java - 错误 500--内部服务器错误 java.lang.NoClassDefFoundError : javax/servlet/jsp/jSTL/core/Config

Question

我在 weblogic 服务器中部署 war 文件时遇到以下错误。我是使用 Maven 创建的。

我在 lib 中有 jSTL-1.2，在 weblogic 中也有 jSTL-1.2。但出现相同的异常。

我也尝试从 war lib 文件夹中删除 jSTL-1.2。即使得到相同的异常。

可能是什么原因？

这是我的pom

这是我的war lib文件夹

Answer 1

On Weblogic, or Websphere , or JBoss or any other EJB container 在maven中设置依赖范围对于 pom.xml 中的 servlet-api “提供”。对 jSTL 依赖项执行相同的操作。 ****它们已经作为您的应用程序服务器的一部分出现。绝对没有理由将 servlet 打包到您的 jar 中。****

确保它们不存在于您的 war lib 文件夹中。如果它们仍然存在，则需要检查传递依赖性。您可以通过从命令行执行“mvn dependency:tree” 来找到它们。

在 Tomcat 或 Jetty 或其他 servlet 容器 上。 jSTL 不是作为提供的库提供的，因此您需要将它部署为 WEB-INF/lib 中的 WAR 存档的一部分。这就是说，如果您使用 Maven，则依赖范围应设置为“compile”。
