在DemoRun中添加如下代码：

1 import org.springframework.boot.SpringApplication;
2 import org.springframework.boot.autoconfigure.SpringBootApplication;
3 
4 @SpringBootApplication
5 public class DemoRun {
6     public static void main(String[] args) {
7         SpringApplication.run(DemoRun.class, args);
8     }
9 }

在DemoController中添加如下代码：

 1 import org.springframework.stereotype.Controller;
 2 import org.springframework.ui.Model;
 3 import org.springframework.web.bind.annotation.RequestMapping;
 4 import org.springframework.web.bind.annotation.RequestParam;
 5 
 6 @Controller
 7 public class DemoController {
 8     @RequestMapping("/greeting")
 9     public String greeting(
10             @RequestParam(value = "name", required = false, defaultValue = "name") String name,
11             @RequestParam(value = "age", required = false, defaultValue = "age") String age,
12             @RequestParam(value = "sex", required = false, defaultValue = "男") String sex,
13             Model model) {
14         model.addAttribute("name", name);
15         model.addAttribute("age", age);
16         model.addAttribute("sex", sex);
17         return "greeting";
