Controller代码：

package springMVC.Test01;

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

import org.springframework.web.servlet.ModelAndView;

@Controller  
public class Login {
    @RequestMapping(value="/jsp/test1")  
       public ModelAndView login(){  
        //验证传递过来的参数是否正确，否则返回到登陆页面。  
       
            //指定要返回的页面为succ.jsp  
            ModelAndView mav = new ModelAndView("/jsp/test1");  
            //将参数返回给页面  
            mav.addObject("userName","guoyong");  
            mav.addObject("passWord", "guoyong123");  
            return mav;  
  
    } 
}
