我在从用户那里获取密码值时遇到问题，我想在URL路径中使用此密码，我将百里香叶用作模板引擎。
这是我的控制器
@RequestMapping(value = "/findEvent/{passcode}", method = RequestMethod.POST)
public String findEvent(@PathVariable("passcode") String passcode,
final RedirectAttributes redirectAttributes, Model model) {
Event event=eventService.findByPassCode(passcode);
List<Question> questions=questionService.findQuestionsByPasscode(passcode);
model.addAttribute("questions",questions);
return "questions";
}
这是我的html页面
addEvent.html
<!DOCTYPE html>

如果您希望表单操作URL包含表单本身的值，那么您需要一个onSubmit处理程序来更新表单字段中的URL。
表单值仅自动包含在POST请求的body中，或作为[[0]请求的query parameters。

您的关键字是GET。搜索一下 ;）query string in spring
