The Spring Framework supports various Kotlin constructs, such as instantiating Kotlin classes
|
|
through primary constructors, immutable classes data binding, and function optional parameters
|
|
with default values.
|
|
|
|
Kotlin parameter names are recognized through a dedicated `KotlinReflectionParameterNameDiscoverer`,
|
|
which allows finding interface method parameter names without requiring the Java 8 `-parameters`
|
|
compiler flag to be enabled during compilation. (For completeness, we nevertheless recommend
|
|
running the Kotlin compiler with its `-java-parameters` flag for standard Java parameter exposure.)
|
|
|
|
You can declare configuration classes as
|
|
{kotlin-docs}/nested-classes.html[top level or nested but not inner],
|
|
since the latter requires a reference to the outer class.
