浅谈SpringMVC+Spring3+Hibernate4开发环境搭建

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

web.xml

 
 
 SpringMVC 
  
  index.jsp 
  
  
   
  
    contextConfigLocation 
    classpath*:config/spring-*.xml 
  
  
  
  
   org.springframework.web.context.ContextLoaderListener 
  
  
  
  
  
  springMVC 
  org.springframework.web.servlet.DispatcherServlet 
   
   contextConfigLocation 
   classpath*:config/spring-servlet.xml 
   
  1 
  
  
  
  springMVC 
  / 
  
  
  
  
  encodingFilter 
  org.springframework.web.filter.CharacterEncodingFilter 
   
   encoding 
   UTF-8 
   
   
   forceEncoding 
   true 
   
  
  
  encodingFilter 
  /* 
  
  
  
  
  
    openSession 
    org.springframework.orm.hibernate4.support.OpenSessionInViewFilter 
  
  
  
  openSession 
  /* 
  
  
 

spring-servlet.xml

spring-hibernate.xml

 
 
   
   
   
     
     
     
     
   
 
   
   
     
     
       
        org.hibernate.dialect.MySQLDialect 
        update 
        true 
        true 
       
     
     
       
         
          classpath*:config/hibernate/hibernate.cfg.xml 
         
       
     
   
 
   
   
     
   
   
   
   
     
     
       
        PROPAGATION_REQUIRED,-Exception 
        PROPAGATION_REQUIRED,-Exception 
        PROPAGATION_REQUIRED,-Exception 
        PROPAGATION_REQUIRED,-Exception 
        PROPAGATION_REQUIRED,-Exception 
        PROPAGATION_REQUIRED,-Exception 
        PROPAGATION_NEVER 
       
     
   
 
  

spring-core.xml

spring-user.xml

 
 
]> 
 
 
   
   
     
   
   
   
     
   
   
   
   
     
   
   
 

hibernate.cfg.xml

下面再来看看Controller

package com.jialin.controller; 
 
import java.io.IOException; 
import java.io.PrintWriter; 
import java.util.List; 
 
import javax.annotation.Resource; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
 
import org.springframework.stereotype.Controller; 
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"; 
  } 
   
}
