我的应用程序几天前运行良好，但今天执行时出现以下错误：

我尝试过更换tomcat但没有改变，现在我不知道错误是什么。

如果类在编译期间存在但在运行时在类路径中不可用，U 将得到 NoClassDefFoundError。请检查以前在运行时可用的所有 jar 是否仍然可用。它似乎以某种方式被覆盖了。

标签： java spring tomcat

【解决方案1】：

编辑您的 pom 文件并将此类 org/apache/tomcat/util/descriptor/tld/TldParser 的 jar 文件添加到您的 pom 文件中。看这个链接：add TldParser to pom file

【解决方案2】：

这纯粹是一个依赖问题。你必须使用 dependency:tree 来弄清楚。它对我有用的方式是解决依赖问题并启用 spring boot 以调试模式 logging.level.org.springframework = debug

如果您的项目是 spring boot + tld，请关注 tomcat 依赖

为我的项目附加示例 pom。
