AtlasMap

Since Camel 3.7

Only producer is supported

The AtlasMap component allows you to process data mapping using an AtlasMap data mapping definition. It could be either an ADM archive file or mapping definition JSON file.

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

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

URI format

atlasmap:mappingName[?options]

Where mappingName is the classpath-local URI of the AtlasMap mapping definition, either ADM archive file or mapping definition JSON file to process.

Options

The AtlasMap component supports 4 options, which are listed below.

Name Description Default Type

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

atlasContextFactory (advanced)

To use the AtlasContextFactory otherwise a new engine is created.

AtlasContextFactory

autowiredEnabled (advanced)

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

propertiesFile (advanced)

The URI of the properties file which is used for AtlasContextFactory initialization.

String

The AtlasMap endpoint is configured using URI syntax:

atlasmap:resourceUri

with the following path and query parameters:

Path Parameters (1 parameters):

Name Description Default Type

resourceUri

Required Path to the resource. You can prefix with: classpath, file, http, ref, or bean. classpath, file and http loads the resource using these protocols (classpath is default). ref will lookup the resource in the registry. bean will call a method on a bean to be used as the resource. For bean you can specify the method name after dot, eg bean:myBean.myMethod.

String

Query Parameters (6 parameters):

Name Description Default Type

allowContextMapAll (producer)

Sets whether the context map should allow access to all details. By default only the message body and headers can be accessed. This option can be enabled for full access to the current Exchange and CamelContext. Doing so impose a potential security risk as this opens access to the full power of CamelContext API.

false

boolean

contentCache (producer)

Sets whether to use resource content cache or not

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

sourceMapName (producer)

The Exchange property name for a source message map which hold java.util.Map<String, Message> where the key is AtlasMap Document ID. AtlasMap consumes Message bodies as source documents, as well as message headers as source properties where the scope equals to Document ID.

String

targetMapMode (producer)

TargetMapMode enum value to specify how multiple target documents are delivered if exist. 'MAP': Stores them into a java.util.Map, and the java.util.Map is set to an exchange property if 'targetMapName' is specified, otherwise message body. 'MESSAGE_HEADER': Stores them into message headers. 'EXCHANGE_PROPERTY': Stores them into exchange properties. ). There are 3 enums and the value can be one of: MAP, MESSAGE_HEADER, EXCHANGE_PROPERTY

MAP

TargetMapMode

targetMapName (producer)

The Exchange property name for a target document map which hold java.util.Map<String, Object> where the key is AtlasMap Document ID. AtlasMap populates multiple target documents into this map.

String

Samples

For example you could use something like

from("activemq:My.Queue").
  to("atlasmap:atlasmap-mapping.adm");

where you can export an ADM archive file from AtlasMap Data Mapper UI.

Spring Boot Auto-Configuration

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

The component supports 5 options, which are listed below.

Name Description Default Type

camel.component.atlasmap.atlas-context-factory

To use the AtlasContextFactory otherwise a new engine is created. The option is a io.atlasmap.api.AtlasContextFactory type.

AtlasContextFactory

camel.component.atlasmap.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.atlasmap.enabled

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

Boolean

camel.component.atlasmap.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.atlasmap.properties-file

The URI of the properties file which is used for AtlasContextFactory initialization.
