Question

I have Spring Redis working using spring-data-redis with all default configuration likes localhost default port and so on.

Now

Answer 1

Upon looking deeper I found this, could it be what you are looking for?

# REDIS (RedisProperties)
spring.redis.database=0 # Database index used by the connection factory.
spring.redis.host=localhost # Redis server host.
spring.redis.password= # Login password of the redis server.
spring.redis.pool.max-active=8 # Max number of connections that can be allocated by the pool at a given time. Use a negative value for no limit.
spring.redis.pool.max-idle=8 # Max number of "idle" connections in the pool. Use a negative value to indicate an unlimited number of idle connections.
spring.redis.pool.max-wait=-1 # Maximum amount of time (in milliseconds) a connection allocation should block before throwing an exception when the pool is exhausted. Use a negative value to block indefinitely.
spring.redis.pool.min-idle=0 # Target for the minimum number of idle connections to maintain in the pool. This setting only has an effect if it is positive.
spring.redis.port=6379 # Redis server port.
spring.redis.sentinel.master= # Name of Redis server.
spring.redis.sentinel.nodes= # Comma-separated list of host:port pairs.
spring.redis.timeout=0 # Connection timeout in milliseconds. 

Refernce:https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html Searchterm Redis

From what I can see the values already exist and are defined as

spring.redis.host=localhost # Redis server host.
spring.redis.port=6379 # Redis server port.

if you want to create your own properties you can look at my previous post in this thread.

This works for me :

@Configuration
@EnableRedisRepositories
public class RedisConfig {

    @Bean
    public JedisConnectionFactory jedisConnectionFactory() {
        RedisProperties properties = redisProperties();
        RedisStandaloneConfiguration configuration = new RedisStandaloneConfiguration();
        configuration.setHostName(properties.getHost());
        configuration.setPort(properties.getPort());

        return new JedisConnectionFactory(configuration);
    }

    @Bean
    public RedisTemplate<String, Object> redisTemplate() {
        final RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(jedisConnectionFactory());
        template.setValueSerializer(new GenericToStringSerializer<>(Object.class));
        return template;
    }

    @Bean
    @Primary
    public RedisProperties redisProperties() {
        return new RedisProperties();
    }

}

and properties file :

spring.redis.host=localhost
spring.redis.port=6379

@Autowired
private JedisConnectionFactory connectionFactory;

@Bean
JedisConnectionFactory connectionFactory() {
    return connectionFactory
}
