Question

我尝试使用表单操作在按钮单击上调用带有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，几乎相同的代码绝对正常工作在其他一些项目中很好。

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;
    }



}

这是包含Thymeleaf的HTML文件：

这里我试图在保存按钮上点击/问题/保存/发布映射，不幸的是，onSaveClick方法没有调用。请帮帮我。感谢

项目结构：

单击“保存”按钮后的

/ question / save已按日志显示进行映射，我也可以使用PostMan直接调用该方法，但是，我无法通过保存按钮上的Thymeleaf html页面执行此操作。

来自浏览页面来源的源代码：

Answer 1

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。

Answer 2

您的控制器已映射“/ question / save”

<强> BUT

你的行动有一个“/ question / save /”

注意尾随斜线。

使用thymeleaf方法的Spring Boot不会调用
