Unable to determine SQL type name for column 'option_type' of table 'account_options' because there is no type mapping for org.hibernate.type.SqlTypes code: 2000 (JAVA_OBJECT)

[rcbandit111]

I have the following code which I want to migrate to Spring Boot 3:

  @Column(name = "OPTION_TYPE")
  @Type(type = "org.hibernate.type.ClassType")
  private Class<T> clazz;

Example demo:

https://github.com/rcbandit111/jpa_class_store_migration_poc/blob/main/src/main/java/com/jpa/store/poc/EnumeratedAccountOption.java

I tried to use:

@Column(name = "OPTION_TYPE")
@JdbcTypeCode(SqlTypes.JAVA_OBJECT)
private Class<T> clazz;
I get this error:

I get error during startup:

Do you know what should be the proper way to implement this?

This is purely a Hibernate mapping problem and therefore off topic here.

I suggest asking on Stackoverflow.
