I am developing Spring Data Redis example with Spring Boot. In this example, I am looking to store all keys and values as json format. Using CrudRepository pattern to perform CRUD operations. Do I need to set any configurations to that keys can be stored as JSON ? I went through the link : https://docs.spring.io/spring-data/data-redis/docs/current/reference/html/, but not clear where to set confogurations.
