javaweb各种框架组合案例(三)：maven+spring+springMVC+hibernate
1.hibernate译为“越冬”，指的是给java程序员带来春天，因为java程序员无需再关心各种sql了；
2.hibernate通过java类生成数据库表，通过操作对象来映射成SQL；
3.hibernate是真正意义上的ORM框架，因为他实现了对象（Object）---->关系（Relation）的映射（Mapping）；
4.maven项目整体包结构（报错是eclipse发神经，不用管）
因为hibernate可以根据类生成表，所以只需创建数据库即可;
create database ssh;
该案例实现了一个用户拥有多部手机的关系

6.实体类User和Phone
package com.xiaog.entity; import java.util.List; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.JoinColumn; import javax.persistence.OneToMany; import javax.persistence.Table; @Entity @Table(name="user") public class User { @Id @GeneratedValue(strategy=GenerationType.IDENTITY) private Integer id; private String username; private String password; @OneToMany(targetEntity=Phone.class) @JoinColumn(name="user_id") private List<Phone> phones;//一个用户拥有多部手机 public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } 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 List<Phone> getPhones() { return phones; } public void setPhones(List<Phone> phones) { this.phones = phones; } @Override public String toString() { return "User [id=" + id + ", username=" + username + ", password=" + password + ", phones=" + phones + "]"; } }

7.核心dao接口及其实现
package com.xiaog.core.dao; import java.util.List; public interface CoreDao<T> { int insert(T t); int delete(int id); int update(T t); T getOne(int id); List<T> getList(T t); }
package com.xiaog.core.dao.impl; import java.lang.reflect.ParameterizedType; import java.util.List; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.orm.hibernate4.support.HibernateDaoSupport; import com.xiaog.core.dao.CoreDao; import com.xiaog.entity.User; //继承HibernateDaoSupport 可以直接使用CRUD操作 public class CoreDaoImpl<T> extends HibernateDaoSupport implements CoreDao<T> { private Class<T> clazz; private final static Logger logger = LoggerFactory.getLogger(CoreDaoImpl.class); @SuppressWarnings("unchecked") public CoreDaoImpl() { this.clazz = (Class<T>)((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0]; } @Override public int insert(T t) { return (int) super.getHibernateTemplate().save(t); } @Override public int delete(int id) { super.getHibernateTemplate().delete(new User() {{setId(id);}}); return 1; } @Override public int update(T t) { super.getHibernateTemplate().update(t); return 1; } @Override public T getOne(int id) { return super.getHibernateTemplate().get(clazz, id); } @Override public List<T> getList(T t) { //logger.info("进入CoreDaoImpl......"); return super.getHibernateTemplate().findByExample(t); } }
8.模块dao接口及其实现（只需继承核心dao即可）
package com.xiaog.dao; import com.xiaog.core.dao.CoreDao; import com.xiaog.entity.User; public interface UserDao extends CoreDao<User> { }
package com.xiaog.dao; import com.xiaog.core.dao.CoreDao; import com.xiaog.entity.Phone; public interface PhoneDao extends CoreDao<Phone> { }
package com.xiaog.dao.impl; import org.springframework.stereotype.Repository; import com.xiaog.core.dao.impl.CoreDaoImpl; import com.xiaog.dao.UserDao; import com.xiaog.entity.User; @Repository public class UserDaoImpl extends CoreDaoImpl<User> implements UserDao { }
package com.xiaog.dao.impl; import org.springframework.stereotype.Repository; import com.xiaog.core.dao.impl.CoreDaoImpl; import com.xiaog.dao.PhoneDao; import com.xiaog.entity.Phone; @Repository public class PhoneDaoImpl extends CoreDaoImpl<Phone> implements PhoneDao { }
9.service接口及其实现
package com.xiaog.service; import com.xiaog.entity.User; public interface UserService { User login(User user); }
package com.xiaog.service.impl; import java.util.List; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.xiaog.dao.UserDao; import com.xiaog.entity.User; import com.xiaog.service.UserService; @Service public class UserServiceImpl implements UserService { @Autowired private UserDao userDao; private final static Logger logger = LoggerFactory.getLogger(UserServiceImpl.class); @Override public User login(User user) { //logger.info("进入UserServiceImpl......"); List<User> users = userDao.getList(user); logger.info("users="+users); if(users!=null&&users.size()>0) { return users.get(0); }else { return null; } } }
10.controller
package com.xiaog.controller; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import com.xiaog.entity.User; import com.xiaog.service.UserService; @Controller @RequestMapping("/user") public class UserController { @Autowired private UserService userService; private final static Logger logger = LoggerFactory.getLogger(UserController.class); @RequestMapping(value = "/login",params= {"username","password","username!=","password!="}) public String login(Model model,User user) { logger.info("user(request)="+user); user = userService.login(user); logger.info("user="+user); model.addAttribute("user", user); return "result"; } }
11.jsp页面测试登录
<%@ 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> <form action="user/login" method="post"> <div> <label>username</label> <input type="text" name="username"/> </div> <div> <label>password</label> <input type="password" name="password"/> </div> <div> <input type="submit" value="登录"> </div> </form> </body> </html>
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!doctype html> <html> <head> <meta charset="UTF-8"> <title></title> </head> <body> username=${user} </body> </html>
12.项目启动后，你会发现你的ssh数据库中多了两张表User和Phone，自己在插入几条数据
user表 phone表
13.测试
index.jsp表单中输入1001和123
result.jsp

14.注意点：我个人觉得ssh框架坑实在是多，我在搭建的过程中出现了各种各样的问题，不过最恶心的问题是spring和hibernate存在版本不兼容问题，一开始使用的是spring5+hibernate5，发现报错，就将hibernate5换成4（应该没问题了吧），结果还是报错，折腾半天，发现虽然Pom版本虽然换成4，但是之前dao层用到的HibernateDaoSupport和spring-context.xml配置中SessionFactory还是5的版本，诶，智障问题。
