URI Paths

The value of the @Controller annotation is a RFC-6570 URI template you can therefore embed URI variables within the path using the syntax defined by the URI template specification.

The actual implementation is handled by the UriMatchTemplate class, which extends UriTemplate.

You can use this class explicitly within your application to build URIs. For example:

Using a UriTemplate

        UriMatchTemplate template = UriMatchTemplate.of("/hello/{name}");
        assertTrue(template.match("/hello/John").isPresent()); (1)
        assertEquals("/hello/John", template.expand(  (2)
                Collections.singletonMap("name", "John")
        ));

Using a UriTemplate

        given:
        UriMatchTemplate template = UriMatchTemplate.of("/hello/{name}")
        expect:
        template.match("/hello/John").isPresent() (1)
        template.expand(["name": "John"]) == "/hello/John" (2)

Using a UriTemplate

        val template = UriMatchTemplate.of("/hello/{name}")
        assertTrue(template.match("/hello/John").isPresent) (1)
        assertEquals("/hello/John", template.expand(mapOf("name" to "John")))  (2)

If you have a requirement to build paths to include in your responses you can use UriTemplate to do so.
