Prevent stack trace logging for custom exception in Spring Boot application
I'm using Spring Boot 2+just add this line to your application.properties:
server.error.include-stacktrace=never
Be wary of Spring Boot DevTools.
Despite NEVER being the default for server.error.include-stacktrace, if you include Spring Boot DevTools it overides to ALWAYS.
If you're interested in more detail, see this commit, which became part of Spring Boot 2.1.0+
If you don't need the stack trace you can suppress the stack trace by overriding fillInStackTrace in your exception class.
public class DuplicateFoundException extends RuntimeException { @Override public synchronized Throwable fillInStackTrace() { return this; }}When you invoke e.printStackTrace() then no stack trace will be printed.
