Using Map<String, String> with @PathVariable

Is that map populated with all path variable names and values?

@PathVariable is a Spring annotation which indicates that a method parameter should be bound to a URI template variable. If the method parameter is Map then the map is populated with all path variable names and values.

It has the following optional elements:

• name — name of the path variable to bind to
• required — tells whether the path variable is required
• value — alias for name

@GetMapping(value = "/book/{author}/{title}")
public void process3(@PathVariable Map<String, String> vals) {

   logger.info("{}: {}", vals.get("author"), vals.get("title"));

}
