下面就举SSH的例子来进行详细的説明:
登陆的Action:
1.控制层
(1).LoginAction:
只需要导入登陆的ILoginService接口
eg:
ILoginService loginService;
private Admin admin = null;
public String adminLogin() {
Admin _admin = loginService.adminLogin(admin.getAdminAccount(), admin
.getPassword());
HttpServletRequest request = ServletActionContext.getRequest();
HttpSession session = request.getSession();
if (_admin != null) {
session.removeAttribute("adminObj");
session.setAttribute("adminObj", _admin);
return SUCCESS;
} else {
return FLASE;
}
}
2.业务逻辑层
(1).登陆接口ILoginService的详细代码:
eg:
public interface ILoginService {
Admin adminLogin(String adminAccount, String password);
}
(2).登陆LoginService的详细代码:
eg:
public class LoginService implements ILoginService{
ILoginDao loginDao;
public ILoginDao getLoginDao() {
return loginDao;
}
public void setLoginDao(ILoginDao loginDao) {
this.loginDao = loginDao;
}
public Admin adminLogin(String adminAccount, String password) {
return loginDao.adminLogin(adminAccount, password);
}
}
3.数据访问层:
(1)登陆接口ILoginDao
eg:
public interface ILoginDao {
Admin adminLogin(String adminAccount, String password);
}
(2)登陆DAO-loginDao
public class LoginDao extends HibernateDaoSupport implements ILoginDao{
public Admin adminLogin(String adminAccount, String password) {
String hql = "from Admin as admin where admin.adminAccount='"
+ adminAccount + "' and admin.password='" + password + "'";
List list = this.getHibernateTemplate().find(hql);
return (list.size() != 0) ? ((Admin) list.get(0)) : null;
}
}
4.Spring配置文件
(1)(登陆的配置文件)-applicationContext_login.xml
eg:
(2)总的Spring配置文件
classpath:com/itanger/domain/
org.hibernate.dialect.MySQLDialect
true

以上的学习,你基本上对面向借口编程和SSH有了一点的了解,其中面向接口编程为什么好,为什么适用了面向接口后,对以后的维护有帮助,对代码的修改有帮助,这个你就在日常的工作中慢慢的体会吧,多说不益。。。。
