问题描述

我正在尝试使用 thymeleaf 和 Spring boot 构建简单的搜索选项卡.这是我的代码和 html 文件.

I am trying to build simple search tab with thymeleaf and Spring boot. Here is my codes and html files.

scCountry.html

scCountry.html

  <form class="form-inline" action="#"  th:action="@{/search}" modelAttribute="sInput" th:object="${sInput}" method="post">
                <input class="form-control mr-sm-2" type="text" placeholder="Search" th:field="*{keyWord}">
                <input type="submit" value="Submit" />
      <!--      <button class="btn btn-success" type="Submit" value="Submit">Search</button> -->
            </form>

控制器类

 @GetMapping(value="/search")
    public String SearchForm(Model model) {

         SearchInput sInput = new SearchInput();
        model.addAttribute("sInput",sInput);

        return "scCountry";
    }

    @PostMapping(value="/search")
    public String SearchResult(@ModelAttribute("sInput") SearchInput sInput, BindingResult bindingResult, Model model) {
        if (bindingResult.hasErrors()) {
            return "scCountry";
        }

        SearchVO searchVO = null;
        try {
            searchVO = webServices.searchAll(sInput.getKeyWord());
        } catch (TwitterException e) {
            e.printStackTrace();
        }

        model.addAttribute("searchVO",searchVO);

        return "scSearch";
    }

模态类

public class SearchInput {

    private String keyWord;
    public String getKeyWord() {
        return keyWord;
    }
    public void setKeyWord(String keyWord) {
        this.keyWord = keyWord;
    }
    public SearchInput() {
    }
    public SearchInput(String keyWord) {
        this.keyWord = keyWord;
    }
}

我收到错误消息:Bean 名称sInput"的 BindingResult 和普通目标对象均不可用作请求属性

I am getting the error : Neither BindingResult nor plain target object for bean name 'sInput' available as request attribute

我尝试了以下解决方案，该平台已回答:

I tried the solutions in below which is answered in this platform:

使用 thymeleaf 的 html 表单验证不起作用弹簧靴

Thymeleaf 注册页面 - 处理器执行期间出错'org.thymeleaf.spring4.processor.attr.SpringInputGeneralFieldAttrProcessor'

SpringInputGeneralFieldTagProcessor 中的 Spring Thymeleaf TemplateProcessingException

使用带有请求参数的 thymeleaf 中的搜索功能

如果我使用下面的表格，它就可以工作.

If I use the form like below,It is working.

<form class="form-inline"   action="/search" method="post">
                <input class="form-control mr-sm-2" type="text"  id="keyWord" name="keyWord" value=""  placeholder="Search" >
                <input type="submit" value="Submit" />
      <!--      <button class="btn btn-success" type="Submit" value="Submit">Search</button> -->
            </form>

但我想知道这两天我错过了什么?

But I wondering what i am missing for two days?

有人可以帮我吗?

我想知道为什么 scCountry.html 中的 "th:object="${sInput}" 没有在模型中获取我将其放入同名模型中的对象?

I want to know why "th:object="${sInput}" in the scCountry.html is not fetching the object in the model which i put it in model with the same name?
