Hello I am trying to make a table in MySQL using Spring Boot and JPA and I am trying to make one of the columns in the table be a Java Class aka a JSON object is there any way I could do this and is there any examples or documentation for this solution.
Example of Table that I made
import com.project.something.here.Userdata
@Entity
@Table(name = "User")
public class Exercises {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private String id;
@Column(name = "user_name")
private String username;
@Column(name = "user_description")
private String userdescription;
@Column(name = "user_link")
private String userlink;
//here is where I am trying to set one of the columns as a Java class or a JSON object.
private Userdata userdata;
I believe you are more looking with one-to-one mapping in JPA. Please have a look : https://www.baeldung.com/jpa-one-to-one
Please have a look if that helps you.
import com.project.something.here.Userdata;
@Entity
@Table(name = "User")
public class Exercises {
// ...
@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(unique = true)
private Userdata userdata;
// ...
}
Userdata.java
@Entity
@Table(name = "userdata")
public class Userdata {
@Id
@Column(name = "id")
private Long id;
//...
@OneToOne(mappedBy = "userdata")
private Exercises exercises;
//... getters and setters
}
