Question

Type definition error: [simple type, class org.hibernate.proxy.pojo.bytebuddy.ByteBuddy

Answer 1

I came across this error while doing a tutorial with spring repository. It turned out that the error was made at the stage of building the service class for my entity.

In your serviceImpl class, you probably have something like:

    @Override
    public YourEntityClass findYourEntityClassById(Long id) {
      return YourEntityClassRepositorie.getOne(id);
    }

Change this to:

    @Override
    public YourEntityClass findYourEntityClassById(Long id) {
      return YourEntityClassRepositorie.findById(id).get();
    }

It's because the getOne(), returns a reference.
