二.配置Web.xml

"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<display-name>Archetype Created Web Application</display-name>
<!--
Spring配置

.上下文 识别applicationContext.xml

<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!--Struts2配置 核心过滤器 -->

<!--2.监听器 在Tomcat容器启动的时候，帮我创建Spring容器，并且放入application中-->
<listener>

</web-app>
三.spring核心配置文件

xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"

">
<context:component-scan base-
package="cn.wy"></context:component-scan>
<!--

.数据源 c3p0
-->
<bean id="dataSource"
class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>

四.书写entity层和dao层
@Entity
//表示该类为实体类
@Table(name = "Student")
//表示数据库底层对应的表名
public class Student {
@Id
@GeneratedValue //orcl的主键生成策略
private Integer id;
@Column
private String name;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id =
id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name =
name;
}
}
@Repository("StudentDAO")
//将该类声明成dao
public class StudentDAOImpl
implements IStudentDAO {
@Resource(name = "sessionFactory")
//将配置文件中注册的sessionFactory注入
SessionFactory sessionFactory;
public int add(Student student) {
Session session =
sessionFactory.getCurrentSession();
Serializable save =
session.save(student);
return (Integer)save;
}
}
五.Service层
@Service("StudentService")
//将该类注册成service服务
public class StudentServiceImpl
implements IStudentService {
@Resource(name = "StudentDAO")
//将到层注入
private IStudentDAO dao;
@Transactional
public int add(Student student) {
return dao.add(student);
}
public IStudentDAO getDao() {
return dao;
}
public void setDao(IStudentDAO dao) {
this.dao =
dao;
}
}
六.action层
@Controller
//将该类声明成控制器
@ParentPackage("struts-default")
//表示status2的配置继承的是struts-default.xml
@Namespace("/")
//命名空间
@Scope("prototype")
//将spring管理该类改为多例的
public class StudentAction
implements Action {
private Student student;
@Resource(name = "StudentService")
//将Service注入
private IStudentService studentService;
// 请求路劲 请求成功 跳转的页面
@org.apache.struts2.convention.annotation.Action(value = "/add",results = {@Result(name = "success",location = "/jsp/index.jsp"
)})
public String execute()
throws Exception {
studentService.add(student);
return SUCCESS;
}
public Student getStudent() {
return student;
}
public void setStudent(Student student) {
this.student =
student;
}
public IStudentService getStudentService() {
return studentService;
}
public void setStudentService(IStudentService studentService) {
this.studentService =
studentService;
}
}
