Spring-Cloud集成redis-cluster

前言

系统之前接入的是单点redis，为了条系统高可用能力，特增加集成redis-cluster集群的步骤

依赖库引入

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

启动类配置

@EnableScheduling
@EnableCaching
@MapperScan("com.haier.smarthome.intelligentfamilyconsole.mapper")
public class IntelligentFamilyConsoleApplication {

   public static void main(String[] args) {
      SpringApplication.run(IntelligentFamilyConsoleApplication.class, args);
   }

}
