Prevent stack trace logging for custom exception in Spring Boot application

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+

Call overloaded super constructor to avoid showing the stacktrace in response.

public class ProductCustomException extends Exception{
    
    private static final long serialVersionUID = -291211739734090347L;

    public ProductCustomException(String message) {
        super(message,null,false,false);
    }

}

Super loaded Constructor from Exception Class

 protected Exception(String message, Throwable cause,
                        boolean enableSuppression,
                        boolean writableStackTrace) {
        super(message, cause, enableSuppression, writableStackTrace);
    }
    
}

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.

I'm using Spring Boot 2+ just add this line to your application.properties:

server.error.include-stacktrace=never
