Spring+Hibernate+SpringMVC整合配置（注解式）

概述：近年来，注解式开发越来越流行，虽然不如xml式开发更优秀，但是它的简单易上手仍然吸引大多数程序员的追捧，熟练掌握注解式开发已经称为程序员不可或缺的技能之一！

下面将使用我最近的一个书城小项目为大家带来开发的一些必要配置:

注：jdk1.8+web3.1

1.整体结构：



2.Maven的pom依赖：

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/gdq?characterEncoding=UTF-8
jdbc.username=root
jdbc.password=123456

7.bean层实现
package com.gdq.bean;
import java.util.Date;
import java.util.Set;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.OneToOne;
import javax.persistence.Table;
import org.springframework.format.annotation.DateTimeFormat;
@Entity
@Table(name = "tb_user")
public class User {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;
@Column(length = 20)
private String username;// 用户名
private String password;// 密码
@Column(length = 2)
private String gender;// 性别
@Column(length = 100)
private String email;// 邮箱
@Column(length = 11)
private String telephone;// 电话
@Column(length = 200)
private String introduce;// 简介
private String activeCode;// 激活码
@Column(length = 5)
private String role;// 角色
private int state;// 0代表未激活，1代表已激活，2代表注销
@DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss")//springMVC自动格式化
private Date registTime;// 注册时间
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}

}
}8.dao层实现

@Repository
public class UserDaoImpl extends HibernateDaoSupport implements UserDao {

@Autowired
private SessionFactory factory;

@PostConstruct
public void injectSessionFactory() {
super.setSessionFactory(factory);
}
public User insertUser(User user){
getHibernateTemplate().save(user);
return user;
}

9.service层实现

@Service
@Transactional
public class UserServiceImpl implements UserService{
@Autowired
private UserDao userDao;
public User regUser(User user) throws UserException {
return userDao.insertUser(user);
}

10.controller层实现

@Controller
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/RegistServlet")
public String register(User user) throws UserException {
if(userService.regUser(user)!=null) {
//发送激活码
return "registersuccess";
}else {//失败跳转回去
return "register";
}
}
