If it is published to WebLogic, it can be configured in Webcontent\web-inf\weblogic.xml.
The reference configuration is as follows:

ClassLoader load order when Tomcat starts
A list of the precedence orders for Tomcat class loading
1. First is the jar file under $java_home/jre/lib/ext/.
2. The Jar and class files in the environment variable CLASSPATH.
3. $CATALINA the class file under _home/common/classes.
4. $CATALINA the jar file under _home/commons/endorsed.
5. $CATALINA the jar file under _home/commons/i18n.
6. $CATALINA the jar file under _home/common/lib.
(a jar file, such as the JDBC driver, can be placed here so that you can avoid a situation where the JDBC driver is not found in Server.xml configuration of the data source.) ）
7. $CATALINA the class file under _home/server/classes.
8. $CATALINA the jar file under _home/server/lib/.
9. $CATALINA the class file under _base/shared/classes.
$CATALINA the jar file under _base/shared/lib.
11. The class file under each specific webapp/web-inf/classes.
12. jar files under their specific webapp/web-inf/lib
