Javax.JSON EE bindings for graaljs
Common pattern to access JSON capabilities directly on graal vm.
JsonProvider provider = JsonProvider.provider();
URL test = GraalsonTest.class.getResource("/default.json");
Reader scriptReader = Files.newBufferedReader(Paths.get(test.toURI()));
JsonReader reader = Json.createReader(scriptReader);
JsonObject jsonObject = reader.readObject();
javax.script.Bindings result = (Bindings) new JsonObjectBindings(jsonObject);
System.out.println(result.toString());
Writer writer = new OutputStreamWriter(System.out);
JsonWriter jwriter = Json.createWriter(writer);
jwriter.write(jsonObject);
Load from json resource
{
"firstName": "John", "lastName": "Smith", "age": 25,
"address" : {
"streetAddress": "21 2nd Street",
"city": "New York",
"state": "NY",
"postalCode": "10021"
},
"phoneNumber": [
{ "type": "home", "number": "212 555-1234" },
{ "type": "fax", "number": "646 555-4567" }
]
}
Or build from objects
JsonBuilderFactory factory = Json.createBuilderFactory(config);
JsonObject value = factory.createObjectBuilder()
.add("firstName", "John")
.add("lastName", "Smith")
.add("age", 25)
.add("address", factory.createObjectBuilder()
.add("streetAddress", "21 2nd Street")
.add("city", "New York")
.add("state", "NY")
.add("postalCode", "10021"))
.add("phoneNumber", factory.createArrayBuilder()
.add(factory.createObjectBuilder()
.add("type", "home")
.add("number", "212 555-1234"))
.add(factory.createObjectBuilder()
.add("type", "fax")
.add("number", "646 555-4567")))
.build();
