Spring Boot Auto-Configuration

The starter supports 21 options, which are listed below.

Name Description Default Type

camel.component.rocketmq.access-channel

Access channel of RocketMQ cluster. LOCAL or CLOUD, LOCAL by default

LOCAL

String

camel.component.rocketmq.access-key

Access key for RocketMQ ACL.

String

camel.component.rocketmq.autowired-enabled

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

Boolean

camel.component.rocketmq.bridge-error-handler

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions (if possible) occurred while the Camel consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. Important: This is only possible if the 3rd party component allows Camel to be alerted if an exception was thrown. Some components handle this internally only, and therefore bridgeErrorHandler is not possible. In other situations we may improve the Camel component to hook into the 3rd party component and make this possible for future releases. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

Boolean

camel.component.rocketmq.consumer-group

Consumer group name.

String

camel.component.rocketmq.enable-trace

Whether to enable trace.

false

Boolean

camel.component.rocketmq.enabled

Whether to enable auto configuration of the rocketmq component. This is enabled by default.

Boolean

camel.component.rocketmq.lazy-start-producer

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

Boolean

camel.component.rocketmq.message-selector-type

Message Selector Type, TAG or SQL TAG by default

tag
