Question

 List<Candidate> candidates = (List<Candidate>) session.createSQLQuery("select candidate.* from candidate inner join candidate_skill on candidate.id = candidate_skill.candidate_id inner join skill on candidate_skill.skill_id = skill.id where skill.id = 1");

我明白了：

 java.lang.ClassCastException: org.hibernate.internal.SQLQueryImpl cannot be cast to java.util.List

查询是正确的。如何解决？

Answer 1

您在查询结束时忘记了.list()。

应该是

................skill.id where skill.id = 1").list();

有关详细信息，请参阅hibernate documentation。

Answer 2

查询不返回任何内容，并且您尝试将其分配给列表

你应该做

 List<Candidate> candidates = (List<Candidate>) session.createSQLQuery
               ("select candidate.* from candidate inner join 
                    candidate_skill on candidate.id = candidate_skill.
                        candidate_id inner join skill on 
                  candidate_skill.skill_id = skill.id 
                                          where skill.id = 1").list();
