Rison Parser and Generator for Jackson
A plugin for the Jackson streaming JSON processor v2.10.x that adds support for reading and writing JSON objects in the Rison serialization format. Support for Jackson:
Rison expresses the exact same data structures as JSON, but is much more compact and readable than JSON when encoded in a URI.
See https://github.com/Nanonid/rison for more information about Rison.
Usage
In your code, create a RisonFactory
instead of a JsonFactory
. Then read and write objects just as you do regular JSON objects. All the Jackson mapper facilities are available with Rison.
import com.bazaarvoice.jackson.rison.RisonFactory;
ObjectMapper RISON = new ObjectMapper(new RisonFactory());
String string = "(a:0,b:foo,c:'23skidoo')";
Map map = RISON.readValue(string, Map.class);
...
RISON.writeValueAsString(map);
O-Rison
If you know the value you wish to serialize is always an object, you can configure the RisonFactory
to omit the containing (
and )
characters.
ObjectMapper O_RISON = new ObjectMapper(new RisonFactory().
enable(RisonGenerator.Feature.O_RISON).
enable(RisonParser.Feature.O_RISON));
String string = "a:0,b:foo,c:'23skidoo'";
Map map = O_RISON.readValue(string, Map.class);
...
System.out.println(O_RISON.writeValueAsString(map));
A-Rison
If you know the value you wish to serialize is always an array, you can configure the RisonFactory
to omit the containing !(
and )
characters.
ObjectMapper A_RISON = new ObjectMapper(new RisonFactory().
enable(RisonGenerator.Feature.A_RISON).
enable(RisonParser.Feature.A_RISON));
String string = "item1,item2,item3";
List list = A_RISON.readValue(string, List.class);
...
System.out.println(A_RISON.writeValueAsString(list));
