Spring Redis auto-configuration example

Spring Boot provides auto-configuration for Redis. You can make use of the other projects, but you must configure them yourself. Refer to the appropriate reference documentation at spring.io/projects/spring-data.

Redis

Redis is a cache, message broker, and richly-featured key-value store. Spring Boot offers basic autoconfiguration
for the Lettuce and Jedis client libraries and the abstractions on top of them provided
by Spring Data Redis.
There is a spring-boot-starter-data-redis “Starter” for collecting the dependencies in a convenient
way. By default, it uses Lettuce. That starter handles both traditional and reactive applications.

Connecting to Redis

You can inject an auto-configured RedisConnectionFactory, StringRedisTemplate, or vanilla
RedisTemplate instance as you would any other Spring Bean. By default, the instance tries to connect
to a Redis server at localhost:6379. The following listing shows an example of such a bean:

@Component
public class MyBean {
private StringRedisTemplate template;
@Autowired
public MyBean(StringRedisTemplate template) {
this.template = template;
}
// ...
}

You can also register an arbitrary number of beans that implement
LettuceClientConfigurationBuilderCustomizer for more advanced customizations.
If you use Jedis, JedisClientConfigurationBuilderCustomizer is also available.


If you add your own @Bean of any of the auto-configured types, it replaces the default (except in the
case of RedisTemplate, when the exclusion is based on the bean name, redisTemplate, not its type). By default, if commons-pool2 is on the classpath, you get a pooled connection factory.
