错误 java.lang.IllegalArgumentException: org.hibernate.hql.ast.QuerySyntaxException: Utilisateurt 未映射 [从 Utilisateurt 中选择 t]

Question

Can anybody help me out of this situation?

This give an error:

Answer 1

it seems like the answer is right there - one of your queries does select t from utilisateurt , so your type.getSimpleName() seems to return utilisateurt with t at the end and I am guessing your table is called differently
