Spring Boot Auto-Configuration

The starter supports 7 options, which are listed below.

Name	Description	Default	Type
camel.lra.allowed-coordinator-urls	Comma-separated URLs, including the context path, of further LRA coordinators whose LRAs may be joined, completed or compensated. By default, only an LRA hosted by the configured coordinator is accepted. Use it when participants reach the same coordinator under different URLs, for example with different host names.		String
camel.lra.callback-secret	Secret used to sign the participant callback URLs that are enlisted with the LRA coordinator, and to verify them when the coordinator calls back. When set, a compensation or completion callback with a missing or invalid signature is rejected with HTTP 403. All the instances of a participant must use the same secret.		String
camel.lra.coordinator-context-path	The context path of the LRA coordinator service		String
camel.lra.coordinator-url	The base URL of the LRA coordinator service (e.g. http://lra-host:8080)		String
camel.lra.enabled	Global option to enable/disable component auto-configuration, default is true.	true	Boolean
camel.lra.local-participant-context-path	The context path of the local participant callback services		String
camel.lra.local-participant-url	The local URL where the coordinator should send callbacks to (e.g. http://my-host-name:8080)		String
