How to set redis databse number to be used in spring boot

Question

In my application and I want all my keys to go to a specific database number.

I checked Redis documentation and found that Redis has 16 databases by default 0-15.

Let's say I want to use database 3.

How can I do it in java spring-boot application?

Answer 1

You can specify that in the application.properties file like this.

spring.redis.database=3

after this while creating Jedisconnection factory set this databse to jedisconnectionfactory.

    @Autowired
    private RedisProperties redisProperties;


    @Bean
    JedisConnectionFactory jedisConnectionFactory() {

        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(redisSentinelConfiguration);
        jedisConnectionFactory.setDatabase(this.redisProperties.getDatabase());
        return jedisConnectionFactory;
    }
