springboot整合redis -Lettuce

1. 以单机版redis为例，安装redis参考文档：redis单机安装

2. 引入依赖

   <dependency>
       <groupId>io.lettuce</groupId>
       <artifactId>lettuce-core</artifactId>
   </dependency>
   

   • 版本号：6.3.0.RELEASE，springboot3.2.0中默认的lettuce-core版本

3. 示例，使用Lettuce连接单机版redis

   public class LettuceDemo {
   
       public static void main(String[] args) {
   
           // 1. 指定redis服务的ip和端口，账号和密码
           RedisURI uri = RedisURI.builder().withHost("192.168.145.132").withPort(6379).withAuthentication("default", "123456").build();
   
           // 2. 创建连接客户端
           RedisClient redisClient = RedisClient.create(uri);
           StatefulRedisConnection<String, String> connect = redisClient.connect();
   
           // 3. 通过connect创建操作的command
           RedisCommands<String, String> commands = connect.sync();
   
           // keys
           List<String> keys = commands.keys("*");
           System.out.println(keys);
   
           // string
           String status = commands.set("k5", "hello-lettuce");
           System.out.println(status); // OK
   
           String k5 = commands.get("k5");
           System.out.println(k5);
   
           Boolean aBoolean = commands.expire("k5", 20L);
           System.out.println(aBoolean); // true
   
           // list
           commands.del("myList1");
   
           Long count1 = commands.lpush("myList1", "v1", "v2", "v3");
           System.out.println(count1); // 列表大小
   
           List<String> list = commands.lrange("myList1", 0, -1);
           System.out.println(list); // [v3, v2, v1]
   
           // hash
           commands.del("myHash1");
   
           commands.hset("myHash1", "name", "zhangsan");
   
           Map<String, String> map = new HashMap<>();
           map.put("id", "001");
           map.put("age", "20");
           commands.hset("myHash1", map);
   
           String name = commands.hget("myHash1", "name");
           System.out.println(name);
   
           List<KeyValue<String, String>> hashList = commands.hmget("myHash1", "id", "name");
           System.out.println(hashList); // [KeyValue[id, 001], KeyValue[name, zhangsan]]
   
           // set
           commands.del("mySet1");
   
           long count2 = commands.sadd("mySet1", "s1", "s2", "s3", "s3", "s2");
           System.out.println(count2); // 新增数
   
           Set<String> set = commands.smembers("mySet1");
           System.out.println(set); // [s2, s1, s3]
   
           // zset
           commands.del("myZset1");
   
           commands.zadd("myZset1", 60d, "v1");
           commands.zadd("myZset1", 70d, "v2");
           commands.zadd("myZset1", 80d, "v3");
           commands.zadd("myZset1", 80d, "v4");
           commands.zadd("myZset1", 90d, "v5");
   
           List<String> zsetList = commands.zrangebyscore("myZset1", 80d, 90d);
           System.out.println(zsetList); // [v3, v4, v5]
   
           // 4. 各种关闭释放资源
           connect.close();
           redisClient.shutdown();
       }
   }
