本文介绍了一个简单的 Spring MVC 控制器示例，展示了如何通过 @ModelAttribute 注解设置 HttpServletRequest 和 HttpServletResponse 对象，并获取 HttpSession。这有助于理解 Spring Web 应用的基本结构。

public class BasicController {


	protected HttpServletRequest request;  
    protected HttpServletResponse response;  
    protected HttpSession session; 
    
    @ModelAttribute  
    public void setReqAndRes(HttpServletRequest request, HttpServletResponse response){  
        this.request = request;  
        this.response = response;  
        this.session = request.getSession();  
    }}
