我正在尝试在这里注册一个新员工。问题是这些值没有被插入到数据库中。虽然 save() 保存值的工作对吗？我在这里附上我的代码。

package net.admin.module.controller;
import java.util.List;


import org.hibernate.HibernateException;
import org.hibernate.Query;
import org.hibernate.Transaction;
import org.hibernate.classic.Session;





import net.admin.module.model.Employee;
import net.admin.module.util.HibernateUtil;

public class EmployeeManager extends HibernateUtil {

    public Employee add(Employee employee) {
        Session session = HibernateUtil.getSessionFactory().getCurrentSession();
        session.beginTransaction();
        session.save(employee);
        session.getTransaction().commit();
        return employee;
    }
    public Employee delete(int id) {
        Session session = HibernateUtil.getSessionFactory().getCurrentSession();
        session.beginTransaction();
        Employee employee = (Employee) session.load(Employee.class, id);
        if(null != employee) {
            session.delete(employee);
        }
        session.getTransaction().commit();
        return employee;
    }


        public List<Employee> list() {

        Session session = HibernateUtil.getSessionFactory().getCurrentSession();
        session.beginTransaction();
        List<Employee> employee = null;
        try {

            employee = (List<Employee>)session.createQuery("from Employee").list();

        } catch (HibernateException e) {
            e.printStackTrace();
            session.getTransaction().rollback();
        }
        session.getTransaction().commit();
        return employee;
    }
    }

这是我的 EmployeeManager.java 类。它是我的控制器。

package net.admin.module.view;

import java.util.List;
import net.admin.module.controller.EmployeeManager;
import net.admin.module.model.Employee;
import com.opensymphony.xwork2.ActionSupport;

public class EmployeeAction extends ActionSupport {

    private static final long serialVersionUID = 9149826260758390091L;
    private Employee employee;
    private List<Employee> employeeList;
    private int id;

    private EmployeeManager employeeManager;

    public EmployeeAction() {
        employeeManager = new EmployeeManager();
    }

    public String execute() {
        this.employeeList = employeeManager.list();
        System.out.println("execute called");
        return SUCCESS;
    }



    public String add() {
        System.out.println(getEmployee());
        try {
            employeeManager.add(getEmployee());
        } catch (Exception e) {
            e.printStackTrace();
        }
        this.employeeList = employeeManager.list();
        return SUCCESS;
    }


    public String delete() {
        employeeManager.delete(getId());
        return SUCCESS;
    }

    public Employee getEmployee() {
        return employee;
    }

    public List<Employee> getEmployeeList() {
        return employeeList;
    }

    public void setEmployee(Employee employee) {
        this.employee = employee;
    }

    public void setEmployeeList(List<Employee> employeeList) {
        this.employeeList = employeeList;
    }

    public int getId() {
        return id;
    }

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

这是我的 EmployeeAction.java 类。这是我的行动课。

这是我的 jsp - index.jsp 。我在这里转发。我可以在 jsp 页面中看到插入的值，但它没有插入到数据库中。
