You can use the `@CookieValue` annotation to bind the value of an HTTP cookie to a method argument
in a controller.

The following example shows a request with a cookie:

[literal,subs="verbatim,quotes"]
----
JSESSIONID=415A4AC178C59DACE0B2C9CA727CDD84
----

The following code sample demonstrates how to get the cookie value:

[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes"]
----
	@GetMapping("/demo")
	public void handle(@CookieValue("JSESSIONID") String cookie) { // <1>
		//...
	}
----
<1> Get the cookie value.

Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes"]
----
	@GetMapping("/demo")
	fun handle(@CookieValue("JSESSIONID") cookie: String) { // <1>
		//...
	}
----
<1> Get the cookie value.
======


Type conversion is applied automatically if the target method parameter type is not
`String`. See xref:web/webflux/controller/ann-methods/typeconversion.adoc[Type Conversion].
