Question

hibernate用Session查询时报java.lang.String cannot be cast to java.util.Map异常

报错代码如下：Iterator tbSIt = s.createQuery("SELECT t.strName,tt.strName AS strCurName,ts.isVisible FROM pl_viewModelToolbarStatus ts LEFT JOIN ts.uidToolbar t LEFT JOIN ts.uidCurToolbar tt WHERE ts.uidViewModel=?").setParameter(0, uidViewModel).iterate();
详细错误如下：

Answer 1

类型错误，String不能转换成map类型，看看配置文件，是不是类型写错了

Answer 2

字面意思是string类型不能转换为map类型，没到你源码和报错的地方，所以不好回答啊
