我不知道为什么它停止工作，但我不断得到的完整错误是这样的：

原因：类 'org.springframework.web.jsf.el.SpringBeanFacesELResolver' 缺失 运行时依赖项：java.lang.NoClassDefFoundError： javax/el/ELResolver

我已经尝试了许多不同的pom配置，但没有什么可以消除该错误。请协助

Answer 1

我发现问题是Tomcat 8(v8.0.38(。我切换到Tomcat 7并修改了我的Pom.xml。我还修改了我的facelet版本版本 (从 faces-config.xml 中的 2.2 到 2.1(和部署描述符版本从 3.1 到 2.5。最后，我还将 Java 版本从 1.8 更改为 1.7 - 尽管 Web 应用程序是基于 java 1.6 编译的。下面是新 Pom .xml 的示例。它可能仍然存在错误，因为我一直在尝试我在网上找到的许多建议，但它有效：
