With Spring Boot 2.3 / Tomcat 9, you can set a timeout for ALL incoming HTTP requests to complete by installing a Tomcat StuckThreadDetectionValve.Here's the Spring configuration code you'll need (it's Kotlin): import org.apache.catalina.valves.StuckThreadDetectionValve import You have an application that works but lets suppose that the call to get all French-speaking countries is 2 seconds long and the call to get all European countries is 3 seconds long.
