Redis configuration in spring boot to store and retrieve objects stored in redis cache that can have lists and Date objects as fields.

Answer 1

A Redis hash is a data type that represents a mapping between a string field and a string value which you can convert as list of any type of data

@RedisHash("User")
@Getter
@Setter
public class Student implements Serializable {

    private String userId;
    private String name;
    private int age;
  }

and then call it on repository

User user = User().builder.id("testUser").name("testName").age(20).expiration(86400).build(); userRepository.save(user);

You can also easily do this with Redis based framework - Redisson. It offers wrapped collections like java.util.List, java.util.Set, java.util.Map and many more.

Config config = ...
RedissonClient redisson = Redisson.create(config);
List<String> list = redisson.getList("myList");
list.add("1");
list.add("2");
list.add("3");

list.remove("2")
