud.controller;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.UUID;

@RestController
@Slf4j
public class PaymentController {
    @Value("${server.port}")
    private String serverPort;

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

zookeeper-discovery自带zookeeper会发生版本冲突，所以要排除自带的zookeeper

<!--springboot整合zookeeper客户端-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
            <!--先排除自带的zookeeper3.5.3-->
            <exclusions>
                <exclusion>
                    <groupId>org.apache.zookeeper</groupId>
                    <artifactId>zookeeper</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <!--添加zookeeper3.4.14版本-->
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.14</version>
        </dependency>

PS： 新版本的zookeeper还会遇到slf4j和log4j包冲突的问题，此时在zookeeper去掉slf4j的依赖

<dependency>
	<groupId>org.apache.zookeeper</groupId>
    	<artifactId>zookeeper</artifactId>
        <version>3.4.14</version>
        <exclusions>
        	<exclusion>
            	<groupId>log4j</groupId>
                <artifactId>log4j</artifactId>
            </exclusion>
            <exclusion>
            	<groupId>org.slf4j</groupId>
                <artifactId>slf4j-log4j12</artifactId>
            </exclusion>
     </exclusions>
</dependency>
