Cannot connect to redis using spring and lettuce - spring-boot

Question

I am struggling to find what could be wring here; need help.
I am using spring-data-redis 2.4.1
RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration()
redisStandaloneConfiguration.setHostname(hostname)
redisStandaloneConfiguration.setPort(6379)
redisStandaloneConfiguration.setPassword("password")
I then create lettuceClientConfigurationBuilder and specify clientName
I then use lettuceClientConfiguration and redisStandaloneConfiguration to create ClientConnectionFactory.
However, when we call getConnection() on the connection Factory, we get
WrongPass Invalid username-password pair
The same set of username-password works with Redis-CLI on cmd prompt.
Is there is something wrong in the way I am using in my java application?
Any pointer/hint towards solving this would be greatly appreciated.

Answer 1

Spring Boot configures LettuceConnectionFactory for you, you can specify the connection params on the application.properties file.
spring.redis.database=0
spring.redis.host=localhost
spring.redis.port=6379
spring.redis.password=yourPassword
spring.redis.timeout=60000
If you wanna do it programmatically, set the spring.redis.password in application.properties and try this:
#Configuration
class AppConfig {
#Bean
public LettuceConnectionFactory redisConnectionFactory() {
return new LettuceConnectionFactory(new RedisStandaloneConfiguration("server", 6379));
}
}

Answer 2

I had mistaken username for clientname set on LettuceClientConfigurationBuilder but username had to be specified on the redisstandaloneconfiguratuon.
This works for me; also please note acl was introduced only after lettuce 2.4.1 so any prior version will not work.
redisStandaloneConfiguration.setUsername(connectionFactoryConfigs.getUserName());
