这是怎么引起的，我该如何解决?
How is this caused and how can I solve it?
推荐答案
C:UsersIng.Girbson BIJOUDocumentsNetBeansProjectsapache-tomcat-10.0.4-windows-x64apache-tomcat-10.0.4confCatalinalocalhost虚拟商店.xml
C:UsersIng.Girbson BIJOUDocumentsNetBeansProjectsapache-tomcat-10.0.4-windows-x64apache-tomcat-10.0.4confCatalinalocalhostVirtualStore.xml
因此，您使用的是基于 Servlet API 5.0 版的 Tomcat 10.x，而后者又是 Jakarta EE 9 版的一部分.
You're thus using Tomcat 10.x which is based off Servlet API version 5.0 which in turn is part of Jakarta EE version 9.
java.lang.NoClassDefFoundError: javax/servlet/ServletRequestListener
这是出乎意料的.javax.* 包已重命名为 jakarta.* 包自 Jakarta EE 版本 9 起.这意味着部署的 Web 应用程序实际上与 Jakarta EE 版本 9 不兼容. 部署的 Web 应用程序很可能是为旧版 JEE 开发的，其中 javax.* 包仍在使用.
This is unexpected. The javax.* package has been renamed to jakarta.* package since Jakarta EE version 9. This thus means that the deployed web application is actually not compatible with Jakarta EE version 9. The deployed web application is most likely developed for an older JEE version where the javax.* package is still used.
所以，总而言之，目标 JEE 版本不匹配，这给您带来了麻烦.您有 2 个选择:
So, summarized, the targeted JEE versions don't match up and it's causing trouble for you. You have 2 options:
将 Tomcat 降级到 9.x 版.这是仍然使用
javax.*包的最新可用版本.
或者，将部署的 Web 应用程序升级到目标 Jakarta EE 9.IE.调整项目的依赖项(例如 pom.xml)以引用基于 JEE 9+ 的版本，并在项目范围内执行 Find &将 javax.* 替换为 jakarta.*(当然除了 javax.naming.* 和 javax.xml.* 和其他一些，但 Java 编译器会很快为您指出它们).
Or, upgrade the deployed web application to target Jakarta EE 9 instead. I.e. adjust the project's dependencies (e.g. pom.xml) to reference JEE 9+ based versions instead, and perform a project-wide Find & Replace of javax.* to jakarta.* (of course except for javax.naming.* and javax.xml.* and probably a few others, but the Java compiler will quickly point out them for you).
另见:
- Apache Tomcat - 版本
- Tomcat 9 将 servlet 转换为 javax.servlet.Servlet 而不是 jakarta.servlet.http.HttpServlet(此答案包含 Tomcat 10+、Tomcat 9 正确
pom.xml声明的完整示例-、JEE 9+ 和 JEE 8-). - Apache Tomcat - Versions
- Tomcat 9 casting servlets to javax.servlet.Servlet instead of jakarta.servlet.http.HttpServlet (this answer contains complete examples of proper
pom.xmldeclarations for Tomcat 10+, Tomcat 9-, JEE 9+ and JEE 8-).
