Class SpringCloudHttpBackupCommandRouter

java.lang.Object

org.axonframework.extensions.springcloud.commandhandling.SpringCloudCommandRouter

org.axonframework.extensions.springcloud.commandhandling.SpringCloudHttpBackupCommandRouter

All Implemented Interfaces:

org.axonframework.commandhandling.distributed.CommandRouter

Deprecated.

in favor of using the regular SpringCloudCommandRouter with the RestCapabilityDiscoveryMode

@Deprecated
 @RestController
 @RequestMapping(value="${axon.distributed.spring-cloud.fallback-url:/message-routing-information}")
public class SpringCloudHttpBackupCommandRouter
extends SpringCloudCommandRouter

Implementation of the SpringCloudCommandRouter which has a backup mechanism to provide Message Routing Information for other nodes and to retrieve Message Routing Information from other Axon nodes.

It is annotated with the RestController and contains the GetMapping annotated getLocalMessageRoutingInformation() function to have a queryable place to retrieve this node its Message Routing Information. The default endpoint for this is "/message-routing-information". To configure this endpoint the "axon.distributed.spring-cloud.fallback-url" application property should be adjusted.

For retrieving the Message Routing Information from other Axon nodes, it uses a RestTemplate to request Message Routing Information through an override of the SpringCloudHttpBackupCommandRouter#getMessageRoutingInformation(ServiceInstance) function.

Constructor Detail

SpringCloudHttpBackupCommandRouter

protected SpringCloudHttpBackupCommandRouter(SpringCloudHttpBackupCommandRouter.Builder builder)

Deprecated.

Instantiate a SpringCloudHttpBackupCommandRouter based on the fields contained in the SpringCloudHttpBackupCommandRouter.Builder.

Will assert that the RestTemplate is not null and that the messageRoutingInformationEndpoint is not null and empty. This assertion will throw an AxonConfigurationException if either of them asserts to true. All asserts performed by the SpringCloudCommandRouter.Builder are also taken into account with identical consequences.

Parameters:

builder - the SpringCloudHttpBackupCommandRouter.Builder used to instantiate a SpringCloudHttpBackupCommandRouter instance

Method Detail

builder

public static SpringCloudHttpBackupCommandRouter.Builder builder()

Deprecated.

Instantiate a Builder to be able to create a SpringCloudHttpBackupCommandRouter.

The serviceInstanceFilter is defaulted to a Predicate which always returns true, the ConsistentHashChangeListener to a no-op solution and the messageRoutingInformationEndpoint to "/message-routing-information". The DiscoveryClient, localServiceInstance of type Registration, the RoutingStrategy, RestTemplate and messageRoutingInformationEndpoint are hard requirements and as such should be provided.

Returns:

a Builder to be able to create a SpringCloudHttpBackupCommandRouter

getLocalMessageRoutingInformation

@Deprecated
 @GetMapping
public MessageRoutingInformation getLocalMessageRoutingInformation()

Deprecated. in favor of the RestCapabilityDiscoveryMode.getLocalMemberCapabilities() method

Get the local MessageRoutingInformation, thus the MessageRoutingInformation of the node this CommandRouter is a part of. Can either be called directly or through a GET operation on the specified messageRoutingInformationEndpoint of this node.

Returns:

the MessageRoutingInformation if the node this CommandRouter implementation is part of
