RoutingStrategyimplementations. Could for example be used as fallback solutions when another
RoutingStrategyis unable to resolve the routing key.
|Enum Constant and Description|
Policy that indicates a random key is to be returned when no Routing Key can be found for a Command Message.

public static final UnresolvedRoutingKeyPolicy ERROR
RoutingStrategywhich always throws a
CommandDispatchExceptionregardless of the
CommandMessagereceived. Only feasible as a fallback solution which should straight out fail if the intended policy is unable to resolve a routing key.
Note that when the routing key is based on static content in the
CommandMessage, the exception raised
should extend from
AxonNonTransientException to indicate that retries do not
have a chance to succeed.
public static final UnresolvedRoutingKeyPolicy RANDOM_KEY
Although not required to be fully random, implementations are required to return a different key for each incoming command. Multiple invocations for the same command message may return the same value, but are not required to do so.
