重新学习之spring第四个程序，整合struts2+hibernate+spring

第一步:导入三大框架的jar包（struts2.3.16.1+hibernate3.2+spring3.2.4）

第二步:编写web.xml 和struts.xml和applicationContext.xml和applicationContext-service.xml和application-actionContext.xml和applicationContext-dao.xml

web.xml

 <?xml version="1.0" encoding="UTF-8"?>
 <web-app version="2.5"

第三步：测试--项目布局。

项目布局

student.hbm.xml

 <?xml version="1.0"?>
 <!DOCTYPE hibernate-mapping PUBLIC
     "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
     "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
 <hibernate-mapping
     package="com.bjsxt.sxf.po"><!-- 实体类包名 -->

     <class name="Student" table="shang_student">

         <!-- 主键递增 -->
         <id name="id" column="id">
             <generator class="native"></generator>
         </id>

         <!-- 学生名字 -->
         <property name="name" column="name"></property>
         <!-- 学生性别 -->
         <property name="sex" column="sex"></property>

     </class>

 </hibernate-mapping>

添加一个用户

访问localhost:8080/Struts2HibernateSpring/StudentAction!add向数据库中的表添加一个用户

StudenAction省去setget方法

 public class StudentAction {
     private StudentService studentService;

     public String add(){
         System.out.println("StudentAction.add(8888888888888)");
         Student student =new Student();
         student.setName("shangxiaoyan");
         student.setSex("女");
         studentService.addStudent(student);
         return null;
     }
