Sprｉngboot 錯誤信息：Required String parameter 'loginname' is not present 引發的研究

@PostMapping("/reg/change")
public CommonSdo change(
 @RequestParam(value = "oldPassword") String oldPassword,
 @RequestParam(value = "newPassword") String newPassword,
 @RequestParam(value = "confirmPassword") String confirmPassword){
 Member member = getCurrentMember();
 System.out.println("oldPassword"+oldPassword);


=============================================================

這個問題就是參數傳遞問題　@RequestParam　　@RequestBody　　@PathVariable　，．．．．有時間研究一下

@RequestParam

@RequestBody　可以寫一個ｄｔｏ類 @RequestBody　PasswordDto dto

public class PasswordDto{

 String oldPassword;
 String newPassword;
 String confirmPassword;
get...
set...
}
