Answer by Koraktor for What's the best way to get the current URL in Spring MVC?

Instead of using RequestContextHolder directly, you can also use ServletUriComponentsBuilder and its static methods:

• ServletUriComponentsBuilder.fromCurrentContextPath()
• ServletUriComponentsBuilder.fromCurrentServletMapping()
• ServletUriComponentsBuilder.fromCurrentRequestUri()
• ServletUriComponentsBuilder.fromCurrentRequest()

They use RequestContextHolder under the hood, but provide additional flexibility to build new URLs using the capabilities of UriComponentsBuilder.

Example:

ServletUriComponentsBuilder builder = ServletUriComponentsBuilder.fromCurrentRequestUri();builder.scheme("https");builder.replaceQueryParam("someBoolean", false);URI newUri = builder.build().toUri();
