SpringMVC+Spring3+Hibernate4开发环境搭建

http://blog.csdn.net/shan9liang/article/details/9117233

早期的项目比较简单，多是用JSP 、Servlet + JDBC 直接搞定，后来使用 Struts1(Struts2)+Spring+Hibernate, 严格按照分层概念驱动项目开发，这次又使用 Spring MVC取代Struts来进行开发。

MVC已经是现代Web开发中的一个很重要的部分，下面介绍一下SpringMVC+Spring3+Hibernate4的开发环境搭建

先大致看一下项目结构：

 

具体的代码不再演示，主要是走了一个很平常的路线，mvc-servcie-dao-hibernate的结构， 源码可以下载，主要看一下配置文件。解释见注释

 import org.springframework.web.bind.annotation.RequestMapping;

 import com.jialin.entity.User;
 import com.jialin.service.IUserManager;

 @Controller   //类似Struts的Action
 @RequestMapping("/user")
 public class UserController {

     @Resource(name="userManager")  // 获取spring配置文件中bean的id为userManager的，并注入
     private IUserManager userManager;

     @RequestMapping("/addUser")   // 请求url地址映射，类似Struts的action-mapping
     public String addUser(User user){
         if(userManager.addUser(user))
         {
             // 重定向
             return "redirect:/user/getAllUser";
         }else
         {
             return "/fail";
         }

     }

     @RequestMapping("/updateUser")
     public String updateUser(User user,HttpServletRequest request){
         if (userManager.updateUser(user))
         {
             user = userManager.getOneUser(user);
             request.setAttribute("user", user);
             return "/UserEdit";
         }else
         {
             return "/fail";
         }

     }

     @RequestMapping("/delUser")
     public void delUser(User user,HttpServletResponse response){
         String result = "{\"result\":\"error\"}";

         if(userManager.delUser(user)){
             result = "{\"result\":\"success\"}";
         }
         PrintWriter out = null;
         response.setContentType("application/json");

         try {
             out = response.getWriter();
             out.write(result);
         } catch (IOException e) {
             e.printStackTrace();
         }

     }
     @RequestMapping("/toAddUser")
     public String toAddUser(){
         return "/UserAdd";
     }

     @RequestMapping("/toUpdateUser")
     public String toUpdateUser(User user,HttpServletRequest request){
         User user1=userManager.getOneUser(user);

         request.setAttribute("user1", user1);

         return "/UserEdit";
     }

     @RequestMapping("/getAllUser")
     public String getAllUser(HttpServletRequest request){

         List userList=userManager.getAllUser();

         request.setAttribute("userlist", userList);

         return "/UserMain";
     }

 }
