Vert.x

Since Camel 2.12

Both producer and consumer are supported

The Vert.x component is for working with the Vertx EventBus.

The vertx EventBus sends and receives JSON events.

The version of Vert.x, used by the component, requires at least Java 1.8 at runtime.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-vertx</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

URI format

vertx:channelName[?options]

Options

The Vert.x component supports 9 options, which are listed below.

Name Description Default Type

host (common)

Hostname for creating an embedded clustered EventBus

String

port (common)

Port for creating an embedded clustered EventBus

int

timeout (common)

Timeout in seconds to wait for clustered Vertx EventBus to be ready. The default value is 60.

60

int

vertx (common)

To use the given vertx EventBus instead of creating a new embedded EventBus

Vertx

vertxOptions (common)

Options to use for creating vertx

VertxOptions

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. 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

lazyStartProducer (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

basicPropertyBinding (advanced)

Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

vertxFactory (advanced)

To use a custom VertxFactory implementation

VertxFactory

The Vert.x endpoint is configured using URI syntax:

vertx:address

with the following path and query parameters:

Path Parameters (1 parameters):

Name Description Default Type

address

Required Sets the event bus address used to communicate

String

Query Parameters (7 parameters):

Name Description Default Type

pubSub (common)

Whether to use publish/subscribe instead of point to point when sending to a vertx endpoint.

Boolean

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. 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

exceptionHandler (consumer)

To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.

ExceptionHandler

exchangePattern (consumer)

Sets the exchange pattern when the consumer creates an exchange. The value can be one of: InOnly, InOut, InOptionalOut

ExchangePattern

lazyStartProducer (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

basicPropertyBinding (advanced)

Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

synchronous (advanced)

Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).

false

boolean

Whether to use publish/subscribe instead of point to point when sending to a vertx endpoint.

You can append query options to the URI in the following format, ?option=value&option=value&...

Connecting to the existing Vert.x instance

If you would like to connect to the Vert.x instance already existing in your JVM, you can set the instance on the component level:

Vertx vertx = ...;
VertxComponent vertxComponent = new VertxComponent();
vertxComponent.setVertx(vertx);
camelContext.addComponent("vertx", vertxComponent);

Spring Boot Auto-Configuration

When using vertx with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-vertx-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 10 options, which are listed below.

Name Description Default Type

camel.component.vertx.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.vertx.bridge-error-handler

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. 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.vertx.enabled

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

Boolean

camel.component.vertx.host

Hostname for creating an embedded clustered EventBus

String

camel.component.vertx.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.vertx.port

Port for creating an embedded clustered EventBus

Integer

camel.component.vertx.timeout

Timeout in seconds to wait for clustered Vertx EventBus to be ready. The default value is 60.

60

Integer

camel.component.vertx.vertx

To use the given vertx EventBus instead of creating a new embedded EventBus. The option is a io.vertx.core.Vertx type.

Vertx

camel.component.vertx.vertx-factory

To use a custom VertxFactory implementation. The option is a io.vertx.core.spi.VertxFactory type.

VertxFactory

camel.component.vertx.vertx-options

Options to use for creating vertx. The option is a io.vertx.core.VertxOptions type.
