使用org.hibernate.Query查询堆栈溢出，但是使用org.hibernate.Criteria查询却正常
查询如下：
public List queryStudentByClass(String classNum) {
Criteria criteria = getSession().createCriteria(Student.class);
return criteria.list();
}
public List queryStudentByClass(String classNum) {
StringBuffer hql = new StringBuffer();
hql.append(" from ");
hql.append(Student.class.getName());
Query query = this.getSession().createQuery(hql.toString());
return query.list();
}
如果使用第一个方法查询可以查到结果
但是使用第二个方法查询就会
type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception
