Mash is a wrapper for a deeply nested map of maps. It simplifies navigating json structures, providing property like access to the data.
git clone http://github.com/coder36/mash.git
cd mash
mvn clean install
The mash-1.0.jar file will be built into the target folder.
The url: http://pure-savannah-9942.herokuapp.com/bill.json serves up
{
"statement": {
"generated": "2015-01-11",
"period": {
"from": "2015-01-26",
"to": "2015-02-25"
}
},
"total": 136.03
}
Read in the json, then wrap in Mash:
Mash json = new Mash( (Map) new RestTemplate().getForObject( "http://pure-savannah-9942.herokuapp.com/bill.json", Map.class ));
Accessing properties is as simple as:
double total = (Double) json.get( "total" );
String period_from = json.get_s( "statement.period.from" );
String period_to = json.get_s( "statement.period.to" );
//or
Mash period = (Mash) json.get( "statement.period" );
period_to = (String) period.get("to");
- A missing property will yield an empty string.
The idea for Mash came from Hashie - a ruby gem.
