Spring 3.1 MVC web应用配置示例中的安全性和Webflow？

Question

我正在尝试将 webflow 和安全配置添加到可运行的 Spring 3.1 MVC Web 应用程序中。

我摆脱了application-context.xml 文件和ContextLoaderListener，并将AnnotationConfigWebApplicationContext 与@EnableWebMvc @Configuration 注释类一起使用。

然而，当我关注 webflow 和安全文档时，似乎需要 application-context.xml 文件和 ContextLoaderListener。后者似乎与AnnotationConfigWebApplicationContext 产生冲突。

谁能提供一个简单但完整的 Spring 3.1 MVC Web 应用程序配置，带有 webflow 和启用安全性的示例？我正在寻找一个web.xml 示例文件，以及任何其他必需的文件。

如果有人可以在线下载完整的示例应用程序，那就更好了。

在部署到 Tomcat 7 时以下工作：

web.xml

网络配置

@EnableWebMvc
@ImportResource({ "/WEB-INF/spring-security.xml", "/WEB-INF/spring-webflow.xml"})
@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {

    // ...

}

警告： 使用 @Import(SomeConfig.class) 不再起作用。它会导致初始化问题。解决方法是将SomeConfig.class 的内容移动到WebConfig.class 本身。

添加适当的maven依赖很重要，否则Tomcat会导致404 Resource not found错误消息：
