jqueryを使用してフィールドを表示/非表示にするビュー(jsp)があります。jqueryを使用して、ajaxを使用してデータをコントローラー(spring mvc)に投稿しています。ページに値を入力するだけでうまくいきますが、リンクをクリックして2つのテキストボックスを再表示し、それらに値を入力してコントローラーに送信すると、この例外が発生しました。スプリング ログを確認したところ、すべてのプロパティがスプリングにバインドするように変換されていることがわかりますが、その直後に例外が発生しました。以下は、ログで確認できるものです。すべてのパラメータを何度も確認しましたが、jsp/js/java に欠落やスペルミスはありません。どんな助けでも大歓迎です

完全なスタック トレースは大歓迎です。問題は、Spring がメソッド パラメータの 1 つを変換できなかった可能性があります。そのメソッドをリファクタリングする必要があります。パラメーターが多すぎます。すべてのパラメーターをラップする dto を作成できます (Spring によって提供されるパラメーターを除く)。

編集：

@RequestParam多くの注釈を使用する代わりに。すべてのメソッド パラメータを 1 つのラッパー オブジェクト (DTO) にラップできます。

例： 

public class MyWrapperDTO {
    private String someStrValue;
    private String anotherStrValue;
    private int someIntValue;

    // getters/setters omitted
}

@ModelAttributeここから、またはを使用して 2 つのオプションを選択できます。@RequestBody

最初のものについて： 

@Controller
public class Controller {
    @RequestMapping(value = "/mypage/view")
    public ModelAndView viewPage() {
        MyWrapperDTO dto = new MyWrapperDTO();
        // you could provide default values for your form here
        return new ModelAndView("/mypage").
            .addObject("form", dto);
    }

    @RequestMapping(value = "/mypage/save", method = RequestMethod.POST)
    @ResponseBody
    public void doSomething(@ModelAttribute("form") MyWrapperDTO dto) {
        // process your ajax call here
        // do something
    }
}

jsp は次のようになります。

<spring:url var="myAjaxCall" value="/mypage/save" />

<!-- you should use spring form tag -->
<form:form commandName="form" action="${myAjaxCall}">
   <form:input path="someStrValue"></form:input>
   <form:input path="anotherStrValue"></form:input>
   <form:input path="someIntValue"></form:input>
   <input type="submit" value="Submit"></input>
</form:form>

2 番目のオプション ( @RequestBody)。JSON オブジェクトを送信していると仮定します (これには jquery が含まれます)。 

@Controller
public class Controller {
    @RequestMapping(value = "/mypage/view")
    public ModelAndView viewPage() {
        MyWrapperDTO dto = new MyWrapperDTO();
        // you could provide default values for your form here
        return new ModelAndView("/mypage").
            .addObject("form", dto);
    }

    @RequestMapping(value = "/mypage/save", method = RequestMethod.POST)
    @ResponseBody
    public void doSomething(@RequestBody MyWrapperDTO dto) {
        // process your ajax call here
        // do something
    }
}

あなたのjspのために： 

<spring:url var="myAjaxCall" value="/mypage/save" />

<script type="text/javascript">
   $(document).ready(function() {
      $(document).on('click', '#submit', function() {
          // not the best way to do it
          var data = {
            'someStrValue': $('#someStrValue').val(),
            'anotherStrValue': $('#anotherStrValue').val(),
            'someIntValue': $('#someIntValue').val()
          };

          // use jQuery.ajax
          jQuery.ajax({
              'data': JSON.stringify(data),
              'type': 'POST',
              'ur': '${myAjaxCall}',
              'success': function(data) {
                   // yehey!
               }
          });
      });
    });
</script>

<!-- you should use spring form tag -->
<form:form commandName="form">
   <form:input id="someStrValue" path="someStrValue"></form:input>
   <form:input id="anotherStrValue" path="anotherStrValue"></form:input>
   <form:input id="someIntValue" path="someIntValue"></form:input>
   <button id="submit" type="button">Submit</button>
</form:form>

Spring は、ラッパー オブジェクトへの変換/バインディングを処理します。2 番目のオプションでは、クラスパスにjacksonが必要です。
