Positional parameter are considered deprecated; use named parameters or JPA-style positional parameters instead.

这行代码：

 List<Cat> catList =session.createQuery("from Cat p where p.name.first_name=?").setParameter(0,name.getFirst_name()).list();

改为：

 String hql = "from Cat p where p.name.first_name=:name";
 Query query = session.createQuery(hql);
 query.setParameter("name", name.getFirst_name());
 List<Cat> catList = query.list();
