Interface HealthAggregator

All Known Implementing Classes:

AbstractHealthAggregator, OrderedHealthAggregator

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface HealthAggregator

Strategy interface used to aggregate Health instances into a final one.

This is especially useful to combine subsystem states expressed through Health.getStatus() into one state for the entire system. The default implementation OrderedHealthAggregator sorts Status instances based on a priority list.

It is possible to add more complex Status types to the system. In that case either the OrderedHealthAggregator needs to be properly configured or users need to register a custom HealthAggregator as bean.
