查数据:
public List<CibDeptView> queryCibDept() {
final Criteria criteria = this.getSession().createCriteria(CibDeptView.class);
return criteria.list();
}
获取方法:
private List<CibDeptView> CibDeptList;
public List<CibDeptView> queryDeptList(){
CibDeptList = this.cibDeptDao.queryDeptList();
return CibDeptList;
}
jsp显示:
<select name="dept">
<option value="" selected="true">请选择处室</option>
<%
QueryCibDept cibDept = new QueryCibDept();
List<CibDeptView> list = cibDept.queryDeptList();
for(CibDeptView li:list){
%>
<option value="<%=li.getDept()%>"><%=li.getDept()%></option><%}%>
</select>
请问有什么问题吗?
List<CibDeptView> list = cibDept.queryDeptList();这一行报错
