我正在运行 Tomcat 9、Java 11 并部署 Spring Boot 应用程序。
应用程序已成功部署，但我收到 404 响应。查看 Tomcat 日志，它说找不到 JAR，但如果我在 WEB-INF/lib 下找到文件 spring-messaging-5.3.29.jar，它实际上就在那里。
那么这可能是什么原因呢？
编辑：如果我重新部署应用程序，它会显示另一个 JAR spring-boot-starter-data-jpa-2.7.14.jar。我想，这里总体上有些东西被破坏了。
感谢您的回复！

最后，我通过将正确的Java版本放入
pom.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>
