- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
您好,在我的 spring mvc hibernate 注释应用程序中,我有 3 个表Employee、Team、Platform。我正在使用下拉框进行选择Platform.jsp 和 Employee.jsp 中的团队名称。当我尝试删除团队而不从员工表和平台表中删除相应引用的引用时,出现以下错误。

这是 ResourceDaoImpl.java 中使用的查询
@Override
public void deleteResource(int resourceid) {
// TODO Auto-generated method stub
sessionfactory.getCurrentSession().createQuery("DELETE FROM Resource WHERE empid=" +resourceid).executeUpdate();
}
在AddTeamDaoImpl.java中用于删除的查询
@Override
public void deleteTeams(int teamid) {
// TODO Auto-generated method stub
sessiofactory.getCurrentSession().createQuery("DELETE FROM AddTeam WHERE teamid="+teamid).executeUpdate();
}
用于删除DeviceDaoImpl.java的查询
@Override
public void deleteDevice(int deviceid) {
// TODO Auto-generated method stub
sessionfactory.getCurrentSession().createQuery("DELETE FROM AddTeam WHERE teamid="+deviceid).executeUpdate();
}
ResourceController.java 中的删除函数
@RequestMapping(value="/delete",method=RequestMethod.GET)
public ModelAndView deleteResourceDetails(@ModelAttribute("command") Resource resource,
BindingResult result){
resourceServices.deleteResource(resource.getEmpId());
Map<String, Object> model = new HashMap<String, Object>();
model.put("resourcekey", resourceServices.listResources());
model.put("teamKey", addteamServices.listTeams());
return new ModelAndView("EditTeam",model);
}
DeviceController.java 中的删除函数
@RequestMapping(value="/deletePlatform", method = RequestMethod.GET)
public ModelAndView deleteDevice(@ModelAttribute("command") Device device, BindingResult result){
deviceService.deleteDevice(device.getpId());
Map<String, Object> model = new HashMap<String, Object>();
model.put("platformKey", deviceService.listDevice());

请帮忙提前谢谢
最佳答案
您在 DeviceDaoImpl
中的查询看起来有误:
"DELETE FROM AddTeam WHERE teamid="+deviceid
一般性提示:您发布的堆栈跟踪可以直接将您引导至问题。
