Package org.springframework.core

Class DefaultParameterNameDiscoverer

java.lang.Object

org.springframework.core.PrioritizedParameterNameDiscoverer

org.springframework.core.DefaultParameterNameDiscoverer

All Implemented Interfaces:

ParameterNameDiscoverer

public class DefaultParameterNameDiscoverer
extends PrioritizedParameterNameDiscoverer

Default implementation of the ParameterNameDiscoverer strategy interface, using the Java 8 standard reflection mechanism (if available), and falling back to the ASM-based LocalVariableTableParameterNameDiscoverer for checking debug information in the class file.

If a Kotlin reflection implementation is present, KotlinReflectionParameterNameDiscoverer is added first in the list and used for Kotlin classes and interfaces. When compiling or running as a GraalVM native image, the KotlinReflectionParameterNameDiscoverer is not used.

Further discoverers may be added through PrioritizedParameterNameDiscoverer.addDiscoverer(ParameterNameDiscoverer).

Since:

4.0
