Env variables in data class in Redis model annotation

Question

Troubling to specify dynamic env variable in the model class @Hashkey Redis annotation.

Model:

@RedisHash("${spring.redis.namespace}:Book")
public class Book {
    @Id
    private String id;
    private String name;
}

My application.properties file:

spring.redis.namespace=local

The resulting key is "${spring.redis.namespace}:Book" instead of local:Book

Could anyone help me with this?

Please use Keyspaces to do it. There two ways. I use one way to finish your requirement.

@Configuration
@EnableRedisRepositories(keyspaceConfiguration = MyKeyspaceConfiguration.class)
public class ApplicationConfig {

  @Value("${spring.redis.namespace}:Book")
  String myKey;

  //... RedisConnectionFactory and RedisTemplate Bean definitions omitted

  public static class MyKeyspaceConfiguration extends KeyspaceConfiguration {

    @Override
    protected Iterable<KeyspaceSettings> initialConfiguration() {
      return Collections.singleton(new KeyspaceSettings(Book.class, myKey));
    }
  }
}
