英文:
Tomcat 9 NoSuchFileException in WEB-INF/lib but the file is present
问题
我正在运行Tomcat 9，Java 11，并部署了一个Spring Boot应用程序。
该应用程序已成功部署，但我收到了404响应。查看Tomcat日志，它说找不到一个JAR文件，但如果我定位到WEB-INF/lib目录下的文件spring-messaging-5.3.29.jar，实际上是存在的。
那么可能的原因是什么？
编辑：如果我重新部署应用程序，会出现另一个JAR文件spring-boot-starter-data-jpa-2.7.14.jar。我猜，总体上出现了一些问题。
感谢您的回复！
英文:
I'm running Tomcat 9, Java 11 and deploy a Spring Boot Application.
The application was successfully deployed but I'm getting a 404 response. Looking in the Tomcat logs, it says that a JAR could not be found but if I locate the file spring-messaging-5.3.29.jar under WEB-INF/lib, it's actually there.
So what can be the reason?
Edit: If I redeploy the application, it shows up another JAR spring-boot-starter-data-jpa-2.7.14.jar. I guess, something in general is broken here.
Thanks for your response!

最后，我通过在 pom.xml 中放入正确的Java版本解决了这个问题：
<!-- language: xml -->
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.release>11</maven.compiler.release> <!-- Java版本 -->
<tomcat.version>9.0.31</tomcat.version>
</properties>
英文:
Finally, I solved the issue by putting the correct Java version in the pom.xml:
<!-- language: xml -->
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.release>11</maven.compiler.release> <!-- Java version -->
<tomcat.version>9.0.31</tomcat.version>
</properties>
