[解決済み】クライアントが送信したリクエストは構文的に正しくありません -Spring MVC + JDBC Template

2022-02-16 15:56:46

質問

Spring MVCの初心者です。 プロジェクトを実行中にエラーで動けなくなりました。 Error-The request sent by the client was syntactically incorrect. 私はPatientInfoというエンティティクラスを持っています。 私の jsp ページは demo1 です。 私のコントローラはPatient Controllerです。 私が実装したい機能は、データベースへの値の挿入です。 しかし、私はコントローラで私の関数(add-update2)を呼び出すことができません。

デモ1.jsp 

        <%@taglib prefix="form" uri="http://www.springframework.org/tags/form"%>

解決方法は？

問題は、Springが以下のような送信時にブラウザクライアントが送信する日付をデシリアライズする方法を知らないことだと思います。 input フィールドの 

<tr name="tstest">
    <td>Date Of Birth</td>
    <td><form:input path="dateOfBirth" name="timestamp" value=""/>
        <a href="javascript:show_calendar('document.tstest.timestamp', document.tstest.timestamp.value);"><img src="../images/cal.gif" width="16" height="16" border="0" alt="Click Here to Pick up the timestamp"></a>
    </td>
</tr>

Springはそのフィールドに入力された値をどのようにして Date オブジェクトを作成します。を登録する必要があります。 PropertyEditor を使用します。例えば、以下のように @Controller クラス 

@InitBinder
public void initBinder(WebDataBinder binder) {
    SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
    sdf.setLenient(true);
    binder.registerCustomEditor(Date.class, new CustomDateEditor(sdf, true));
}

当然ながら SimpleDateFormat を、クライアントが送信しているものに置き換えてください。

関連して、リダイレクトを送信することで302レスポンスを送信することになります 

return "redirect:/full-reg";

リクエストとモデルの属性は、1つのリクエストの間だけ有効であることを忘れないでください。ですから、あなたのクライアントがリクエストを full-reg この場合、最初に送信したフォーム入力パラメータはもう存在しません。この方法をもう一度考えてみる必要があります。
