Question

我正在升级我们的网络应用程序以使用Wicket 7（使用6.19）。

第一页是登录屏幕，但由于某种原因，表单的onSubmit()方法未被调用，因此单击提交按钮时，我只是重新显示登录页面。

我咨询了Wicket 7 migration guide，但未提及此领域的任何具体变化。

这是一个非常简单的案例，正如您所看到的，它是一个包含用户名和密码字段的简单表单

    <form wicket:id="loginform" id="loginform" >
        <table style="display: table; border: 0px; margin: auto;">
            <tr style="display: table-row;">
                <td class="login" colspan="2"><span wicket:id="feedback">Feedback</span></td>
            </tr>
            <tr style="display: table-row;">
                <td class="login">
                    <label for="username"><wicket:message key="username">Username</wicket:message>:&nbsp;</label>
                </td>
                <td class="login">
                    <input wicket:id="username" id="username" type="text" name="user" value="" size="30" maxlength="50"/>
                </td>
            </tr>
            <tr style="display: table-row;">
                <td class="login">
                    <label for="password"><wicket:message key="password">Password</wicket:message>:&nbsp;</label>
                </td>
                <td class="login">
                    <input wicket:id="password" id="password" type="password" name="pswd" value="" size="30" maxlength="16"/>
                </td>
            </tr>
            <tr style="display: table-row;">
                <td class="login">&nbsp;</td>
                <td class="login"><input class="btn" type="submit" name="Login" value="Login" wicket:message="title:loginButtonTitle"/></td>
            </tr>
        </table>
    </form>

这是设置页面组件的Java代码 -

public class Login extends UnSecurePageTemplate {
private static final long serialVersionUID = -7202246935258483555L;

@SpringBean private IBrandingService brandingService;
@SpringBean private IRemonService remonService;
@SpringBean private IUserAdminService userAdminService ;

private static final Logger logger  = LoggerFactory.getLogger( Login.class);

public Login()  {
    this(new PageParameters());
}

public Login(PageParameters pageParameters) {
    super(pageParameters);


    BrandingThemeProperties properties = brandingService.getBrandingThemeProperties();

    String welcomeLabel = properties.getProperty("welcome-label");

    add(new Label("welcome", welcomeLabel));
    add(new Label("loginHeader", getStringFromPropertiesFile("loginInstruction", this)));

    LoginForm form = new LoginForm("loginform", new SimpleUser(), pageParameters);
    form.add(new FeedbackPanel("feedback"));

    add(form);
}

这是登录表单（login()方法验证用户并返回另一页） -

public final class LoginForm extends Form<SimpleUser>
{
    PageParameters pageParameters;

    public LoginForm(String id, SimpleUser simpleUser, PageParameters pageParameters)
    {
        super(id, new CompoundPropertyModel<SimpleUser>(simpleUser));
        this.pageParameters = pageParameters;

        add(new TextField<String>("username").setRequired(true).add(StringValidator.maximumLength(50)));
        add(new PasswordTextField("password").setResetPassword(true).add(StringValidator.maximumLength(50)));

   }


    /**
     * Called upon form submit. Attempts to authenticate the user.
     */
    protected void onSubmit()
    {
        SimpleUser user = getModel().getObject();
        String username = user.getUsername();
        String password = user.getPassword();

        login(username, password, pageParameters);
    }
}

我也尝试使用提交按钮，但其onSubmit()也未被调用。

升级到Wicket 7后，不会调用onSubmit（）表单
