</beans>

5.person对象和Person.hbm.xml文件(pojo对象与数据库中的表一一对应)
Person.class

package per.czt.springmvc.domain;
public class Person {
    private Integer id;
    private String name;
    private Integer age;
    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;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
}

Person.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!-- 映射文件需要dtd指定格式 -->
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="per.czt.springmvc.domain">
    <class name="Person" lazy="true" table="person">
        <id name="id" column="id" type="java.lang.Integer">
            <generator class="identity"></generator>
        </id>
        <property name="name" type="java.lang.String">
            <column name="name" />
        </property>
        <property name="age" type="java.lang.Integer">
            <column name="age" />
        </property>
    </class>
</hibernate-mapping>

6.dao层：定义一个接口，然后实现接口，获取sessionFactory(在bean.xml配置bean)实现对数据库的操作
PersonDao

package per.czt.springmvc.dao;
import java.util.List;
import per.czt.springmvc.domain.Person;
public interface PersonDao {
    public List<Person> listAll(String hql);
    public Person getById(Integer id);
    public void saveOrUpdate(Person p);
    public void deleteById(Integer id);
}

PersonDaoImpl

package per.czt.springmvc.dao;
import java.util.List;
import javax.annotation.Resource;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import per.czt.springmvc.domain.Person;
@Repository("personDao")
public class PersonDaoImpl  implements PersonDao {
    private SessionFactory sessionFactory;
    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }
    @Override
    public List<Person> listAll(String hql) {
        System.out.println("sessionFactory:"+sessionFactory);
        System.out.println("hql:"+hql);
        System.out.println(" sessionFactory.getCurrentSession():"+ sessionFactory.getCurrentSession());
        List<Person> personList=(List<Person>) sessionFactory.getCurrentSession().createQuery(hql).list();
        System.out.println("personList:"+personList.size());
        return personList;
    }
    @Override
    public Person getById(Integer id) {
        return (Person)sessionFactory.getCurrentSession().get(Person.class, id);
    }
    @Override
    public void saveOrUpdate(Person p) {
        sessionFactory.getCurrentSession().saveOrUpdate(p);
    }
    @Override
    public void deleteById(Integer id) {
        sessionFactory.getCurrentSession().delete(this.getById(id));
    }
}

7.servic层:对dao层的结果处理，这里也是接口调用
PersonService

package per.czt.springmvc.service;
import java.util.List;
import per.czt.springmvc.domain.Person;
public interface PersonService {
    public List<Person> listAll(String hql);
    public Person getById(Integer id);
    public void saveOrUpdate(Person p);
    public void deleteById(Integer id);
}

PersonServiceImpl

package per.czt.springmvc.service;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import per.czt.springmvc.dao.PersonDao;
import per.czt.springmvc.dao.PersonDaoImpl;
import per.czt.springmvc.domain.Person;
@Service("personService")
public class PersonServiceImpl implements PersonService {
    @Resource(name="personDao")
    private PersonDao personDao;
    public PersonDao getPersonDao() {
        return personDao;
    }
    public void setPersonDao(PersonDao personDao) {
        this.personDao = personDao;
    }
    @Override
    public List<Person> listAll(String hql) {
        System.out.println("personDao:"+personDao);
        return personDao.listAll(hql);
    }
    @Override
    public Person getById(Integer id) {
        // TODO Auto-generated method stub
        return personDao.getById(id);
    }
    @Override
    public void saveOrUpdate(Person p) {
        personDao.saveOrUpdate(p);
    }
    @Override
    public void deleteById(Integer id) {
        personDao.deleteById(id);
    }
}

8.controller层:调用service，并且将结果显示到view层，即jsp页面
PersonController

package per.czt.springmvc.web.controller;
import java.util.List;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import per.czt.springmvc.domain.Person;
import per.czt.springmvc.service.PersonService;
@Controller
@RequestMapping("/person")
public class PersonController {
    private PersonService personService;
    @RequestMapping("/listAll")
    public String listAll(Model model)
    {
        ApplicationContext ac=new ClassPathXmlApplicationContext("beans.xml");
        personService=(PersonService) ac.getBean("personService");
        System.out.println("personService1:"+personService);
        System.out.println("personService:"+personService);
        List<Person> personList=personService.listAll("from Person");
        System.out.println("personList.size()"+personList);
        model.addAttribute(personList);
        return "person/personList";
    }
}

9.view层:显示controller层返回的结果
person.jsp(在WEB-INF/person下)

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
    <table>
        <tbody>
            <tr>
                <th>id</th>
                <th>name</th>
                <th>age</th>
            </tr>
            <c:forEach items="${personList }" var="person">
                <tr>
                    <td>${person.id }</td>
                    <td>${person.name }</td>
                    <td>${person.age }</td>
                </tr>
            </c:forEach>
        </tbody>
    </table>
</body>
</html>

index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
    <a href="${pageContext.request.contextPath }/person/listAll.action">显示列表</a>
</body>
</html>

10.在index.jsp点击显示列表，即可显示所有person了
