SSM整合

SSM整合

整合說明：SSM整合能夠使用多種方式，我們會選擇XML（第三方對象） + 註解（本身new的對象）的方式

整合的思路

• （1）：先搭建整合的環境

• （2）：先把Spring的配置搭建完成

• （3）：再使用Spring整合SpringMVC框架

• （4）：最後使用Spring整合MyBatis框架

create database itcastspringmvc;use itcastspringmvc;create table account( id int primary key auto_increment, name varchar(20), money double);

其中：

表示springmvc的註解包含@Controller的註解。

爲何要包含@Controller註解呢？

1）SpringMVC IOC容器 存在Controller的實例對象

2）Spring IOC容器 存在Controller的實例和Service層實例以及Dao層實例

重疊會引起一些問題：

​ 例如：事務失效、相關注解失效

​ 解決方案一：

​ SpringMVC只掃描 @Controller 註解、不掃描@Service註解

​ Spring不掃描 @Controller 註解

​ 解決方案二：（建議使用）

​ 只讓SpringMVC掃描，不讓Spring掃描

​ 在springMVC的配置中添加

Spring整合SpringMVC框架

目的：在controller中能成功的調用service對象中的方法。（由spring建立對象，注入到Action中使用）

在項目啓動的時候，就去加載applicationContext.xml的配置文件，在web.xml中配置ContextLoaderListener監聽器（默認該監聽器只能加載WEB-INF目錄下的applicationContext.xml的配置文件）。使用contextConfigLocation的屬性讓它加載類路徑下的applicationContext.xml。

web.xml

Mybatis框架

SqlMapConfig.xml

在web項目中編寫SqlMapConfig.xml的配置文件，放置到resources下，編寫核心配置文件

AccountDao.java

在AccountDao接口的方法上添加註解，編寫SQL語句

Spring整合MyBatis框架

applicationContext.xml

目的：把SqlMapConfig.xml配置文件中的內容配置到applicationContext.xml配置文件中

SqlMapConfig.xml配置文件能夠刪除。

在AccountDao接口中添加@Repository註解，也能夠不填加。

拷貝頁面到項目

建立UserController.java

頁面數據發送到Controller，建立Controller

 
 
 
 
 

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

 
 
 
 
 
@Controller@RequestMapping(value = "/user")public class UserController {@Autowiredprivate UserService userService;/*** * 增長用戶 * @param user * @return */@RequestMapping(value = "/save")public String save(User user){//增長int acount = userService.saveUser(user);if(acount>0){//新增成功，返回登陸頁面return "redirect:/login.html";}else{//新增失敗，返回註冊頁面return "redirect:/register.html";}}}

建立接口UserService.java和實現類UserServiceImpl.java

 
 
 
 
 

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

 
 
 
 
 
public interface UserService {/*** * 增長用戶 * @param user * @return */int saveUser(User user);}

 
 
 
 
 

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

 
 
 
 
 
@Servicepublic class UserServiceImpl implements UserService {@Autowiredprivate UserDao userDao;public int saveUser(User user) {return userDao.save(user);}}

若是是註解的方式配置聲明式事務處理，須要添加在UserServiceImpl的類上添加：@Transactional

建立接口UserDao.java

 
 
 
 
 

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

  
  
  
  
  

 
 
 
 
 
//@Repositorypublic interface UserDao {/*** * 增長操做 * @param user * @return */@Insert("insert into user(number,password,mobile)values(#{number},#{password},#{mobile})")int save(User user);}

整合攔截器

【需求】：用戶若是已經登陸

​ 用戶若是沒有登陸，則不能訪問歡迎頁

LoginInterceptor.java

聲明攔截器

建立包com.le.ssm.interceptor

建立類LoginInterceptor.java

【測試】從新啓動，在沒有Session的狀況下，訪問/index/welcome，此時重定向到登陸頁面。
