Can anyone suggest how to fix the gap at the legacy system design?

1. The column is defined at the Java source code side as

   @Column(name="ID")
   @Type(type="string")
   private UUID id;
   

2. The column datatype on the database side is defined as datatype VARCHAR(36)

   Of course – we have an issue, because Hibernate can’t convert string to UUID automatically.

3. Databases’ changes are more comfortable as of now (cheaper) than Java source code.

Are there any ways how to avoid the issue with converting?

I’ve tried:

• change the database datatype to UUID; and
• set the value NULL to the column for all records (Hibernate has loaded a 0 records in this case).
