Jackson Annotations - @JsonFilter
@JsonFilter is used to apply filter during serialization/de-serialization like which properties are to be used or not.
Example - @JsonFilter
import java.io.IOException; import java.text.ParseException; import com.fasterxml.jackson.annotation.JsonFilter; import com.fasterxml.jackson.databind.ObjectMapper; import com.fasterxml.jackson.databind.ser.FilterProvider; import com.fasterxml.jackson.databind.ser.impl.SimpleBeanPropertyFilter; import com.fasterxml.jackson.databind.ser.impl.SimpleFilterProvider; public class JacksonTester { public static void main(String args[]) throws IOException, ParseException { ObjectMapper mapper = new ObjectMapper(); Student student = new Student(1,13, "Mark"); FilterProvider filters = new SimpleFilterProvider() .addFilter( "nameFilter", SimpleBeanPropertyFilter.filterOutAllExcept("name")); String jsonString = mapper.writer(filters) .withDefaultPrettyPrinter() .writeValueAsString(student); System.out.println(jsonString); } } @JsonFilter("nameFilter") class Student { public int id; public int rollNo; public String name; Student(int id, int rollNo, String name) { this.id = id; this.rollNo = rollNo; this.name = name; } }
Output
{ "name" : "Mark" }
