我正在从eclipse的外部tomcat 6运行我的JSF 2应用程序 ，一切正常，但是当我尝试使用maven tomcat插件时

mvn tomcat:run

我在其中一页上遇到以下异常：

java.lang.NoSuchMethodError: javax.el.E​​LResolver.invoke(Ljavax/el/ELContext;Ljava/lang/Object;Ljava/lang/Object;[Ljava/lang/Class;[Ljava/lang/Object;)Ljava/lang /目的;

该方法是在EL 2.2中引入的。此异常表明您的 webapp/WEB-INF/lib被旧 EL 版本的库污染。Tomcat 7.0 本身已经随 EL 2.2 一起提供，但其中任何特定于容器的库都/WEB-INF/lib将在类加载中获得优先权。也许您声明了一个未提供的 EL 2.1 依赖项，pom.xml而不是提供的 EL 2.2 依赖项。

如果您同时使用Tomcat6和Maven，请从您的bin文件夹中删除el-api.jar，因为maven已经将它添加到您的项目中。在pom.xml中，请务必添加与el-api库相关的版本标签。我尝试了这个解决方案，它现在可以工作了！

    <dependency>
        <groupId>javax.el</groupId>
        <artifactId>el-api</artifactId>
        <version>2.2</version>
    </dependency>
