I am new to Redis and using Spring Boot + Spring Data Redis example. In this example, I used the QueryByExampleRedisExecutor on repository method and used the Example API to do the custom query.
The following is the KEYS present in the Redis NoSQL DB.
redis 127.0.0.1:6379> KEYS *
1) "country:76c78bcc-bb2a-41b3-a1fc-3dbb3042edd6:idx"
2) "country:76c78bcc-bb2a-41b3-a1fc-3dbb3042edd6"
3) "user:lastName:Kerr"
4) "user"
5) "user:role.roleName:API"
6) "country:countryName:India"
7) "Student:name:John Doe"

redis 127.0.0.1:6379>
Repository method -
Example example = Example.of(User.builder().firstName("Mike").build());
long count = userRepository.count();
System.out.println(count);
When I execute the below method I was expecting to get only one result, but I am getting two count. Why ?
More Info shown here: Consider revisiting the entries above or defining a bean of type 'org.springframework.data.redis.core.RedisTemplate' in your configuration
How can we see the Redis snippet on the logs ? What configuration do I need to set ?
public interface UserRepository extends CrudRepository, QueryByExampleExecutor{
List findByFirstName(String firstName);
List findByFirstNameAndLastName(String firstName, String lastName);
@Query("SELECT u FROM User u WHERE u.middleName LIKE :middleName ")
List findCustomByMiddleName(@Param("middleName") String middleName);
List findByRole_RoleName(String roleName);
}
Error below for reference -
