Since Camel 2.0
The GZip Deflater Data Format is a message compression and de-compression format. It uses the same deflate algorithm that is used in the Zip data format, although some additional headers are provided. This format is produced by popular
gunzip tool. Messages marshalled using GZip compression can be unmarshalled using GZip decompression just prior to being consumed at the endpoint. The compression capability is quite useful when you deal with large XML and Text based payloads or when you read messages previously comressed using
This dataformat is not for working with gzip files such as uncompressing and building gzip files. Instead use the zipfile dataformat.
The GZip Deflater dataformat supports 1 options, which are listed below.
| || || |
Whether the data format should set the Content-Type header with the type from the data format if the data format is capable of doing so. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSON etc.
In this example we marshal a regular text/XML payload to a compressed payload employing gzip compression format and send it an ActiveMQ queue called MY_QUEUE.
In this example we unmarshal a gzipped payload from an ActiveMQ queue called MY_QUEUE to its original format, and forward it for processing to the
When using zip-deflater 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-zip-deflater-starter</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency>
The component supports 3 options, which are listed below.
Whether to enable auto configuration of the gzipdeflater data format. This is enabled by default.
To specify a specific compression between 0-9. -1 is default compression, 0 is no compression, and 9 is best compression.
Whether to enable auto configuration of the zipdeflater data format. This is enabled by default.
