okですので、forループとその内部のフォームに問題があります。更新しようとしているものの、取得し続けている複数のユーザーがいます。Thymeleaf投稿用フォームforループ用

java.lang.IllegalStateException：BindingResultもBean名 'user'のプレーン・ターゲット・オブジェクトもリクエスト属性

として使用できません。私は、各フォームのリストオブジェクト自身を参照しようとしていますので、それは私のため、いずれも行いません

...

コード：

<th:block th:each="user : ${users}"> 
    <tr class="user-row"> 
     <td > 
      <p th:text="${user.name}"></p> 
      <p th:text="${user.lastName}"> </p> 
     </td> 
     <td th:text="${user.email}"></td> 
     <td>Secured</td> 

     <td> 
      <th:block th:each="role : ${user.roles}"> 
       <p th:text="${role.role}"></p> 
      </th:block> 
     </td> 

     <th:block th:switch="${user.active}"> 
      <td th:case="1">Yes</td> 
      <td th:case="2">No</td> 
     </th:block> 
     <td></td> 
     <td class="user-edit"> 
      <i class="material-icons red-text text-darken-2">create</i> 
     </td> 
    </tr> 
    <tr class="user-dropdown"> 
     <form th:action="@{/admin/user/update}" method="post" th:object="${user}"> 

      <input type="hidden" th:field="*{id}" value="*{id}" /> 
     </form> 
    </tr> 
</th:block> 
......

注：私は行くのを回避したいと思いますメソッドを取得し、新しいユーザーを挿入する私のコントローラで（またはそれは唯一の方法ですか？）

何か助けていただければ幸いです！ありがとう！私は、リスト1

をrefferencingていた場合にそれがなぜ起こるか

EDIT（追加完全なエラーとコントローラ）

私はエラーが何を意味するのか取得するには、ユーザーオブジェクトは、私は好奇心...存在しません。

あなたはthymeleaf問題がth：それぞれにあるのですか？要求内でユーザーを見つけることが予想されるため、オブジェクトで不平を言う可能性が高くなります。私はthで何か問題を見ることができません：それぞれ – kimy82

<form th:action="@{/admin/user/update}" method="post" th:object="${user}"> 
    <input type="hidden" th:field="*{id}" value="*{id}" /> 
</form> 


<form th:action="@{/admin/user/update}" method="post" th:object="${user}"> 
    <input type="hidden" th:value="*{id}" id="id" name="id"/> 
</form>

@ vibetribe93 http://www.thymeleaf.org/doc/tutorials/3.0/thymeleafspring.html。「6.1コマンドオブジェクトの処理」の制限：オブジェクトとフォーム。 th：フィールドは、モデル属性であるフォームバッキングBeanで評価されます。 – neuo

私はこの問題は、目でもっとあると思う：目よりもオブジェクト：各番目として：私は上記のコメントのように、それぞれが正常に見えます。

これは$ {seedStarter}のような式は有効ですが、 $ {seedStarter.data}はあなたのことをmeants

ではないであろうことを意味します は、彼らが言うthmeleaf documentation を見てくださいユーザーオブジェクトから来ているユーザーは有効ではありません。それは要求から完全に来なければなりません。 したがって、ページを呼び出すコントローラーでユーザーをmodelAttributeとして設定する必要があります。

model.addAttribute("user", <user>);

ただし、お客様のそれぞれのフォームが必要な場合がありますので、ご理解いただいております。

希望に役立ちます。

ありがとう、私はそれが形式ではないことを理解しているので、私は単純なオブジェクトでこの問題を既に持っていた。私にあなたにこれを聞かせてください。フォーム自体のアイデアは、すでにフィールドに入力されているドロップダウン行になります。私の質問は、私は属性として新しいユーザーオブジェクトを追加する場合、フォームからそれらのフィールドを設定する方法ですか？私はあなたが私に尋ねようとしていることを理解してくれることを願っています – vibetribe93

+0

すべてのユーザーをページにレンダリングさせて、それらを更新する考えはありますか？ – kimy82

正確には、私が話していた行の隠れたドロップダウンに配置する必要があります。そのため、サーバーからIDを取得してフィールドに入力するのではなく、このアプローチを選択しました。 – vibetribe93
