Spring，SpringMVC和hibernate整合小demo

DeptController

@Controllerpublic class DeptController {    //植入service    @Resource    private IDeptService deptService;    @RequestMapping("/addDept")   public String add(Dept dept){         deptService.addDept(dept);         return "index";   }}

IDeptDAO

public interface IDeptDAO {    //添加部门的方法    public int addDept(Dept dept, Session session);}

DeptDAOImpl

public class DeptDAOImpl implements IDeptDAO{    public int addDept(Dept dept,Session session) {        Serializable count = session.save(dept);        return (Integer) count;    }}

Dept持久类

public class Dept {    private Integer deptno;    private String deptname;    public Integer getDeptno() {        return deptno;    }    public void setDeptno(Integer deptno) {        this.deptno = deptno;    }    public String getDeptname() {        return deptname;    }    public void setDeptname(String deptname) {        this.deptname = deptname;    }}

Dept.hbm.xml

<?xml version="1.0"?><!DOCTYPE hibernate-mapping PUBLIC        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"><hibernate-mapping package="cn.happy.entity">    <class name="Dept" table="Dept">        <id name="deptno" column="deptno">            <generator class="native"></generator>        </id>        <property name="deptname" />    </class></hibernate-mapping>

IDeptService

public interface IDeptService {    public int addDept(Dept dept);}

DeptServiceImpl

public interface IDeptService {    public int addDept(Dept dept);}

HibernateUtil工具类

public class HibernateUtil {    private static ThreadLocal<Session> tl;    private static Configuration cfg;    private static SessionFactory factory;    static {        tl=new ThreadLocal<Session>();        cfg=new Configuration().configure();        factory=cfg.buildSessionFactory();    }    //获取和当前线程绑定的session    public static Session getSession(){        //尝试着从线程中看看有没有线程变量        Session session = tl.get();        if (session==null){            //线程中没有session对象，创建一个            session = factory.openSession();            tl.set(session);        }        return session; //没有和当前线程绑定    }    public static void closeSession(){        Session session = tl.get();        tl.set(null);        session.close();    }}
