Question

我正在尝试将忘记密码路径添加到现有视图中。我在我的webflow中创建了一个新的视图，动作，模型bean和一些状态。我没有看到视图，而是继续收到错误java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'forgotPassword' available as request attribute。我知道bean存在，它应该是可见的。我认为我正确设置了网络流，但我不是百分百肯定。有谁知道我可能做错了什么？

casLoginView.jsp：

<a href="/cas/login?execution=${flowExecutionKey}&_eventId=forgotPassword">Forgot Password</a>

登录-webflow.xml：

<var name="credentials" class="org.jasig.cas.authentication.principal.UsernamePasswordCredentials" />
<var name="forgotPasswordBean" class="com.mycompany.authentication.ForgotPasswordBean" />

<view-state id="viewLoginForm" view="casLoginView" model="credentials">
    <binder>
        <binding property="username" />
        <binding property="password" />
    </binder>
    <on-entry>
        <set name="viewScope.commandName" value="'credentials'" />
    </on-entry>
    <transition on="submit" bind="true" validate="true" to="realSubmit">
        <evaluate expression="authenticationViaFormAction.doBind(flowRequestContext, flowScope.credentials)" />
    </transition>
    <transition on="forgotPassword" bind="false" validate="false" to="forgotPasswordView"/>
</view-state>

<view-state id="forgotPasswordView" view="myForgotPasswordView.jsp" model="forgotPasswordBean">
     <binder>
        <binding property="username" required="true"/>
    </binder>
    <transition on="submit" to="forgotPassword"/>
</view-state>

<action-state id="forgotPassword">
    <evaluate expression="forgotPasswordAction.submit(flowScope.forgotPasswordBean)" />
    <transition on="success" to="newPasswordSentView"/>
    <transition on="forbidden" to="forgotPasswordForbiddenView"/>
    <transition on="error" to="forgotPasswordView"/>
</action-state>

<end-state id="newPasswordSentView" view="myNewPasswordSentView" />
<end-state id="forgotPasswordForbiddenView" view="forgotPasswordForbiddenView" />

Answer 1

您的<form:form ... >标记应引用正确的bean。您的配置提到forgotPasswordBean而不是forgotPassword。

您的表单对象应引用正确的bean

<form:form modelAttribute="forgotPasswordBean" ... >

或者您应该在webflow配置中重命名bean（包括对它的所有引用）。

<var name="forgotPassword" class="com.mycompany.authentication.ForgotPasswordBean" />

Webflow绑定失败
