【web开发】基于注解spring的多方法请求的一种controller实现

@Controller
@RequestMapping(value="mainPage")  // 类对应的请求url
public class MainPageController extends AbstractController{
                                                                                                                                                     // 实现Controller接口中的handleRequestInternal方法, 跳转时默认情况下会被调用
    public ModelAndView handleRequestInternal(HttpServletRequest req,
            HttpServletResponse res) throws Exception {
    	
    	HashMap<String, Object> model = new HashMap<String, Object>();
	// TODO: add the model data
        
        return new ModelAndView("mainPage",model);    // 'mainpage' is the view name   
    }

    // 在请求url中带参数method=changePageNo时，该函数被调用
    @RequestMapping(params = "method=changePageNo")
    public ModelAndView changePageNo(@RequestParam("pageNo")String pageNo, 
				     HttpSession session) throws Exception {  	 	
	session.setAttribute("pageNo", pageNo); 
		
    	HashMap<String, Object> model = new HashMap<String, Object>();
	// TODO: add the model data

    	return new ModelAndView("mainPage",model); 
    }   
    
    // ...可实现更多的对应不同参数url的控制方法
}
