常規路徑get提交
前端頁面
<%-- Created by IntelliJ IDEA.

瀏覽器傳遞地址
controller後端處理程式碼
@GetMapping("/add") public String test2( String a,String b,Model model){ String res=a+b; model.addAttribute("msg","結果為："+res); return "hello"; }
注意：springMVC的Controller類裡面Mapping對映下所有方法裡的引數都可匹配瀏覽器地址傳遞的引數
用Restful方式傳遞引數，可在需要傳遞的引數前加
@PathVariable
註解
可用
@RequestMapping
不同的延申註解接收相同地址的不同提交方式的資料
如下
post提交頁面

/2/3為restful傳輸方式的資料用url傳遞
後端Controller類程式碼：
@Controller
public class restfulController {
@RequestMapping(value = "/add/{a}/{b}",method = {RequestMethod.POST})
public String test(@PathVariable int a, @PathVariable int b, Model model){
model.addAttribute("msg","結果為："+a+b);
return "hello";
}
最後hello.jsp顯示頁面，補充
