SpringCloud之使用Zookeeper作为注册中心

linux安装zookeeper

安装zookeeper

• 关闭linux防火墙
• 启动zookeeper

1 创建项目导入依赖和配置文件

<?xml version="1.0" encoding="UTF-8"?>

    
        mscloud03
        com.atguigu.springcloud
        1.0-SNAPSHOT
    
    4.0.0

    cloud-provider-payment8004


    
        
        
            org.springframework.boot
            spring-boot-starter-web
        
        
            com.atguigu.springcloud
            cloud-api-commons
            ${project.version}
        
        
        
            org.springframework.cloud
            spring-cloud-starter-zookeeper-discovery
        
        
            org.springframework.boot
            spring-boot-devtools
            runtime
            true
        
        
            org.projectlombok
            lombok
            true
        
        
            org.springframework.boot
            spring-boot-starter-test
            test
        
    

2 编写yaml

#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  # 您的linux服务器地址  ifconfig查看
 

3 编写启动类

@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);
    }

}

4 controller

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

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

出现的问题：

解决zookeeper版本jar包冲突问题

• zk 版本和springcloud的zk版本不一致
• 一般采用排除自带的zk版本 使用自己的zk

修改pom

                    zookeeper
                
            
         
        
        
            org.apache.zookeeper
            zookeeper
            3.4.9
        
        
            org.springframework.boot

            org.projectlombok
            lombok
            true
        
        
            org.springframework.boot
            spring-boot-starter-test
            test
        
    

5 测试
