How to set password for redis cluster with spring boot 2.x

Question

“sorry, my English isn't very good”.

this is my redis config class:

@Component
@ConfigurationProperties(prefix = "spring.redis.cluster")
@Data
public class RedisClusterProperties {
    List<String> nodes;
}

---

@Configuration
public class RedisConfig {

@Autowired
RedisClusterProperties redisClusterProperties;

@Bean
public  RedisConnectionFactory connectionFactory(){
    return  new JedisConnectionFactory(
            new RedisClusterConfiguration(redisClusterProperties.getNodes()));
    }
}

next is my application.properties

spring.redis.cluster.nodes[0] = *.*.*.*:7001
spring.redis.cluster.nodes[1] = *.*.*.*:7002
spring.redis.cluster.nodes[2] = *.*.*.*:7003
spring.redis.cluster.nodes[3] = *.*.*.*:7004
spring.redis.cluster.nodes[4] = *.*.*.*:7005
spring.redis.cluster.nodes[5] = *.*.*.*:7006

next is my test-class

@Component
@Slf4j
public class TestRedis {
    @Autowired
    RedisConnectionFactory connectionFactory;

    @Scheduled(cron = "0 26 18 ? * *")
    public void scheduler(){
        RedisClusterConnection connection = 
connectionFactory.getClusterConnection();
    
connection.set("java_test".getBytes(),"java_test_value".getBytes());
        final byte[] bytes = connection.get("java_test".getBytes());
        System.out.println("print >> " + new String(bytes));
    }
}

then I start my project from application.class.it's normal that I can get /set data from my redis cluster.

Now I set a password for my redis cluster like this: I update my every redis.conf in linux.

update redis.conf for add password

Then I add ↓↓↓↓ to application.properties in my java project.

spring.redis.password=*****

I verify redis that it's can use normal. redis normal picture

Then I start my project and find that project is error.

I try to find method from here that how to deploy . but it's mistake. I try from reference with spring data here . but I can't find method.

please ask Who has met this problem. Thanks.

Try to set your password in a RedisClusterConfiguration in your RedisConfig configuration class:

@Bean
public  RedisConnectionFactory connectionFactory(){

    RedisClusterConfiguration clusterConf = 
        new RedisClusterConfiguration(
            redisClusterProperties.getNodes());

    clusterConf.setPassword(RedisPassword.of("yourPassword"));

    return new JedisConnectionFactory(clusterConf);
}
