How to get the JSONParser default settings using Jackson in Java?
All the default settings of JSON Parser can be represented using the JsonParser.Feature enumeration. The JsonParser.Feature.values() will return all the features that are available for JSONParser but whether a feature is enabled or disabled for a particular parser can be determined using the isEnabled() method of JsonParser.
Syntax
public static enum JsonParser.Feature extends Enum<JsonParser.Feature>
Example
import com.fasterxml.jackson.core.*;
import java.io.*;
public class JsonParserSettingsTest {
public static void main(String[] args) throws IOException {
String json = "[{\"name\":\"Adithya\", \"age\":\"30\"}," + "{\"name\":\"Ravi\", \"age\":\"35\"}]";
JsonFactory jsonFactory = new JsonFactory();
JsonParser jsonParser = jsonFactory.createParser(json);
for(JsonParser.Feature feature : JsonParser.Feature.values()) {
System.out.println(feature.name() + ":" + jsonParser.isEnabled(feature));
}
}
}Output
