SpringMVC+Hibernate+Spring整合实例（二）

转自：http://blog.****.net/bjyfb/article/details/8998439

这篇接着上篇，把没贴完的代码写完，上篇主要完成了一些公共配置和界面的东西，这篇把后台的代码完成。

首先是web包下属于的control层的类UserController，这相当于Struts中的Action，是重要的类：

[java] view plain copy

packagecom.tgb.web;
importjava.io.IOException;
importjava.io.PrintWriter;
importjavax.annotation.Resource;
importjavax.servlet.http.HttpServletRequest;
importjavax.servlet.http.HttpServletResponse;
importorg.springframework.stereotype.Controller;
importorg.springframework.web.bind.annotation.RequestMapping;
importcom.tgb.entity.User;
importcom.tgb.manager.UserManager;
@Controller
@RequestMapping("/user")
publicclassUserController{
@Resource(name="userManager")
privateUserManageruserManager;
@RequestMapping("/getAllUser")
publicStringgetAllUser(HttpServletRequestrequest){
request.setAttribute("userList",userManager.getAllUser());
return"/index";
}
@RequestMapping("/getUser")
publicStringgetUser(Stringid,HttpServletRequestrequest){
request.setAttribute("user",userManager.getUser(id));
return"/editUser";
}
@RequestMapping("/toAddUser")
publicStringtoAddUser(){
return"/addUser";
}
@RequestMapping("/addUser")
publicStringaddUser(Useruser,HttpServletRequestrequest){
userManager.addUser(user);
return"redirect:/user/getAllUser";
}
@RequestMapping("/delUser")
publicvoiddelUser(Stringid,HttpServletResponseresponse){
Stringresult="{\"result\":\"error\"}";
if(userManager.delUser(id)){
result="{\"result\":\"success\"}";
}
response.setContentType("application/json");
try{
PrintWriterout=response.getWriter();
out.write(result);
}catch(IOExceptione){
e.printStackTrace();
}
}
@RequestMapping("/updateUser")
publicStringupdateUser(Useruser,HttpServletRequestrequest){
if(userManager.updateUser(user)){
user=userManager.getUser(user.getId());
request.setAttribute("user",user);
return"redirect:/user/getAllUser";
}else{
return"/error";
}
}
}

然后是属于manager包下的业务逻辑类，接口UserManager：

[java] view plain copy

packagecom.tgb.manager;
importjava.util.List;
importcom.tgb.entity.User;
publicinterfaceUserManager{
publicUsergetUser(Stringid);
publicList<User>getAllUser();
publicvoidaddUser(Useruser);
publicbooleandelUser(Stringid);
publicbooleanupdateUser(Useruser);
}

实现类UserManagerImpl：

[java] view plain copy

packagecom.tgb.manager;
importjava.util.List;
importcom.tgb.dao.UserDao;
importcom.tgb.entity.User;
publicclassUserManagerImplimplementsUserManager{
privateUserDaouserDao;
publicvoidsetUserDao(UserDaouserDao){
this.userDao=userDao;
}
@Override
publicUsergetUser(Stringid){
returnuserDao.getUser(id);
}
@Override
publicList<User>getAllUser(){
returnuserDao.getAllUser();
}
@Override
publicvoidaddUser(Useruser){
userDao.addUser(user);
}
@Override
publicbooleandelUser(Stringid){
returnuserDao.delUser(id);
}
@Override
publicbooleanupdateUser(Useruser){
returnuserDao.updateUser(user);
}
}

最后是属于dao包底下的DAO层，主要由Hibernate完成。接口UserDao：

[java] view plain copy

packagecom.tgb.dao;
importjava.util.List;
importcom.tgb.entity.User;
publicinterfaceUserDao{
publicUsergetUser(Stringid);
publicList<User>getAllUser();
publicvoidaddUser(Useruser);
publicbooleandelUser(Stringid);
publicbooleanupdateUser(Useruser);
}

实现类UserDaoImpl：

[java] view plain copy

packagecom.tgb.dao;
importjava.util.List;
importorg.hibernate.Query;
importorg.hibernate.SessionFactory;
importcom.tgb.entity.User;
publicclassUserDaoImplimplementsUserDao{
privateSessionFactorysessionFactory;
publicvoidsetSessionFactory(SessionFactorysessionFactory){
this.sessionFactory=sessionFactory;
}
@Override
publicUsergetUser(Stringid){
Stringhql="fromUseruwhereu.id=?";
Queryquery=sessionFactory.getCurrentSession().createQuery(hql);
query.setString(0,id);
return(User)query.uniqueResult();
}
@Override
publicList<User>getAllUser(){
Stringhql="fromUser";
Queryquery=sessionFactory.getCurrentSession().createQuery(hql);
returnquery.list();
}
@Override
publicvoidaddUser(Useruser){
sessionFactory.getCurrentSession().save(user);
}
@Override
publicbooleandelUser(Stringid){
Stringhql="deleteUseruwhereu.id=?";
Queryquery=sessionFactory.getCurrentSession().createQuery(hql);
query.setString(0,id);
return(query.executeUpdate()>0);
}
@Override
publicbooleanupdateUser(Useruser){
Stringhql="updateUserusetu.userName=?,u.age=?whereu.id=?";
Queryquery=sessionFactory.getCurrentSession().createQuery(hql);
query.setString(0,user.getUserName());
query.setString(1,user.getAge());
query.setString(2,user.getId());
return(query.executeUpdate()>0);
}
}

最后外加一个配置spring-beans.xml，放在config.spring包下，负责为各层依赖注入需要的对象：

[html] view plain copy

<?xmlversion="1.0"encoding="UTF-8"?>
<beansxmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<beanid="userDao"class="com.tgb.dao.UserDaoImpl">
<propertyname="sessionFactory"ref="sessionFactory"></property>
</bean>
<beanid="userManagerBase"class="com.tgb.manager.UserManagerImpl">
<propertyname="userDao"ref="userDao"></property>
</bean>
<beanname="userManager"parent="transactionProxy">
<propertyname="target"ref="userManagerBase"></property>
</bean>
</beans>

到此为止，所有的配置和代码完成，部署—运行，运行结果如下图：
