Enum in Hibernate, persisting as an enum
enums, hibernate, java, mysql, orm
Solution
My understanding is that MySQL enum type is very proprietary and not well supported by Hibernate, see this comment from Gavin King (this related issue is a bit different but that's not the important part).
So, I actually think that you'll have to use your own `UsereType` and I'd recommend to use the Flexible solution - working version from the Java 5 EnumUserType (see Appfuse's Java 5 Enums Persistence with Hibernate for an example).
Personally, I'd just forget the idea to use MySQL enum, I'm not convinced that the "benefits" are worth it (see this answer for more details).
Problem
In my MySQL database, there's the column "gender enum('male','female')" I've created my enum "com.mydomain.myapp.enums.Gender", and in my `Person` entity I'm defined "Gender gender". Now I'd want to keep the enum type in my MySQL database, but when I launch my application I get: Wrong column type in MyApp.Person for column Gender. Found: enum, expected: integer Why is this? This would be the equivalent as if I'd annotated my "Gender gender" with "@Enumerated(EnumType.ORDINAL)", which I haven't. EnumType seems only to be able to be either ORDINAL or STRING, so how do I specify that it should treat the field as an enum, not as an int? (not that there's much difference, but enough for it to get upset about it.)
