redis怎么获取所有key

redisCacheService.keys(String pattern);

public static Set<String> getAllKey(String match,int count){
    //返回集
    Set<String> binKeys = new HashSet<>();
    //封装scan查询参数
    ScanParams param = new ScanParams().match(match).count(count);
    //获取查询对象
    RedisCacheServiceImpl redisCacheSer = (RedisCacheServiceImpl)RedisCacheService;
    JedisCluster jedisClu = redisCacheSer.getJedisCluster();
//getClueterNodes获取集群节点，从各个集群中获取值进行遍历
    jedisClu.getClusterNodes().values().stream().forEach(pool->{
        boolean done = false;//
        String cur = "0";//游标，以0开始，返回0代表一次结束
        try(Jedis jedisNode = pool.getResource()){
            while(!done){
                ScanResult<String> scanResult = jedisNode.scan(cur,param);
                cur = scanResult.getStringCursor();
                if("0".equals(cur){done=true};
                List<String> result = scanResult.getResult();
                result.foreach(data->{binKeys.add(data)});
            }
        }
    });
    return binKeys;
}
