@CookieValue

See equivalent in the Reactive stack

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

Consider a request with the following cookie:

JSESSIONID=415A4AC178C59DACE0B2C9CA727CDD84

The following example shows how to get the cookie value:

Java

@GetMapping("/demo")
public void handle(@CookieValue("JSESSIONID") String cookie) { (1)
	//...
}

1. Get the value of the JSESSIONID cookie.

Kotlin

@GetMapping("/demo")
fun handle(@CookieValue("JSESSIONID") cookie: String) { // (1)
	//...
}

1. Get the value of the JSESSIONID cookie.

If the target method parameter type is not String, type conversion is applied automatically. See Type Conversion.
