以上代码应该可行,但是我用的时候包异常,好像是连接的问题,有知道原因的大神请指点一下.
String sql = "SELECT * FROM " + tableName;/* + " WHERE Recid=" + queryParameters*/
List<Map<String, Object>> list = getSession().createSQLQuery(sql).setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP).list();
System.out.println("获取到的数据list:" +list);
这三行代码可以输出list集合,key是字段名称,value是值 <正好是我想要的>
/*String sql = "SELECT * FROM " + tableName;
List list = getSession().createSQLQuery(sql).list();
for (int i = 0; i < list.size(); i++) {
//这里要用Object[]接收查出来的list中每一条数据
Object[] obj = (Object[]) list.get(i);
System.out.println("获取到的数据:13" + Arrays.toString(obj));
}*/
如果只是查询数据的话,以上几行代码即可.
