Java SetterlessProperty-class And Method Code Example

Here is an example of using the SetterlessProperty class in the Jackson JSON library to handle a property that does not have a setter method:

import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.databind.BeanProperty;
import com.fasterxml.jackson.databind.jsontype.TypeSerializer;
import com.fasterxml.jackson.databind.ser.std.BeanSerializerBase;
import com.fasterxml.jackson.databind.ser.std.StdSerializer;

public class SetterlessPropertySerializer extends StdSerializer<SetterlessProperty> {
  public SetterlessPropertySerializer() {

  public void serialize(SetterlessProperty value, JsonGenerator gen, SerializerProvider provider)
      throws IOException {
    gen.writeStringField("name", value.getName());

public class SetterlessProperty {
  private final String name;

  public SetterlessProperty(@JsonProperty("name") String name) { = name;

  public String getName() {
    return name;

Here, a custom serializer SetterlessPropertySerializer is defined to handle the serialization of SetterlessProperty instances, which do not have a setter method for the "name" property. The custom serializer overrides the serialize method to write the "name" property to the JSON output using the writeStringField method.

In this example, the SetterlessProperty class is a simple POJO with a single property 'name' which is read only and does not have any setter method.
