Instantiate an Axon Server CommandBus client. Will connect to an Axon Server instance to submit and receive commands and command responses.

Parameters:

axonServerConnectionManager - a AxonServerConnectionManager which creates the connection to an Axon Server platform

configuration - the AxonServerConfiguration containing specifics like the client and component names used to identify the application in Axon Server among others

localSegment - a CommandBus handling the incoming commands for the local application

serializer - a Serializer used for de/serialization command requests and responses

routingStrategy - a RoutingStrategy defining where a given CommandMessage should be routed to

AxonServerCommandBus

public AxonServerCommandBus(AxonServerConnectionManager axonServerConnectionManager,
                            AxonServerConfiguration configuration,
                            org.axonframework.commandhandling.CommandBus localSegment,
                            org.axonframework.serialization.Serializer serializer,

Instantiate an Axon Server Command Bus client. Will connect to an Axon Server instance to submit and receive commands. Allows specifying a CommandPriorityCalculator to define the priority of command message among one another.

Parameters:

axonServerConnectionManager - a AxonServerConnectionManager which creates the connection to an Axon Server platform

configuration - the AxonServerConfiguration containing client and component names used to identify the application in Axon Server

localSegment - a CommandBus handling the incoming commands for the local application

serializer - a Serializer used for de/serialization command requests and responses

routingStrategy - a RoutingStrategy defining where a given CommandMessage should be routed to

priorityCalculator - a CommandPriorityCalculator calculating the request priority based on the content, and adds this priority to the request
