java.lang.ClassNotFoundException : com. 太阳.faces.config.ConfigureListener

标签 java spring-mvc listener classnotfoundexception jspx

我正在学习 Java、Spring MVC 和 Eclipse。我现在正在读一本书，并试图让第一个 Spring MVC 示例运行。当我从 Eclipse 运行它时，出现此错误:

我不知道去哪里寻找项目中的错误，有什么建议吗？

最佳答案

我有同样的错误，但找到了我们问题的解决方案，我猜你正在使用 maven 和 tomcat 7。我在 Glassfish 4 中部署并且工作完美，所以对我来说它看起来很陌生。

解决方案:

修复您的 pom.xml 以在 Tomcat 7 中工作。

  1. javaee-api 应该有 scope: provided。
  2. 将 jSTL-api 依赖项 1.2 添加到您的 pom.xml，范围:编译。

示例:

<!-- Tomcat 7 Deploy -->
<dependency>
    <groupId>javax.servlet.jsp.jstl</groupId>
    <artifactId>jstl-api</artifactId>
    <version>1.2</version>
    <scope>provided</scope>
</dependency>
<!-- JavaEE -->
<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
    <scope>compile</scope>
</dependency>

解释:

您正在添加 JEE 6:

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
    <scope>compile</scope>
</dependency>

你得到了错误:

SEVERE: Error configuring application listener of class com.sun.faces.config.ConfigureListener
java.lang.ClassNotFoundException: com.sun.faces.config.ConfigureListener
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1702)
...

以某种方式将 javaee-api.jar 添加到 WEB-INF/lib 会尝试搜索或加载 jsf 配置文件，即使我们没有使用它。然后将范围更改为提供，我开始收到缺少 JSTL 库的新错误。

所以我结束了添加 jSTL-api 库。
