上篇博文中写了spring与springmvc的整合，而这一篇则是又加上了hibernate。
与上次一样，这一次仍然是先导入jar包，这一次则要加入hibernate中的jar包，如下图所示：
同时再新建两个源文件夹，一个为config，一个为test，分别存放配置文件与测试用例，现在来进行spring，springmvc以及hibernate的配置。
新建spring-hibernate.xml,applicationContext.xml,springmvc.xml,hibernate.cfg.xml四个配置文件，现在来对这四个配置文件进行配置。
spring-hibernate.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd" [

applicationContext.xml:

hibernate映射文件为：
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<session-factory>
<mapping resource="cn/com/domain/Users.hbm.xml"></mapping>
</session-factory>
</hibernate-configuration>现在在web.xml中进行配置：

</web-app>
现在开始编程过程：
User类：
package cn.com.domain;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import org.hibernate.annotations.GenericGenerator;
public class Users implements Serializable {
private String id;
private String name;
private String pwd;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
}
对应的User.hbm.xml配置文件为：
<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="cn.com.domain.Users" table="users"> <id name="id" type="java.lang.String"> <column name="id"></column> </id> <property name="name" type="java.lang.String" length="20"></property> <property name="pwd" type="java.lang.String" length="20"></property> </class> </hibernate-mapping>
IUserDao:
package cn.com.dao;
import cn.com.domain.Users;
public interface IUserDao {
public void addUser(Users user);
public void updateUser(Users user);
}
IUserDaoImpl:
package cn.com.dao.impl;
import org.springframework.orm.hibernate3.HibernateTemplate;
import cn.com.dao.IUserDao;
import cn.com.domain.Users;
public class UserDaoImpl implements IUserDao {
private HibernateTemplate hibernateTemplate;
public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
}
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
public void addUser(Users user) {
this.hibernateTemplate.save(user);
}
public void updateUser(Users user) {
this.hibernateTemplate.update(user);
}
}
IUserService:
package cn.com.service;
import cn.com.domain.Users;
public interface IUserService {
public void addUser(Users users);
public void updateUser(Users user);
}
IUserServiceImpl:
package cn.com.service.impl;
import cn.com.dao.IUserDao;
import cn.com.domain.Users;
import cn.com.service.IUserService;
public class UserServiceImpl implements IUserService {
private IUserDao userDao;
public void addUser(Users users) {
this.userDao.addUser(users);
}
public IUserDao getUserDao() {
return userDao;
}
public void setUserDao(IUserDao userDao) {
this.userDao = userDao;
}
public void updateUser(Users user) {
this.userDao.updateUser(user);
}
}
编写的一个工具类：
ServiceProvinderCore：
package cn.com.container;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
/**
* 该类的主要目的是加载spring配置文件
* @author Administrator
*
*/
public class ServiceProvinderCore {
protected ApplicationContext context;
public void load(String filename){
context=new ClassPathXmlApplicationContext(filename);
}
}
ServiceProvinder：
package cn.com.container;
import org.springframework.util.StringUtils;
public class ServiceProvinder {
private static ServiceProvinderCore sc;
static{
sc=new ServiceProvinderCore();
sc.load("applicationContext.xml");
}
public static Object getService(String beanName){
Object bean=null;
if(!StringUtils.hasText(beanName)){
throw new RuntimeException("您要访问的服务名不能为空！");
}
//如果spring容器中包含beanName
if(sc.context.containsBean(beanName)){
bean=sc.context.getBean(beanName);
}
//如果spring容器中不包含beanName
if(bean==null){
throw new RuntimeException("您要访问的服务名称["+beanName+"]不存在");
}
return bean;
}
}
控制器UserController：
package cn.com.controller;
import java.util.UUID;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import cn.com.container.ServiceProvinder;
import cn.com.dao.IUserDao;
import cn.com.domain.Users;
import cn.com.service.IUserService;
@Controller
@RequestMapping("/user")
public class UserController {
@RequestMapping("/toSuccess.do")
public String toSuccess(){
System.out.println("success");
return "success";
}
@RequestMapping("/toAdd.do")
public String add(){
return "add";
}
@RequestMapping("/toLogin.do")
public String login(){
return "login";
}
@RequestMapping("/toSave.do")
public String save(Users user){
System.out.println(user.getName());
System.out.println(user.getPwd());
String id=UUID.randomUUID().toString().replace("-", "").substring(0,4);
user.setId(id);
ServiceProvinder provinder=new ServiceProvinder();
IUserService userDao=(IUserService) provinder.getService("userService");
userDao.addUser(user);
return "success";
}
}
在这些包以及各个类的编写中，总体结构为：
现在来进行测试：
add.jsp
点击提交以后：
jsp页面转向为：
成功完成整合。
在这里使用的是xml配置的文件来进行开发，如果是使用注解来做的话会更为简单一些。
spring+springmvc+hibernate的整合，就是这样。
