1、hibernate 5.2 之后，SQLQuery.class、setResultTransformer方法已作废，其用法如下:

Query query = entityManager.createNativeQuery(sql, clazz);query.unwrap(SQLQuery.class).setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP);

替换后为：

Query query = entityManager.createNativeQuery(sql, clazz);  query.unwrap(NativeQueryImpl.class).setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP);
