部署应用程序后出现错误。我已经检查了类似的问题，但仍然无法解决该错误。我已经将@Transactional用于服务类以及

    org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here

我有以下项目文件： 控制器：

    @Controller
public class CustomerController {
    @Autowired
    private CustomerManager customerManager;

    @RequestMapping(value="/", method= RequestMethod.GET)
    public String listCustomers(ModelMap map){
        map.addAttribute("customer", new Customer());
        map.addAttribute("customerList", customerManager.getAllCustomer());
        return "CustomerList";
    }

    @RequestMapping(value = "/add", method = RequestMethod.POST)
    public String addCustomer(@ModelAttribute(value="customer") Customer customer, BindingResult result)
    {
        customerManager.addCustomer(customer);
        return "redirect:/";
    }
    @RequestMapping("/delete/{customerId}")
    public String deleteEmplyee(@PathVariable("customerId") Integer customerId)
    {
        customerManager.deleteCustomer(customerId);
        return "redirect:/";
    }

    public void setCustomerManager(CustomerManager customerManager) {
        this.customerManager = customerManager;
    }
}

道课

public class CustomerDaoImpl implements CustomerDao{
    @Autowired

    private SessionFactory sessionFactory;

    public void addCustomer(Customer customer) {
        this.sessionFactory.getCurrentSession().save(customer);
    }

    @SuppressWarnings("unchecked")
    public List<Customer> getAllCustomer() {
        return this.sessionFactory.getCurrentSession().createQuery("from Customer").list();
    }

    public void deleteCustomer(Integer customerId) {
        Customer customer = (Customer) sessionFactory.getCurrentSession().load(Customer.class, customerId);
        if (null != customer) {
            this.sessionFactory.getCurrentSession().delete(customer);
        }
    }

}

Dto：

@Entity
@Table(name="Customer")
public class Customer {
    @Id
    @Column(name="ID")
    @GeneratedValue
    private int id;

   @Column(name="NAME")
   private String name;

    @Column(name="CONTACT")
    private String contact;

    @Column(name="EMAIL")
    private String email;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getContact() {
        return contact;
    }

    public void setContact(String contact) {
        this.contact = contact;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }
}

Manager类的实现

    package com.utd.service;

import com.utd.dao.CustomerDao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.utd.dto.Customer;

import javax.transaction.Transactional;
import java.util.List;

@Service
public class CustomerManagerImpl implements CustomerManager {
    @Autowired
    private CustomerDao customerDao;

    @Transactional
    public void addCustomer(Customer customer) {
        customerDao.addCustomer(customer);
    }

    @Transactional
    public List<Customer> getAllCustomer() {
        return customerDao.getAllCustomer();
    }

    @Transactional
    public void deleteCustomer(Integer customerId) {
        customerDao.deleteCustomer(customerId);
    }

    public void setCustomerDao(CustomerDao customerDao) {
        this.customerDao = customerDao;
    }
}

我想知道如何解决该错误。
