@PathVariable获取url中的数据
@RequestParam获取请求参数的值
@GetMaping组合注解，是@RequestMapping(method=GET)的缩写

@RestController
public class Controller {
    @RequestMapping(method = GET, value="/hello/{id}/{name}")
    public String sayHello(@PathVariable("id")Integer id, @PathVariable("name") String name) {
        return "id:" + id + " name:" + name + "\n";
    }

    @GetMapping("/helloworld")
    public String helloWorld() {
        return "helloWorld";
    }

    @RequestMapping(method=GET, value="/greeting")
    public String greetingFunc(@RequestParam(value="name", defaultValue = "World") String name) {
       return "name " + name;
    }
}
