How to set redis client resource in Spring Boot 2.5.9?

[devsungmin]

Hello.

I'm going to set up redis in springboot environment using lettuce.
We used the previous version of lettuce 5.3.7 to set up the project as follows.

I proceeded to set up the project by referring to the official document of AWS.

@Bean
    fun redisClientResources(): ClientResources {
        return DefaultClientResources.builder()
            .dnsResolver(DirContextDnsResolver())
            .reconnectDelay(
                Delay.fullJitter(
                    Duration.ofMillis(100),
                    Duration.ofSeconds(10),
                    100, TimeUnit.MILLISECONDS
                )
            )
            .build()
    }

However, in the process of setting up a new project, it was discovered that the version of lettuce was changed to 6.1.6 and that the dnsResolver() was Deprecated.

Could you tell me which method I should use to use the above settings in 6.1.6 version?

The DNS resolver is deprecated because it resolves IP addresses synchronously. If you're good with JVM defaults regarding DNS resolution, there's no need to have a custom DNS resolver object. If you need customization, then you can either continue using Lettuce's DNS config mechanism or you can switch to netty's AddressResolverGroup for non-blocking DNS resolution.

Thank you @mp911de 😄
Your answer was very helpful for me to develop the application.
