【问题描述】：

我正在尝试将 Spring-webflow 与 Spring-MVC 结合使用。我按照 Spring 参考中提到的步骤进行操作，并且可以访问第一页，其中包含以下代码：

<%@page isELIgnored="false" %>
<html>
<head>
<title>Import</title>
</head>
<body>
    <a href="${flowExecutionUrl}&_eventId=facebook">Import facebook
        datas</a>
</body>
</html>

但是，它会将我重定向到 localhost/myAPP/&_eventId=facebook，并出现 404 错误。

这是我的 servlet 配置文件：

        <property name="flowRegistry" ref="flowRegistry"/>
        <property name="order" value="0" />

这是我的 webflow 配置文件：

<?xml version="1.0" encoding="UTF-8"?>

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <view-state id="import" view="import.jsp">
        <transition on="facebook" to="facebook" />
    </view-state>

    <end-state id="facebook" />
</flow>

我想我在 url 解析器的某个地方失败了，但我不能说在哪里。有什么想法吗？

【解决方案1】：

它会将您重定向到 *localhost/myAPP/&_eventId=faceboo* 但它应该是这样的：

localhost/myAPP/registryImport?execution=s1e1&_eventId=facebook

带有此链接的页面上浏览器显示的地址是什么？你如何开始你的流程？

【讨论】：

为了回答您的第二个问题，我先转到 myApp/import/import 开始流程。我现在无法尝试您的建议，我会尽快通知您。跨度>
