CBOR

Since Camel 3.0

CBOR is a Data Format that uses the Jackson library with the CBOR extension to unmarshal a CBOR payload into Java objects or to marshal Java objects into a CBOR payload.

from("activemq:My.Queue")
    .unmarshal().cbor()
    .to("mqseries:Another.Queue");

Usage

CBOR Options

The CBOR dataformat supports 10 options, which are listed below.

Name Default Java Type Description

objectMapper (advanced)

String

Lookup and use the existing CBOR ObjectMapper with the given id when using Jackson.

useDefaultObjectMapper (common)

true

Boolean

Whether to lookup and use default Jackson CBOR ObjectMapper from the registry.

unmarshalType (common)

String

Class name of the java type to use when unmarshalling.

collectionType (advanced)

String

Refers to a custom collection type to lookup in the registry to use. This option should rarely be used, but allows to use different collection types than java.util.Collection based as default.

useList (common)

false

Boolean

To unmarshal to a List of Map or a List of Pojo.

allowUnmarshallType (common)

false

Boolean

If enabled then Jackson CBOR is allowed to attempt to use the CamelCBORUnmarshalType header during the unmarshalling. This should only be enabled when desired to be used.

prettyPrint (common)

false

Boolean

To enable pretty printing output nicely formatted. Is by default false.

allowJmsType (advanced)

false

Boolean

Used for JMS users to allow the JMSType header from the JMS spec to specify a FQN classname to use to unmarshal to.

enableFeatures (common)

String

Set of features to enable on the Jackson com.fasterxml.jackson.databind.ObjectMapper. The features should be a name that matches a enum from com.fasterxml.jackson.databind.SerializationFeature, com.fasterxml.jackson.databind.DeserializationFeature, or com.fasterxml.jackson.databind.MapperFeature Multiple features can be separated by comma.

disableFeatures (common)

String

Set of features to disable on the Jackson com.fasterxml.jackson.databind.ObjectMapper. The features should be a name that matches a enum from com.fasterxml.jackson.databind.SerializationFeature, com.fasterxml.jackson.databind.DeserializationFeature, or com.fasterxml.jackson.databind.MapperFeature Multiple features can be separated by comma.

Using CBOR in Spring DSL

When using Data Format in Spring DSL, you need to declare the data formats first. This is done in the DataFormats XML tag.

<dataFormats>
    <!-- here we define a CBOR data format with the id test, and that it should use the TestPojo as the class type when
    doing unmarshal. -->
    <cbor id="test" unmarshalType="org.apache.camel.component.cbor.TestPojo"/>
</dataFormats>

And then you can refer to this id in the route:

<route>
    <from uri="direct:back"/>
    <unmarshal><custom ref="test"/></unmarshal>
    <to uri="mock:reverse"/>
</route>

Dependencies

<dependency>
   <groupId>org.apache.camel</groupId>
   <artifactId>camel-cbor</artifactId>
   <version>x.x.x</version>
</dependency>

Spring Boot Auto-Configuration

When using cbor 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-cbor-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 11 options, which are listed below.

Name Description Default Type

camel.dataformat.cbor.allow-jms-type

Used for JMS users to allow the JMSType header from the JMS spec to specify a FQN classname to use to unmarshal to.

false

Boolean

camel.dataformat.cbor.allow-unmarshall-type

If enabled then Jackson CBOR is allowed to attempt to use the CamelCBORUnmarshalType header during the unmarshalling. This should only be enabled when desired to be used.

false

Boolean

camel.dataformat.cbor.collection-type

Refers to a custom collection type to lookup in the registry to use. This option should rarely be used, but allows to use different collection types than java.util.Collection based as default.

String

camel.dataformat.cbor.disable-features

Set of features to disable on the Jackson com.fasterxml.jackson.databind.ObjectMapper. The features should be a name that matches a enum from com.fasterxml.jackson.databind.SerializationFeature, com.fasterxml.jackson.databind.DeserializationFeature, or com.fasterxml.jackson.databind.MapperFeature Multiple features can be separated by comma.

String

camel.dataformat.cbor.enable-features

Set of features to enable on the Jackson com.fasterxml.jackson.databind.ObjectMapper. The features should be a name that matches a enum from com.fasterxml.jackson.databind.SerializationFeature, com.fasterxml.jackson.databind.DeserializationFeature, or com.fasterxml.jackson.databind.MapperFeature Multiple features can be separated by comma.

String

camel.dataformat.cbor.enabled

Whether to enable auto configuration of the cbor data format. This is enabled by default.

Boolean

camel.dataformat.cbor.object-mapper

Lookup and use the existing CBOR ObjectMapper with the given id when using Jackson.

String

camel.dataformat.cbor.pretty-print

To enable pretty printing output nicely formatted. Is by default false.

false

Boolean

camel.dataformat.cbor.unmarshal-type

Class name of the java type to use when unmarshalling.

String

camel.dataformat.cbor.use-default-object-mapper

Whether to lookup and use default Jackson CBOR ObjectMapper from the registry.

true

Boolean

To unmarshal to a List of Map or a List of Pojo.

false

Boolean
