mysql - HTTP 状态 500 - 请求处理失败；嵌套异常是 org.hibernate.exception.ConstraintViolationException : could not execute update query

标签 mysql spring jsp spring-mvc hibernate-annotations

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。

HTTP Status 500 - Request processing failed; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute update query`

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());
         model.put("teamKey", teamservice.listTeams());
         return new ModelAndView("Device",model);
        }

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。

com.mysql.jdbc.exceptions.MySQLIntegrityConstraintViolationException: ...
    ...
    com.resource.ResourceDao.DeviceDaoImpl.deleteDevice(DeviceDaoImpl.java:39)
    ...

关于mysql - HTTP 状态 500 - 请求处理失败；嵌套异常是 org.hibernate.exception.ConstraintViolationException : could not execute update query，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24525714/
