一、配置文件添加eureka相关配置：
eureka.client.serviceUrl.defaultZone = http\://192.168.1.176\:8761/eureka/
eureka.client.healthcheck.enabled = true
#开启健康检查（需要spring-boot-starter-actuator依赖）
eureka.instance.preferIpAddress = true
# 将Instance ID设置成IP:端口的形式
eureka.instance.instance-id = ${spring.cloud.client.ipAddress}:${server.port}
eureka.instance.statusPageUrlPath = ${server.context-path:${SERVER_CONTEXTPATH:}}${management.context-path:${MANAGEMENT_CONTEXTPATH:}}${endpoints.info.path:/manager/login/loginIn}
eureka.instance.healthCheckUrlPath = ${server.context-path:${SERVER_CONTEXTPATH:}}${management.context-path:${MANAGEMENT_CONTEXTPATH:}}${endpoints.health.path:/health}
# 续约更新时间间隔（默认30秒）
eureka.instance.lease-expiration-duration-in-seconds = 10
# 续约到期时间（默认90秒）:到期后自动注销注册（此时在服务端看不到该服务），然后重新注册服务
eureka.instance.lease-renewal-interval-in-seconds = 5
二、在pom.xml文件中引入eurekaClient依赖jar包
<!-- Spring Cloud Config Client -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-client</artifactId>
</dependency>
三、启动类添加eurekaClient的相关注解@EnableCasClient //cas client客户端
