Maybe a tiny bug?

Sorry. I don't speak Japanese.

AntPthMatcher with VERSIONED_PATH_PATTERN is very very smart, sir!

But VERSIONED_PATH_PATTERN cannot be a fixed value.

Please check my controller below:

import jakarta.servlet.http.HttpServletRequest;
import org.springframework.util.AntPathMatcher;
import org.springframework.util.PathMatcher;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.Map;
import java.util.Optional;

@RestController
@RequestMapping("/{version}")
public class TestController {

    private static final PathMatcher PATH_MATCHER = new AntPathMatcher();

    private static final String VERSIONED_PATH_PATTERN = "/{version:.*}/**";

    @GetMapping("/test")
    public Map<String, String> test(@PathVariable("version") String version, HttpServletRequest request) {
        return Map.of(
                "version-from-path-variable", version,
                "version-from-path-matcher", getRequestApiVersion(request)
        );
    }

    private static String getRequestApiVersion(HttpServletRequest request) {
        return Optional
                .ofNullable(PATH_MATCHER.extractUriTemplateVariables(VERSIONED_PATH_PATTERN, request.getRequestURI()))
                .map(map -> map.get("version"))
                .orElse(null);
    }

}

if the spring-boot configuration property (in classpath:application.yaml)

like the

server:
  servlet:
    context-path: "/"   # default value

The code is fine.

but if you change the configuration to your name ("/uich")

the version string will be parsed as "uich".

Thank you all the same, your post in QITA.COM saved my hours!
