hibernate版本: hibernate-core-5.3.21.Final遇到的问题是这样的:Spring Data JPA集成hibernate, 定义的JpaRepository接口方法:@Query(value = "select * from xxx", nativeQuery=true)List<Map<String, Object>> queryXXXX();数据库是mysql, 其中一个字段类型为smallint unsigned.该字段可以存储0--65535, 而hibernate执行查询, 对结果进行转化时, 自动进行类型判断, 将该字段中的值存入了Short里, 导致装不下, 最终报错:Caused by: org.hibernate.exception.DataException: could not execute query at
