【问题描述】：

我正在尝试部署我的第一个 Spring webflow 应用程序。但是，我被困了 3 天，出现以下错误：

org.springframework.beans.factory.parsing.BeanDefinitionParsingException：配置问题：

我已经阅读了许多文章和论坛，但找不到任何解决方案。

以下是我在 pom.xml 中添加的依赖项：

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>$spring.version</version>

下面是类路径文件，显示了我的类路径中的 jar 文件

请帮忙。

【参考方案1】：

我已经解决了这个问题。我指的是 mvc 配置文件中的 flow xml 而不是 webflow 配置。

【参考方案2】：

我遇到了这个问题。对我来说，问题出在链接到流定义文件的 web.xml 中，如下所示（这是不正确的）：

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/dispatcher-servlet.xml
        /WEB-INF/myFlow.xml
    </param-value>
</context-param>

应该是这样的（这是正确的）：

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/dispatcher-servlet.xml
    </param-value>
</context-param>

我希望这对某人有所帮助，我已经倒转了 4 个小时。
