[FIXED] Why am I getting "NOAUTH Authentication required" with Spring Boot?

Issue

I have a simple redis server running with a password. I want to talk with it from my spring boot app. I look here and see there is a spring.redis.password so my application-local.yml (running with -Dspring.profiles.active=local) looks like...

spring:
  redis:
    password: ... 

but when I run I get

NOAUTH Authentication required

What am I missing? I can connect via node.js like...

import redis from "redis";

const client = redis.createClient({
 password: "..."
});

Additional Code

@Bean
LettuceConnectionFactory redisConnectionFactory(){
    RedisStandaloneConfiguration config = new RedisStandaloneConfiguration();
    return new LettuceConnectionFactory(config);
}

@Bean
public RedisTemplate<String, Object> redisTemplate(){
    RedisTemplate<String, Object> template = new RedisTemplate<>();
    template.setConnectionFactory(redisConnectionFactory());
    return template;
}

also tried...

@Bean
LettuceConnectionFactory redisConnectionFactory(){
    RedisStandaloneConfiguration config = new RedisStandaloneConfiguration();
    if (redisPassword != null){
        config.setPassword(redisPassword);
    }
    return new LettuceConnectionFactory(config);
}

and this works but seems overly verbose given it is a standard property.

Solution

If you need less verbose configuration, you can remove RedisConnectionFactory bean from your configuration code and just inject the RedisConnectionFactory bean in your redisTemplate. redisConnectionFactory will be populated with properties from application.yml:

@Bean
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
    RedisTemplate<String, Object> template = new RedisTemplate<>();
    template.setConnectionFactory(redisConnectionFactory);
    return template;
}

In this case, Spring injects LettuceConnectionFactory by default.

The problem was here: new RedisStandaloneConfiguration(). If you look at the code of constructor you will see that empty password is created and there is no way to set it besides calling a setter.

Old answer: You need to fetch your data from application.yml through RedisProperties class. Try this:

@Bean
RedisConnectionFactory redisConnectionFactory(RedisProperties props) {
    RedisStandaloneConfiguration config = new RedisStandaloneConfiguration();

    config.setPassword(props.getPassword());

    return new LettuceConnectionFactory(config);
}

@Bean
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
    RedisTemplate<String, Object> template = new RedisTemplate<>();
    template.setConnectionFactory(redisConnectionFactory);
    return template;
}

Here props contains properties from spring.redis section
