The following URL used to return 200 with Spring Boot 2.5

http://localhost:8080//actuator/health

After upgrading to 2.6 it no longer works and returns 404 Not Found

I spotted the error because some of the project's integration tests were failing (requests returned 404). Then I noticed the double slash, and after removing it, the issue was fixed.

I just want to understand which feature causes this new behavior?

I went through the 2.6 release notes several times, but nothing rings a bell.

Thanks in advance!

1. Are you able to access actuator endpoint with single slash? like http://localhost:8080/actuator/health

2. If yes, then did you configure the spring security for your application? There is a configuration you can define where your application will allow consecutive slashes in url.

   @Bean
   HttpFirewall httpFirewall() {
       StrictHttpFirewall firewall = new StrictHttpFirewall();
       firewall.setAllowUrlEncodedDoubleSlash(true);
       return firewall;
   }
