Enum LivenessState

java.lang.Enum<LivenessState>

org.springframework.boot.availability.LivenessState

All Implemented Interfaces:

Serializable, Comparable<LivenessState>, Constable, AvailabilityState

public enum LivenessState
extends Enum<LivenessState>
implements AvailabilityState

"Liveness" state of the application.

An application is considered live when it's running with a correct internal state. "Liveness" failure means that the internal state of the application is broken and we cannot recover from it. As a result, the platform should restart the application.

2.3.0
