我在运行代码时遇到问题。每次我运行代码时，服务器都会抛出此错误，我检查了我添加的每个 jar 是否正确，还检查了jdk和jre路径，但我无法解决问题。

详细检查异常，尤其是"原因"部分。它绝对可以帮助您找到原因。
另外，如果您使用的是 maven，请检查 maven 依赖树中是否有任何不同版本的 jar 文件，尤其是servlet jar。
如果在 Windows 上，将 "-verbose 添加到 tomcat "bin/wrapper.conf" 中的JVM_OPTS列表中wrapper.java.additional.11="-verbose"。这将帮助您找到根本原因
我有同样的问题，比如，

我已经通过从 apache/conf/Catalina/localhost 中删除除 web 之外的所有 xml 文件来解决它.xml并且它工作正常。
