###服务别名----服务注册到注册中心名称
spring.application.name=zk-member
#zookeeper地址
spring.cloud.zookeeper.connect-string=127.0.0.1:2181

在启动类上加@EnableDiscoveryClient这个注册

然后先启动zookeeper再启动项目,然后打开zookeeper图形化客户端工具,就看到注册上来的服务了.

在启动项目的时候可能会报错,原因就是maven里导的zookeeper客户端和window启动的zookeeper版本不匹配导致的,我用的zookeeper是3.5.4的maven使用的2.1.2的

摘除原有的依赖,引入跟自己zookeeper版本相同的依赖就可以了

zookeeper是采用临时节点类型的,也就是当服务关闭后,等待一会儿心跳收不到了zookeeper就会把服务信息剔除掉,没有自我保护机制的.
