tomcat - 在 spring boot 嵌入的 tomcat 中禁用 Jar Scan 的 scanManifest

Question

我在日志中收到一些警告，如下所示:

在独立的 tomcat 中，我可以创建一个 context.xml :

<Context>
  ...
  <JarScanner scanManifest="false"/>
  ...
</Context>

如何使用 Spring Boot 在 java 配置类中禁用 list 文件 ( https://tomcat.apache.org/tomcat-8.0-doc/config/jar-scanner.html) 的 JarScanner。

Answer 1

现在可以通过属性控制:

# Comma-separated list of additional patterns that match jars to ignore for TLD scanning.    
server.tomcat.additional-tld-skip-patterns=*.jar

通过AFTER upgrade from Spring boot 1.2 to 1.5.2, FileNotFoundException during Tomcat 8.5 Startup
