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

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>

Controller.class

 @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";
    }

Modal Class

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;
    }
}

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> -->

Was facing a similar problem. This didn't work:

<input type="text" th:field="*{content}">

This did:

<input type="text" field="*{content}" name="content">

th:field="*{sInput.keyWord}"

should be

th:field="*{keyWord}"

When using *{...} expressions, the th:object is assumed.

  • I tried it.But nothing has changed.Also according to the error description, th:object="${sInput}" is not available before than keyWord.I am editing the question as "*{keyWord}" – Cocuthemyth Dec 13 '18 at 13:12
  • So what happens when you print out ` – Metroids Dec 13 '18 at 15:34
  • I added the error log and Model Class in the above.I am getting the error : "There was an unexpected error (type=Internal Server Error, status=500). Error during execution of processor 'org.thymeleaf.spring5.processor.SpringInputGeneralFieldTagProcessor' (template: "scCountry" - line 31, col 86)". Also the page is not opening.The error is occuring. – Cocuthemyth Dec 13 '18 at 20:59

Do the below modifications in your controller and try

@GetMapping(value="/search")

public ModelAndView SearchForm(Model model, SearchInput sInput) {

    return new ModelAndView("scCountry");

}

Hope you will get solved your error.

A was have the same proplem. That helped me. Old code -

@PostMapping()
public String create(@Valid AdditionalContact additionalContact, BindingResult bindingResult, BindingResult bindingResultForId, Model model) {
   if (bindingResult.hasErrors() || bindingResultForId.hasErrors())
        model.addAttribute("contacts", additionalContact.getAll());
    return "additionalContact/create";
    additionalContactService.save(additionalContact);
    return "redirect:contacts";
    }

new code

@PostMapping()
public String create(@Valid @ModelAttribute("contact") AdditionalContact additionalContact, BindingResult bindingResult,
                         BindingResult bindingResultForId) {

if (bindingResult.hasErrors() || bindingResultForId.hasErrors())
return "additionalContact/create";

additionalContactService.save(additionalContact);
return "redirect:contacts";
}

Simply take off the "th:" from the "th:field" and you are good to go!
