Set<String> keySet = stringRedisTemplate.keys("keyprefix:"+"*");
* 任意多个字符
? 单个字符
[] 括号内的某1个字符
org.springframework.data.redis.core.RedisTemplate
public Set<K> keys(K pattern) {
byte[] rawKey = rawKey(pattern);
Set<byte[]> rawKeys = execute(connection -> connection.keys(rawKey), true);
return keySerializer != null ? SerializationUtils.deserialize(rawKeys, keySerializer) : (Set<K>) rawKeys;
}
可以通过count参数设置扫描的范围
Set<String> keys = new LinkedHashSet<>();
stringRedisTemplate.execute((RedisConnection connection) -> {
try (Cursor<byte[]> cursor = connection.scan(
ScanOptions.scanOptions()
.count(Long.MAX_VALUE)
.match(pattern)
.build()
)) {
cursor.forEachRemaining(item -> {
keys.add(RedisSerializer.string().deserialize(item));
});
return null;
} catch (Exception e) {
throw new RuntimeException(e);
}
});
String key = "noteUserListenedPoi:*";
redisTemplate.delete(key);
LOGGER.info("redis中用户收听历史被清空");
后来测试发现模糊查询是可以用的, 删除改成
Set<String> keys = redisTemplate.keys("noteUserListenedPoi:" + "*");
redisTemplate.delete(keys);
LOGGER.info("{}, redis中用户收听历史被清空"
以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
