In a standalone tomcat I can create a context.xml with:
<Context>
...
<JarScanner scanManifest="false"/>
...
</Context>
How can I disable the JarScanner for manifest files (https://tomcat.apache.org/tomcat-8.0-doc/config/jar-scanner.html) in a java configuration class using Spring Boot.

If we want to exclude tomcat from spring boot, we don't need to do much, we just need to add one additional block(<exclusions>) to the Spring Boot dependency. <exclusions> tag is used to make us sure that given server/artifactId is being removed at the time of build.
On startup, Tomcat recursively scans the WEB-INF directories for TLD (Tag Library Descriptor) files. As a result, if a webapp has a lot of files under that directory, it slows down the startup process.
Anyway, the tomcat-embed-jasper is marked as provided , so indicates that you expect the JDK or a container to provide the dependency at runtime. This scope is only available on the compilation and test classpath, and is not transitive.
Overview. Spring Boot ships with an Embedded Tomcat Server. When we run a Spring Boot Application, the embedded tomcat server is started and the application is launched inside the server. The Embedded tomcat server has a set of default configurations, which makes them ready to use.
This is controllable via a property now:
# Comma-separated list of additional patterns that match jars to ignore for TLD scanning.
server.tomcat.additional-tld-skip-patterns=*.jar
via AFTER upgrade from Spring boot 1.2 to 1.5.2, FileNotFoundException during Tomcat 8.5 Startup
