Encoded slash (/) with Spring RequestMapping path param gives HTTP 400

Question

This is not a duplicate referenced question, because it is Spring specific. Whoever added that (3 years after the fact!) didn\'t bother to read the question or comment

Answer 1

The following resolved the BACK_SLASH issue:

public static void main(String[] args) throws Exception {
  System.setProperty("org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH", "true");
  SpringApplication.run(Application.class, args);
}

But, same functionality could be done via application.yml.

org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH: true

This setting doesn't work. I did not find a way for that, and still looking at it.
