这个问题在这里已有答案：
我试图用按钮单击使用表单操作调用一个带有post贴图的java方法，我尝试了很多，不幸的是，该方法没有调用，令我震惊的是，几乎相同的代码在其他项目中工作得非常好 .
这是控制器类：
@Controller
@RequestMapping("/question")
public class QuestionController {
@Autowired
GenericClient client;
@GetMapping("/")
public ModelAndView createDashboardView(){
ModelAndView modelAndView = new ModelAndView("views/question");
List<QuestionDTO> questions = client.genericClient(null, "question/fetchAllQuestions");
QuestionsList questionsList = new QuestionsList();
questionsList.setId1(questions.get(0).getId());
questionsList.setQuestion1(questions.get(0).getDescription());
questionsList.setId2(questions.get(1).getId());
questionsList.setQuestion2(questions.get(1).getDescription());
questionsList.setId3(questions.get(2).getId());
questionsList.setQuestion3(questions.get(2).getDescription());
modelAndView.addObject("questionsList", questionsList);
return modelAndView;
}
@PostMapping("/save")
public ModelAndView onSaveClick(QuestionsList questionsList, BindingResult result){
ModelAndView modelAndView = new ModelAndView("views/question");
System.out.println("Inside method");
System.out.println(questionsList.getQuestion2());
return modelAndView;
}
}
这是Thymeleaf的HTML文件：

在这里，我试图在Save按钮上调用/ question / save / post mapping，不幸的是，onSaveClick方法没有调用 . 请帮帮我 . 谢谢
项目结构：
单击“保存”按钮后的“网络”选项卡：

/ question / save正如日志中所示进行映射，并且我也可以使用PostMan直接调用该方法，但是，我无法在保存按钮单击的Thymeleaf html页面上执行此操作 .

最后，布局文件有问题，导致点击按钮由于某种原因自动执行GET而不是POST .
删除布局文件后，每件事都有效 .
你的控制器有映射“/ question / save”
BUT
你的行动有一个“/ question / save /”的网址
注意尾随斜线 .
