JSON Processing (JSON-P) - Home
What is JSON-P?
JSON Processing (JSON-P) is a Java API to process (for e.g. parse, generate, transform and query) JSON messages. It produces and consumes JSON text in a streaming fashion (similar to StAX API for XML) and allows to build a Java object model for JSON text using API classes (similar to DOM API for XML).
Consistent
Consistent with JAXP (Java API for XML Processing) and other Java EE and SE APIs where appropriate
Conventional
Define default mapping of Java classes and instances to JSON document counterparts
Customizable
Allow customization of the default JSON service provider
Easy to Use
Default use of the APIs should not require prior knowledge of the JSON document format and specification
To print/parse a Java Object to/from JSON
JSON-P Object Model calls
public static void main(String[] args) {
// Create Json and serialize
JsonObject json = Json.createObjectBuilder()
.add("name", "Falco")
.add("age", BigDecimal.valueOf(3))
.add("biteable", Boolean.FALSE).build();
String result = json.toString();
System.out.println(result);
}JSON-P Streaming API calls
public static void main(String[] args) {
// Parse back
final String result = "{\"name\":\"Falco\",\"age\":3,\"bitable\":false}";
final JsonParser parser = Json.createParser(new StringReader(result));
String key = null;
String value = null;
while (parser.hasNext()) {
final Event event = parser.next();
switch (event) {
case KEY_NAME:
key = parser.getString();
System.out.println(key);
break;
case VALUE_STRING:
value = parser.getString();
System.out.println(value);
break;
}
}
parser.close();
}The JSON representation
{
"name": "Falco",
"age": 3,
"bitable": false
