serialisation and deserialization in java code example
Example 1: java deserializer
private Car parseCar(JsonNode node) {
Car car;
ObjectMapper mapper = new ObjectMapper();
SimpleModule module = new SimpleModule().addDeserializer(Car.class, new CarDeserializer());
mapper.registerModule(module);
organization = mapper.convertValue(node, Car.class);
return car;
}
public class CarDeserializer extends StdDeserializer<Car> {
public CarDeserializer() {
super(Car.class);
}
@Override
public Car deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException {
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.registerModule(new JodaModule());
Car car = new Car();
car.setName(getValueAsText(root, "carName"));
car.setDoorCount(getValueAsInt(root,"doorCount"));
car.setColor(getValueAsText(root,"color"));
car.setType(getValueAsText(root,"type"));
return car;
}
}
Example 2: serializable in JAVA
public class Employee implements java.io.Serializable {
public String name;
public String address;
public transient int SSN;
public int number;
public void mailCheck() {
System.out.println("Mailing a check to " + name + " " + address);
}
}
Example 3: a["default"].serialize(n)
var paramObj = {};
$.each($('#myForm').serializeArray(), function(_, kv) {
if (paramObj.hasOwnProperty(kv.name)) {
paramObj[kv.name] = $.makeArray(paramObj[kv.name]);
paramObj[kv.name].push(kv.value);
}
else {
paramObj[kv.name] = kv.value;
}
});
Example 4: what is serialization and deserialization in java
Serialization; when we MAP a Java object to API JSON
format (CONVERT JAVA OBJECT TO JSON);
Deserialization; API JSON/XML ^ MAP it to Java Object
(JSON TO JAVA OBJECT)
