# SSH
Spring+SpringMVC+Hibernate三大框架整合思路导图


# SSH(Spring+SpringMVC+Hibernate)

 1.创建项目，导入jar(spring(15个)＋hibernate(11个)+上传包(2个)………….)

 2.导入页面资源jsp放入到WEB-INF/jsp目录下

3.以分层思想进行分包

![1.项目分层思想分包目录图](1.项目分层思想分包目录图.png)

## 第一章：以xml方式进行整合

#### 1.1 dao层相关：

#####     	1.1.1 dao层接口及实现类

```java
UserDao.java

public interface UserDao {
   public void insertUser(User user);
   public User queryUserByUserNameAndPwd(User user);
}
UserDaoImpl.java
public class UserDaoImpl extends HibernateDaoSupport
        implements UserDao {
    @Override
    public void insertUser(User user) {
        getHibernateTemplate().save(user);
    }
    @Override
    public User queryUserByUserNameAndPwd(User user) {
        DetachedCriteria criteria = DetachedCriteria.forClass(User.class);
        criteria.add(Restrictions.eq("user_name", user.getUser_name()));
        criteria.add(Restrictions.eq("user_pwd", user.getUser_pwd()));
        List<User> list =
                ( List<User>)getHibernateTemplate().findByCriteria(criteria);
       if (list!=null&&list.size()>0)
       {
           return  list.get(0);
       }
        return null;
    }
}

ShopDao.java

public interface ShopDao {
    public List<Shop> queryAllShopList();
    public Shop queryShopById(Integer shop_id);
    public void updateShop(Shop shop);
}
ShopDaoImpl.java
public class ShopDaoImpl extends HibernateDaoSupport implements ShopDao {
    @Override
    public List<Shop> queryAllShopList() {
        List<Shop> list= (List<Shop>)getHibernateTemplate().find("from com.sky.domain.Shop");
        return list;
    }
    @Override
    public Shop queryShopById(Integer shop_id) {
        return   getHibernateTemplate().get(Shop.class,shop_id);
    }
    @Override
    public void updateShop(Shop shop) {
     getHibernateTemplate().update(shop);
    }
}
```

#### 1.3 controller控制层类：

#####       1.2.1 UserController类

```java
@Controller
public class UserController {
    @Resource(name = "userService")
    private UserService userService;
    //跳转到注册页面
    @RequestMapping("/register.action")
    public String register() {
        return "user/register";
    }
    @RequestMapping("/doRegister.action")
    public String toDoRegister(HttpServletRequest request,
                               User user,
                               @RequestParam("picture") MultipartFile picture)
    throws  Exception{
       String imagePath= request.getRealPath("/WEB-INF/image");
       File file=new File(imagePath);
       if (!file.exists()){
           file.mkdirs();
       }
       //1.获取文件名
       String originalName = FilenameUtils.getName(picture.getOriginalFilename());
       System.out.println("=====originalName=====");
       // 2.设置图片名称，不能重复，可以使用uuid
       String uuid = UUID.randomUUID().toString();
       //3.上传
        picture.transferTo(new File(file,uuid + "_" + originalName));
        user.setUser_headimg(uuid + "_" + originalName);
        //5.打印网络地址进行测试是否成功显示图片
        System.out.println("http://localhost"+request.getContextPath() +"/image/"+ user.getUser_headimg());
        //6.调用业务逻辑
        userService.register(user);
        return "user/success";
    }
    @RequestMapping("/login.action")
    public String login() {
        return "user/login";
    }
    @RequestMapping("/dologin.action")
    public String tologin(User user, HttpSession httpSession) {
        User user1= userService.loginUser(user);
        httpSession.setAttribute("userInfo",user1);
        return "user/userinfo";
    }
}
```

#####       1.3.2  ShopController类

```java
@Controller
public class ShopController {
    @Resource(name = "shopService")
    private ShopService shopService;
    @RequestMapping("/shopList.action")
    public  String queryAllShopList(Model model){
        List<Shop> list= shopService.queryShopList();
        model.addAttribute("list",list);
        return "shop/itemList";
    }
    @RequestMapping("/itemEdit.action")
    public String findShopById(Integer id,Model model){
       Shop shop = shopService.queryShopById(id);
       model.addAttribute("shop",shop);
       return "/shop/editItem";
    }
    @RequestMapping("/updateitem.action")
    public String updateShop(Shop shop){
        System.out.print("==shop=="+shop);
       shopService.updateShop(shop);
        return "redirect:shopList.action";
    }
}
```
