Question

我的查询在oracle中运行但在我的java代码中选择wuery会抛出无效的列名。我的实体：

@Basic
@Column(name = "kasr_uni", columnDefinition = "VARCHAR2(100)")
private String kasr_uni;

我的查询类：

@Repository
@Transactional
public class ExportManagerImpl implements ExportManager {
@PersistenceContext
private EntityManager entityManager;

    @Override
    public List getAllUnis() {
        return entityManager.createNativeQuery("SELECT kasr_uni FROM KASR GROUP BY kasr_uni ORDER BY kasr_uni ASC",Kasr.class).getResultList();
    }
}

异常：

  java.sql.SQLException: Invalid column name
oracle.jdbc.driver.OracleStatement.getColumnIndex(OracleStatement.java:3757)
oracle.jdbc.driver.InsensitiveScrollableResultSet.findColumn(InsensitiveScrollableResultSet.java:264)

为什么Hibernate会引发无效的列名异常？
