    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class HelloController {
    
        @RequestMapping(value = "/hello.do")
        public String getHello(String userName, Model model) {
            System.out.println("----:" + userName);
            model.addAttribute("hello", "hello, " + userName);
            return "hello";
        }
