Zip File DataFormat

The Zip File Data Format is a message compression and de-compression format. Messages can be marshalled (compressed) to Zip files containing a single entry, and Zip files containing a single entry can be unmarshalled (decompressed) to the original file contents. This data format supports ZIP64, as long as Java 7 or later is being used.

Marshal

In this example we marshal a regular text/XML payload to a compressed payload using Zip file compression, and send it to an ActiveMQ queue called MY_QUEUE.

from("direct:start").marshal().zipFile().to("activemq:queue:MY_QUEUE");

The name of the Zip entry inside the created Zip file is based on the incoming CamelFileName message header, which is the standard message header used by the file component. Additionally, the outgoing CamelFileName message header is automatically set to the value of the incoming CamelFileName message header, with the ".zip" suffix. So for example, if the following route finds a file named "test.txt" in the input directory, the output will be a Zip file named "test.txt.zip" containing a single Zip entry named "test.txt":

from("file:input/directory?antInclude=*/.txt").marshal().zipFile().to("file:output/directory");

Unmarshal

In this example we unmarshal a Zip file payload from an ActiveMQ queue called MY_QUEUE to its original format, and forward it for processing to the UnZippedMessageProcessor.

from("activemq:queue:MY_QUEUE").unmarshal().zipFile().process(new UnZippedMessageProcessor()); 

Dependencies

To use Zip files in your camel routes you need to add the a dependency on camel-zipfile which implements this data format.

If you use Maven you can just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions).

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