在集群的情况下，用户多次请求接口时，存入的内容可能会导致重复，这时候就可以使用分布式锁来限制

适用场景

分布式应用，分布式缓存，分布式回话管理，分布式服务（任务，延迟任务，执行器），分布式redis客户端

第一步：导入依赖

第二步：配置连接redis

程序化配置方法

验证是否连接成功

结果

{"singleServerConfig":{"idleConnectionTimeout":10000,"pingTimeout":1000,"connectTimeout":10000,"timeout":3000,"retryAttempts":3,"retryInterval":1500,"reconnectionTimeout":3000,"failedAttempts":3,"subscriptionsPerConnection":5,"address":"redis://127.0.0.1:6379","subscriptionConnectionMinimumIdleSize":1,"subscriptionConnectionPoolSize":50,"connectionMinimumIdleSize":10,"connectionPoolSize":64,"database":0,"dnsMonitoring":false,"dnsMonitoringInterval":5000},"threads":0,"nettyThreads":0,"codec":{"class":"org.redisson.codec.JsonJacksonCodec"},"codecProvider":{"class":"org.redisson.codec.DefaultCodecProvider"},"resolverProvider":{"class":"org.redisson.liveobject.provider.DefaultResolverProvider"},"redissonReferenceEnabled":true,"useLinuxNativeEpoll":false}
