**HelloController:**

package controller;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.servlet.ModelAndView;
    @Controller
    @RequestMapping("/test")
    public class HelloController {
    
        @RequestMapping("/hello")
        public ModelAndView del(HttpServletRequest request,
                                HttpServletResponse response) {
            System.out.println("----del----");
            return new ModelAndView("/hello", "message", "你好");
        }
    }
