2.创建applicationContext.xml文件

 <?xml version="1.0" encoding="UTF-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:context="http://www.springframework.org/schema/context"

                 <!--hibernate.xxxxxx必须以hibernate-->
                 <prop key="hibernate.show_sql">true</prop>
                 <prop key="hibernate.format_sql">true</prop>

         </property>-->
     </bean>

     <!--3.dao-->

 </beans>

3.搭建分层

4.创建实体类Dept

 /**
  * Created by Administrator on 2017/12/24.
  * 部门表
  */
 public class Dept {
     private Integer deptno;  //部门编号
     private String dname;  //部门名称
     private String loc;   //部门位置
}

5.创建映射文件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">
     <!--实体 name=实体端内容  column=DB端内容-->
     <class name="Dept" table="DEPT" dynamic-update="true">
         <!--底层数据表对应的主键-->
         <id name="deptno" column="DEPTNO">
             <!--主键生成策略： assigned  程序员手动给值-->
             <generator class="native"/>
         </id>
         <property name="dname" column="DNAME"></property>
         <property name="loc" column="LOC"></property>
     </class>

 </hibernate-mapping>

6.dao层

IDeptDAO

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

DeptDAOImpl：

 public class DeptDAOImpl implements IDeptDAO{
     private SessionFactory sessionFactory;
     public int addDept(Dept dept) {
         Serializable count = sessionFactory.getCurrentSession().save(dept);
         return (Integer)count;
     }

     public SessionFactory getSessionFactory() {
         return sessionFactory;
     }

     public void setSessionFactory(SessionFactory sessionFactory) {
         this.sessionFactory = sessionFactory;
     }
 }

service层

IDeptService

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

DeptServiceImpl

 public class DeptServiceImpl implements IDeptService {
     private IDeptDAO dao;
     @Transactional
     public int addDept(Dept dept) {
         return dao.addDept(dept);
     }

     public IDeptDAO getDao() {
         return dao;
     }

     public void setDao(IDeptDAO dao) {
         this.dao = dao;
     }
 }

Controller层

DeptController：

 @Controller
 public class DeptController {

     private IDeptService deptService;
     @RequestMapping("/adddept")
         public String addDept(Dept dept){
         deptService.addDept(dept);
         return "success";
     }
 }

add.jsp

执行后sql语句：
