当我尝试使用带有spring 5的REST API时，服务器启动时出现以下错误。Maven构建正在生成战争，但当我使用Smart Tomcat运行应用程序时，我会得到以下错误。
20-Sep-2022 17:16:59.737 INFO [main] org.apache.jasper.servlet.TldScanner.scanJars At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

为了提供一些额外的上下文，作为需求的一部分，我必须使用这个RESTApi来进一步连接到SOAP服务。谢谢
编辑1：奇怪的是，我再也没有收到这个错误了。但是，当启动tomcat时，我在tomcat Localhost日志中得到以下错误：

尽管，我在控制台中，它表明服务器启动是成功的：

我在尝试访问url时遇到404错误。
SO，最初的错误是通过某种方式修复的。我再也没有看到那个错误。第二个错误(Edit 1(在我从终端启动tomcat服务器时得到了修复，并且没有使用智能tomcat，这是一个intellij插件。
