这段代码：

@Override
public List<FactCodeDto> getAllFactsWithoutParentsAsFactDto() {
    String completeQuery = FactCodeQueries.SELECT_DTO_FROM_FACT_WITH_NO_PARENTS;
    Query query = createHibernateQueryForUnmappedTypeFactDto(completeQuery);

    List<FactCodeDto> factDtoList = query.list(); //line 133
    return factDtoList;
}

调用此方法：

private Query createHibernateQueryForUnmappedTypeFactDto(String sqlQuery) throws HibernateException {
    return FactCodeQueries.addScalars(createSQLQuery(sqlQuery)).setResultTransformer(Transformers.aliasToBean(FactCodeDto.class));
}

给我一个ClassCastException->跟踪的一部分：

这很奇怪，因为，实际上，如果您查找Hibernate的源代码，它将尝试执行以下操作：

@Override
@SuppressWarnings("unchecked")
public void set(Object target, Object value, SessionFactoryImplementor factory) {
    ( (Map) target ).put( propertyName, value ); //line 102
}

这没有任何意义…

目标的类型为Class，此代码尝试将其强制转换为Map，

为什么要尝试这样做？？？

任何指针都值得欢迎…

我正在使用Hibernate 5（并且正在从3升级）…

编辑：我也使用Spring（4.2.1.RELEASE；也进行升级），它在部署时调用这些方法，任何调试指针也都非常受欢迎…

编辑2 ：（根据要求，整个FactCodeDto类）
