Storing entire object as json in Spring Data - spring-data

Question

I have the following domain object:
#Data
#Entity
public class Person {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String first;
private String last;
private Integer age;
private String json;
}
and a PersonRepository extends Repository<Person, Long>. What I would like is to store in a table that looks like this:
CREATE TABLE IF NOT EXISTS person
(
id SERIAL NOT NULL PRIMARY KEY,
json JSONB NOT NULL
);
Is there a way to override the way Spring Data reads and writes to/from the database? Ideally I'd use Jackson to convert the object to/from JSON.
Right now any operation complains that the fields on Person don't have a corresponding column in the table.

You can use hibernate-types lib by Vlad Mihalcea - one of Hibernate authors:
<dependency>
<groupId>com.vladmihalcea</groupId>
<artifactId>hibernate-types-52</artifactId>
<version>2.1.1</version>
</dependency>
Then you can update your entity like this:
#Data
#Entity
#TypeDef(name = "jsonb", typeClass = JsonBinaryType.class)
public class Person {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
//...
#Type(type = "jsonb")
#Column(columnDefinition = "jsonb", nullable = false)
private String json;
}
IMO it's better to use concrete object instead of String here, like this:
#Type(type = "jsonb")
#Column(columnDefinition = "jsonb", nullable = false)
private SomeObject json;
