在resources文件夹下创建application.yml文件

server:port: 8761 #设置Eureka服务器的端口号为8761
eureka:instance:hostname: localhost #指定Eureka实例的主机名为localhostclient:fetch-registry: false #禁用Eureka客户端从服务注册表中获取信息register-with-eureka: false # 禁止Eureka客户端向Eureka服务器注册自身service-url:defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka # 设置Eureka客户端连接到Eureka服务器的默认URL

@Setter
@Getter
@ConfigurationProperties(prefix = "redis")
public class RedisProperties {//主机private String host;//端口private int port;private int timeout;private String password;
