Spring+Spring MVC+Hibernate框架搭建实例
前言:这里只是说明整个搭建流程,并不进行原理性的讲解
一 下面所需要用到的数据库配置:
数据库方面,使用mysql创建一个users表,具体代码如下:
1

DROP TABLE IF EXISTS `users`; CREATE TABLE `users` ( `UserID` int (4) NOT NULL AUTO_INCREMENT, `UserName` varchar (16) NOT NULL , ` Password ` varchar (16) NOT NULL , `Telephone` varchar (16) NOT NULL , `Address` varchar (16) NOT NULL , PRIMARY KEY (`UserID`) ) ENGINE=InnoDB AUTO_INCREMENT=8 DEFAULT CHARSET=utf8; -- ---------------------------- -- Records of users -- ---------------------------- INSERT INTO `users` VALUES ( '1' , 'aa' , 'aa12' , 'aa' , 'aa' ); INSERT INTO `users` VALUES ( '2' , 'bb' , 'bb' , 'bb' , 'bb' ); INSERT INTO `users` VALUES ( '3' , 'cc' , 'cc' , 'cc' , 'cc' ); INSERT INTO `users` VALUES ( '7' , 'admin' , 'admin' , '12306' , '北京天安门' ); |
二 创建web项目,并导入相关jar包:
创建一个dynamic web project,然后在WEB-INF/lib下导入spring和hibernate的jar包,嫌麻烦的话也可以使用我用到的jar包,链接:http://pan.baidu.com/s/1kUse26z 。整个项目的结构是这样的:
三 创建视图页面user.jsp:
路径是:/WEB-INF/jsp/user/user.jsp,代码如下:
1
2
3

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE html> < html > < head > < meta http-equiv = "Content-Type" content = "text/html; charset=UTF-8" > < base href="<%=basePath%>"> < title >Insert title here</ title > </ head > < body > < h1 >Message : ${message}</ h1 > </ body > </ html > |
四 根据数据库表的字段建立实体类Users.java:
实体类放在cn.zifangsky.entity包中,这里采用了注解的方式来配置,Users.java代码如下:

package cn.zifangsky.entity; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; @Entity (name= "users" ) public class Users implements java.io.Serializable{ @Id @GeneratedValue (strategy=GenerationType.AUTO) @Column (name= "UserID" ) private Integer userId; @Column (name= "UserName" ,length= 16 ) private String userName; @Column (name= "Password" ,length= 16 ) private String password; @Column (name= "Telephone" ,length= 16 ) private String telephone; @Column (name= "Address" ,length= 16 ) private String address; public Users(){ } public Users(Integer userId, String userName, String password, String telephone, String address) { this .userId = userId; this .userName = userName; this .password = password; this .telephone = telephone; this .address = address; } public Integer getUserId() { return userId; } public void setUserId(Integer userId) { this .userId = userId; } public String getUserName() { return userName; } public void setUserName(String userName) { this .userName = userName; } public String getPassword() { return password; } public void setPassword(String password) { this .password = password; } public String getTelephone() { return telephone; } public void setTelephone(String telephone) { this .telephone = telephone; } public String getAddress() { return address; } public void setAddress(String address) { this .address = address; } } |

六 业务处理DAO,Service和Controller:
(1)UsersDAO.java,在cn.zifangsky.dao这个包中:

package cn.zifangsky.dao; import java.util.List; import org.hibernate.HibernateException; import org.hibernate.Query; import org.hibernate.Session; import org.springframework.orm.hibernate5.HibernateCallback; import org.springframework.orm.hibernate5.support.HibernateDaoSupport; import cn.zifangsky.entity.Users; public class UsersDAO extends HibernateDaoSupport{ public List<Users> getAllUser(){ Object execute = super .getHibernateTemplate().execute( new HibernateCallback<Object>() { public Object doInHibernate(Session session) throws HibernateException { String hql= "from users" ; Query query = session.createQuery(hql); return query.list(); } }); return (List<Users>) execute; } } |
(2)UserService.java,在cn.zifangsky.service这个包中:

package cn.zifangsky.service; import cn.zifangsky.dao.UsersDAO; public class UserService { private UsersDAO userDao; public int userCount(){ return userDao.getAllUser().size(); } public UsersDAO getUserDao() { return userDao; } public void setUserDao(UsersDAO userDao) { this .userDao = userDao; } } |
(3)UserController.java,在cn.zifangsky.controller这个包中:

package cn.zifangsky.controller; import javax.annotation.Resource; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.ModelAndView; import cn.zifangsky.service.UserService; @Controller @RequestMapping ( "/user" ) public class UserController { @Resource (name= "userService" ) private UserService service; @RequestMapping (value= "/manager" ,method=RequestMethod.GET) public ModelAndView hello2(){ ModelAndView mv = new ModelAndView(); mv.addObject( "message" , "HelloMVC" ); mv.setViewName( "user" ); return mv; } @RequestMapping (value= "/count" ,method=RequestMethod.GET) public ModelAndView count(){ int c = service.userCount(); ModelAndView mv = new ModelAndView(); mv.addObject( "message" , c); mv.setViewName( "user" ); return mv; } } |
从上面的代码可以看出,定义了两个请求,分别是:http://localhost:8080/SpringDemo/user/manager 和 http://localhost:8080/SpringDemo/user/count ,分别返回一个字符串和users这个表中数据的条数。下面我们将对这两个请求进行测试
七 测试:
测试结果如下:
http://localhost:8080/SpringDemo/user/manager
http://localhost:8080/SpringDemo/user/count
可以看出,这个框架已经搭建成功了
针对这些问题鉴于这里文字图片描述的方式可能不太好理解,我这里找朋友录了一些视频提供给大家,相信大家看了会发现有些东西其实很简单很好理解。如果想学习Java 线程,框架,数据结构,web和数据库等技术可以加群:318261748 群里免费提供学习资料和交流环境,不定期会有技术视频免费分享给大家。
注:如果在项目启动时报错的话,第一是检查配置文件中是不是有哪个地方写错了,第二是注意看下/WEB-INF/lib下有没有aopalliance.jar和aspectjweaver-1.5.4.jar这两个jar包。因为我刚开始时就是因为没有这两个jar包,在项目启动时各种报错,真的挺坑的
