1、结构
2、控制器

import javax.servlet.ServletContext;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;

/*
* @Controller
* 控制器
*
* @Service
* 用于标注业务层组件
*
* @Repository
* 用于标注数据訪问组件。即DAO组件
*
* @Component
* 泛指组件，当组件不好归类的时候我们能够使用这个注解进行标注，（如今能够都用此注解）
* 同上事实上跟@Service/@Repository/@Controller 一样仅仅只是它们 利用分层 好区分
*
* @Autowired@Resource
* 自己主动注入 实现的的是 setXxx()方法 getXxx()方法
*
* @RequestMapping(value='xxx.do',method=RequestMethod.GET/RequestMethod.POST/..)
* value訪问路径/method请发的方法，注：请求方法一旦设定仅仅能使用指定的方法訪问
* 在类前面定义，则将url和类绑定。
* 在方法前面定义，则将url和类的方法绑定
*
* @RequestParam("name") ==uname
* 一般用于将指定的请求參数付给方法中形參
*
* @Scope
* 创建 bean的作用域 singleton-->多例 Property-->多例 还有request 等等
* 使用reqeust 须要在web.xml 配置监听器 详细去网上搜索
*
*/

/*ModelAndView 与 ModelMap 的差别
*
* ModelAndView
* 作用一 ：设置转向地址/对象必须手动创建（主要差别）
*
* 作用二：用于传递控制方法处理结果数据到结果页面，
* 也就是说我们把须要在结果页面上须要的数
* 据放到ModelAndView对象中就可以，他
* 的作用相似于request对象的setAttr
* ibute方法的作用，用来在一个请求过程中
* 传递处理的数据。通过下面方法向页面传递 參数：addObject(String key,Object value);
*
*
* ModelMap
*一、 ModelMap的实例是由bboss mvc框架自己主动创建并作为控制器方法參数传入。
* 用户无需自己创建。
*
* 二、ModelMap对象主要用于传递控制方法处理数据到结果页面，也就是说我们把结果页面上须要的数据放到ModelMap对象中就可以，
* 他的作用相似于request对象的setAttribute方法的作用。用来在一个请求过程中传递处理的数据。
通过下面方法向页面传递參数：
* addAttribute(String key,Object value);
* 在页面上能够通过el变量方式$key或者bboss的一系列数据展示标签获取并展示modelmap中的数据。
* modelmap本身不能设置页面跳转的url地址别名或者物理跳转地址，那么我们能够通过控制器方法的返回值来设置跳转url地址
* 别名或者物理跳转地址。
*/
@RequestMapping("/modelmap.do")
public String modelMapMethod(String name,ModelMap model) {
//将数据放置到ModelMap对象model中,第二个參数能够是不论什么java类型

//构建ModelAndView实例，并设置跳转地址
ModelAndView view = new ModelAndView("index");
//将数据放置到ModelAndView对象view中,第二个參数能够是不论什么java类型
view.addObject("modelAndMap",name);
//返回ModelAndView对象view
return view;
}
}
3、DAO接口
package com.ai.customer.dao;
import java.util.List;
import com.ai.customer.model.CustomerInfo;
public interface ICustomerDao {
//查询Customer
public List<CustomerInfo> queryCustomer();
public String all();
}4、DAO接口实现
package com.ai.customer.daoimpl;
import java.util.List;
import org.hibernate.Hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Repository;
import com.ai.customer.dao.ICustomerDao;
import com.ai.customer.model.CustomerInfo;
@Repository
public class CustomerDao implements ICustomerDao {
@Autowired
private SessionFactory sessionFactory;
// public void setSessionFactory(SessionFactory sessionFactory) {
// this.sessionFactory = sessionFactory;
// }
public List<CustomerInfo> queryCustomer() {
//System.out.println(sessionFactory);
//Configuration config=new Configuration().configure("config/hibernet/hibernate.cfg.xml");
//SessionFactory f=config.buildSessionFactory();
Session session=sessionFactory.openSession();
List<CustomerInfo> cus=session.createQuery("from CustomerInfo").list();
session.close();
return cus;
}
public String all(){
return "注解成功";
}
public static void main(String[] args) {
Configuration config=new Configuration().configure("config/hibernet/hibernate.cfg.xml");
SessionFactory f=config.buildSessionFactory();
Session session=f.openSession();
List<CustomerInfo> cus=session.createQuery("from CustomerInfo").list();
session.close();
System.out.println(cus.get(0).getCustomerid());
// System.out.println(f.getCurrentSession().createQuery("from CustomerInfo").list());
}
}
5、实体类
package com.ai.customer.model;
import java.io.Serializable;
public class CustomerInfo implements Serializable {
/**

private static final long serialVersionUID = 1L;
private String customerid;//个人编号
private String cardid;//身份证id

}
public String getRegTime() {
return regTime;
}
public void setRegTime(String regTime) {
