老师，下午好，请教一个问题，

@PostMapping("/reset-password")
public ResponseDto resetPassword(@RequestBody MemberDto memberDto) throws BusinessException { // 同样是调用会抛出错误的函数，为何这一行加不加上 throws BusinessException , 在IDEA中都不会报错
    // 略
    // 重置密码
    memberService.resetPassword(memberDto);
}

public void resetPassword(MemberDto memberDto) throws BusinessException {
}

而

public void imageCode(@PathVariable(value = "imageCodeToken") String imageCodeToken, HttpServletRequest request, HttpServletResponse httpServletResponse) throws Exception { // 同样是调用会抛出错误的函数，为何这一行不加上 throws Exception , 在IDEA中就会报错
   // 略
   ImageIO.write(challenge, "jpg", jpegOutputStream);
}

谢谢老师解答！
