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

@controller  //类似struts的action 
@requestmapping("/user")

  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")

    string result = "{\"result\":\"error\"}";

    } 
    printwriter out = null; 
    response.setcontenttype("application/json"); 
     
    try {

      out.write(result); 
    } catch (ioexception e) { 
      e.printstacktrace();

  } 
  @requestmapping("/toadduser")
