|
| **Since Camel 2.14** |
|
|
| This component provides a dataformat for avro, which allows |
| serialization and deserialization of messages using Apache Avro’s binary |
| dataformat. Since Camel 3.2 rpc functionality was moved into separate |
| `camel-avro-rpc` component. |
|
|
| There is also `camel-jackson-avro` which is a more powerful Camel |
| dataformat for using Avro. |
|
|
| Maven users will need to add the following dependency to their `pom.xml` |
| for this component: |
|
|
| <dependency> |
| <groupId>org.apache.camel</groupId> |
| <artifactId>camel-avro</artifactId> |
| <version>x.x.x</version> |
| <!-- use the same version as your Camel core version --> |
| </dependency> |
| |
| You can easily generate classes from a schema, using maven, ant etc. |
| More details can be found at the [Apache Avro |
| documentation](http://avro.apache.org/docs/current/). |

| ## Avro Data Format usage |
|
|
| Using the avro data format is as easy as specifying that the class that |
| you want to marshal or unmarshal in your route. |
|
|
| AvroDataFormat format = new AvroDataFormat(Value.SCHEMA$); |
| |
| from("direct:in").marshal(format).to("direct:marshal"); |
| from("direct:back").unmarshal(format).to("direct:unmarshal"); |
| |
| Where Value is an Avro Maven Plugin Generated class. |
|
|
| or in XML |
|
|
| <camelContext id="camel" xmlns="http://camel.apache.org/schema/spring"> |
| <route> |
| <from uri="direct:in"/> |
| <marshal> |
| <avro instanceClass="org.apache.camel.dataformat.avro.Message" library="ApacheAvro"/> |
| </marshal> |
| <to uri="log:out"/> |
| </route> |
| </camelContext> |
| |
| An alternative can be to specify the dataformat inside the context and |
| reference it from your route. |
|
|
| <camelContext id="camel" xmlns="http://camel.apache.org/schema/spring"> |
| <dataFormats> |
| <avro id="avro" instanceClass="org.apache.camel.dataformat.avro.Message" library="ApacheAvro"/> |
| </dataFormats> |
| <route> |
| <from uri="direct:in"/> |
| <marshal><custom ref="avro"/></marshal> |
| <to uri="log:out"/> |
| </route> |
| </camelContext> |
| |
| In the same manner, you can unmarshal using the avro data format. |
