上一个项目，新建一个类

代码

package cn.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.servlet.ModelAndView;
    
    
    /*ControllerMvc是一个基于注解的控制器。
    可以同时处理多个请求动作，并且无须实现任何接口
    org.springframework.stereotype.Controller注解用于指示该类是一个控制器*/
    
    @Controller
    public class ControllerMvc{
    	
    /*	org.springframework.web.bind.annotation.RequestMapping注解
    	用来映射请求的方法等。本例用来映射"/zhushi.html"
    	index注释一个普通的方法
    	该方法返回一个包含视图名或视图名和模型的ModelAndView对象*/
    	
    	@RequestMapping(value="/zhushi.html")
    	public ModelAndView index(){
    		ModelAndView modelAndView=new ModelAndView();
    		modelAndView.setViewName("index");   
    		modelAndView.addObject("message", "hello zhushi MVC");
    		return modelAndView;
    	}
    }
