[英]Spring Hibernate: No Dialect mapping for JDBC type: -101
I'm working on a spring-boot app and trying to build my repository, and am having an issue with Hibernate. 我正在开发一个春季启动应用程序,并试图构建我的存储库,并且Hibernate遇到了问题。

Repository: 库:
//@Repository
//public interface PWeightTagsRepository extends JpaRepository<PTags, Integer>{
//
// @Query(value = "SELECT T FROM PTags T WHERE T.adbLDeliveryStatus = 'N' ORDER BY T.adbSequence ASC")
// List<PTags> getNewMessages();
//}
@Repository
public class PWeightTagsRepository{
@Autowired
protected EntityManager em;
public List<PTags> getNewMessages(Integer limit){
javax.persistence.Query query = em.createNativeQuery("SELECT T.* FROM GSTARTIB.P_TAGS T WHERE T.ADB_L_DELIVERY_STATUS = 'N'");
return query.getResultList();
}
}
My confusion is that, if I uncomment the first function in the repository, it will run and return results without any problem. 我的困惑是,如果我取消注释存储库中的第一个函数,它将运行并返回结果而没有任何问题。
But, when running the second function, I get: org.hibernate.MappingException: No Dialect mapping for JDBC type: -101
error even though in my application.properties file I have a dialect declared. 但是,当运行第二个函数时,我得到:
org.hibernate.MappingException: No Dialect mapping for JDBC type: -101
错误,即使在我的application.properties文件中我声明了一种方言。
What am I missing here? 我在这里想念什么?
Well, I found the problem. 好吧,我发现了问题。
The error message it gives seems misleading to me, as it doesn't match what the solution is. 它给出的错误消息似乎使我误解,因为它与解决方案不匹配。
I needed to provide the createNativeQuery
function with a .class
to cast the results too. 我还需要为
createNativeQuery
函数提供一个.class
来转换结果。
em.createNativeQuery(<query>, PTags.class)
fixed the issue em.createNativeQuery(<query>, PTags.class)
