Implementation of Redis query keys error report

ERR unknown command keys

After switching to redis, I found an error in the keys command. The reason for query is as follows:

The reason may be: the keys command is used for global query. It is generally not recommended to use it, so the replacement command can be configured.

Solution: Check if this command is in the configuration disabled
rename-command FLUSHALL ""  Clear all library data
rename-command FLUSHDB ""                                                                                                                                                                 �
rename-command KEYS ""

If there is comment,

However, because it is using a unified deployment redis, it is impossible to modify the operation, so it has to modify the operation involving the kes command

Use scan to get redisKey

@Autowired
public RedisTemplate redisTemplate;

public Set<String> scan(String matchKey) {
	Set<String> keys = new HashSet<>();
	ScanOptions scanOptions = ().match(matchKey).count(1000).build();
	Cursor<byte[]> cursor = (Cursor<byte[]>) (redisConnection -> (scanOptions), true);
	RedisSerializer redisSerializer = ();
	while (()) {
		(((())));
	}
	return keys;
}
