Spring Webflow 2.3.0 示例无法启动...不知道如何修复

Question

我目前正在评估 Spring（重点是 WebFlow）以用于未来的项目。在阅读了大量文档和文章（其中大部分没有多大帮助）后，我下载了 Spring WebFlow 的当前版本（撰写本文时为 2.3.0）并尝试运行示例。除了可解决但令人沮丧的依赖项和类路径问题之外，我还遇到了与示例一起分发的配置文件的第一个障碍。首先，booking-mvc-sample 的 webflow-config.xml 甚至无效。

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

           http://www.springframework.org/schema/webflow-config/spring-webflow-config.xsd">

    <!-- The registry of executable flow definitions -->
    <webflow:flow-registry id="flowRegistry" flow-builder-services="flowBuilderServices" base-path="/WEB-INF">

    <!-- Configures Web Flow to use Tiles to create views for rendering; Tiles allows for applying consistent layouts to your views -->
    <bean id="mvcViewFactoryCreator" class="org.springframework.webflow.mvc.builder.MvcViewFactoryCreator">

        <property name="useSpringBeanBinding" value="true" />

    <bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>

</beans>

• cvc-complex-type.2.4.c：匹配通配符严格，但找不到元素“webflow:flow-executor”的声明。
• cvc-complex-type.2.4.c：匹配通配符严格，但找不到元素“webflow:flow-registry”的声明。
• cvc-complex-type.2.4.c：匹配通配符严格，但找不到元素“webflow:flow-builder-services”的声明。

更改 http://www.springframework.org/schema/webflow- config/spring-webflow-config.xsd 到 http://www.springframework.org/schema/webflow-config/spring-webflow-config-2.3.xsd 从 Eclipse 中删除验证错误，但 SAXParser 在启动时仍然抱怨。

有什么办法解决吗？有人可以帮我解决一个工作配置或指向一个工作教程（如果是示例错误，则为正确的教程；如果我做错了，则为向我展示如何正确设置 SWF 的教程）？

现在，我距离将 SWF 从我们的可能框架列表中剔除为“不是开箱即用”不远了——看看 Spring 的用户群和流行程度，这在某种程度上很难相信。

多谢。
