when I restart redis cause
java.util.concurrent.ExecutionException: io.lettuce.core.RedisCommandExecutionException: NOAUTH Authentication required. Why is this a problem use version like this

@Configuration
public class RedisConfig {

    @Autowired
    private RedisProperties redisProperties;

    @Bean(destroyMethod = "close")
    public StatefulRedisConnection<String, Object> StatefulRedisConnection() {
        RedisURI redisUri = RedisURI.builder().withPassword(redisProperties.getPassword())
                .withSentinel(redisProperties.getSentinel().getNodes().get(0).split(":")[0],
                        Integer.valueOf(redisProperties.getSentinel().getNodes().get(0).split(":")[1]))
                .withSentinelMasterId(redisProperties.getSentinel().getMaster())
                .withDatabase(redisProperties.getDatabase()).build();
        RedisClient redisClient = RedisClient.create(redisUri);
        return redisClient.connect(new SerializedObjectCodec());
    }
}

public class CacheImpl implements Cache {
    @Autowired
    private StatefulRedisConnection connect;

    public Boolean addCourseInfosCache() {
        RedisAsyncCommands<String, Object> commands = connect.async();
        // disable auto-flushing
        commands.setAutoFlushCommands(false);
        List<RedisFuture<?>> futures = Lists.newArrayList();
        commands.flushCommands();
    }
}

Lettuce leverages a custom syntax for Redis URIs. This is the schema:

redis :// [password@] host [: port] [/ database]
  [? [timeout=timeout[d|h|m|s|ms|us|ns]]
  [&_database=database_]]

There are four URI schemes:

  • redis – a standalone Redis server
  • rediss – a standalone Redis server via an SSL connection
  • redis-socket – a standalone Redis server via a Unix domain socket
  • redis-sentinel – a Redis Sentinel server

The Redis database instance can be specified as part of the URL path or as an additional parameter. If both are supplied, the parameter has higher precedence.

Print your redis uri connection string and check with your inputs.

You can upgrade Lettuce version and try:

RedisURI redisUri = RedisURI.Builder.sentinel("sentinelhost1", "mymaster").withPassword("abc").build();
