java - Spring MVC 3 JSF 2 与 Maven

Question

我正在尝试在我的 spring3 应用程序中使用 JSF 复合组件。

出现以下错误:

    WARNING: Unable to load class [javax.servlet.jsp.el.ImplicitObjectELResolver$EnumeratedMap] to check against the @HandlesTypes annotation of one or more ServletContentInitializers.

这是我的项目结构:

我刚刚从下面的链接复制了代码......可以帮助我为什么我会收到此错误......

我还在 faces-config 中收到警告，如下链接所示:

Class org.springframework.web.jsf.el.SpringBeanFacesELResolver must extend the type javax.el.ELResolver

如果您提供了 POM.xml，这将有助于解决问题，因为异常清楚地表明它无法找到必要的类

java.lang.ClassNotFoundException: javax.servlet.jsp.el.ImplicitObjectELResolver 

检查 pom.xml 中是否有 javax.servlet.jsp-api 和 javax.el-api 的依赖项，或添加以下 Maven 依赖项

<dependency>
        <groupId>javax.servlet.jsp</groupId>
        <artifactId>javax.servlet.jsp-api</artifactId>
        <version>2.2.1</version>
        <scope>provided</scope>
 </dependency>

 <dependency>
       <groupId>javax.el</groupId>
       <artifactId>javax.el-api</artifactId>
       <version>2.2.2</version>
       <scope>provided</scope>
 </dependency>
