Question

我正在尝试使用spring hibernate将一些记录插入到我的数据库表中，但是在运行project之后会出现以下错误。请帮助我解决问题..谢谢

实体类Admin.java

AdminServiceImpl.java类

package com.finalproject.service.impl;

import com.finalproject.dao.AdminDao;
import com.finalproject.entity.Admin;
import com.finalproject.service.AdminService;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;


@Service("adminService")
@Transactional(propagation = Propagation.SUPPORTS,rollbackFor = Exception.class)
public class AdminServiceImpl implements AdminService {

    @Autowired
    AdminDao adminDao;

    @Override
    public void create(Admin admin) {
        adminDao.create(admin);
    }

    @Override
    public void update(Admin admin) {
        adminDao.update(admin);
    }

    @Override
    public void delete(Long adminId) {
        adminDao.delete(adminId);
    }

    @Override
    public Admin edit(Long adminId) {
        return adminDao.edit(adminId);
    }

    @Override
    public List<Admin> getAll() {
        return adminDao.getAll();
    }

    @Override
    public Admin find(Long adminId) {
        return adminDao.find(adminId);
    }

}

Dao实现了类AdminDaoImpl.java

package com.finalproject.dao.impl;

import com.finalproject.dao.AdminDao;
import com.finalproject.entity.Admin;
import java.util.List;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

@Repository("adminDao")
public class AdminDaoImpl implements AdminDao {

    @Autowired
    SessionFactory sessionFactory;
    

    protected Session currentSession() {
        return sessionFactory.getCurrentSession();
    }

    @Override
    public void create(Admin admin) {
        currentSession().save(admin);
    }

    @Override
    public void update(Admin admin) {
        currentSession().update(admin);
    }

    @Override
    public void delete(Long adminId) {
        currentSession().delete(adminId);
    }

    @Override
    public Admin edit(Long adminId) {
        return find(adminId);
    }

    @Override
    public Admin find(Long adminId) {
        return (Admin) currentSession().get(Admin.class, adminId);
    }

    @Override
    public List<Admin> getAll() {
        return currentSession().createCriteria(Admin.class).list();
    }

}

控制器类AdminController.java

package com.finalproject.controller;

import com.finalproject.entity.Admin;
import com.finalproject.service.AdminService;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping(value = "/admin")
public class AdminController {

    @Autowired
    AdminService adminService;

    @RequestMapping(value = "/register", method = RequestMethod.GET)
    public String register(Map<String, Object> map) {
        map.put("adminReg", new Admin());
        return "/admin/add";
    }

    @RequestMapping(value = "/create", method = RequestMethod.POST)
    public String create(Admin admin, Map<String, Object> map) {
        adminService.create(admin);
        return "redirect:/admin/details/" + admin.getAdminId();
    }

    @RequestMapping(value = "/details/{adminId}",method = RequestMethod.GET)
    public String details(@PathVariable("adminId") Long adminId, Map<String, Object> map) {
        Admin admin = adminService.find(adminId);
        map.put("adminName", admin.getAdminName());
        map.put("adminEmail", admin.getAdminEmail());
        map.put("adminPass", admin.getAdminPass());

        return "admin/details";
    }

}
