1.hibernate譯爲「越冬」,指的是給java程序員帶來春天,由於java程序員無需再關心各類sql了;css
2.hibernate經過java類生成數據庫表,經過操做對象來映射成SQL;html
3.hibernate是真正意義上的ORM框架,由於他實現了對象(Object)---->關係(Relation)的映射(Mapping);前端
4.maven項目總體包結構(報錯是eclipse發神經,不用管)java
由於hibernate能夠根據類生成表,因此只需建立數據庫便可;mysql
create database ssh;
該案例實現了一個用戶擁有多部手機的關係程序員

6.實體類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;//一個用戶擁有多部手機 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接口及其實現
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; //繼承HibernateDaoSupport 能夠直接使用CRUD操做 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("進入CoreDaoImpl......"); return super.getHibernateTemplate().findByExample(t); } }
8.模塊dao接口及其實現(只需繼承核心dao便可)
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> { }

9.service接口及其實現
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("進入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頁面測試登陸
<%@ 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="登陸"> </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.項目啓動後,你會發現你的ssh數據庫中多了兩張表User和Phone,本身在插入幾條數據
user表 phone表
13.測試
index.jsp表單中輸入1001和123
result.jsp

14.注意點:我我的以爲ssh框架坑實在是多,我在搭建的過程當中出現了各類各樣的問題,不過最噁心的問題是spring和hibernate存在版本不兼容問題,一開始使用的是spring5+hibernate5,發現報錯,就將hibernate5換成4(應該沒問題了吧),結果仍是報錯,折騰半天,發現雖然Pom版本雖然換成4,可是以前dao層用到的HibernateDaoSupport和spring-context.xml配置中SessionFactory仍是5的版本,誒,智障問題。
