Java JsonPOJOBuilder-class And Method Code Example

Here is an example of how to use the JsonPOJOBuilder annotation to deserialize JSON to a Java object using the Jackson library:

import com.fasterxml.jackson.annotation.JsonPOJOBuilder;
import com.fasterxml.jackson.databind.ObjectMapper;

public class Example {
    public static void main(String[] args) throws IOException {
        String json = "{\"name\":\"John\",\"age\":30}";
        ObjectMapper objectMapper = new ObjectMapper();
        Person person = objectMapper.readValue(json, Person.class);

    @JsonPOJOBuilder(withPrefix = "")
    public static class PersonBuilder {

    public static class Person {
        private String name;
        private int age;

        public String getName() {
            return name;

        public void setName(String name) {
   = name;

        public int getAge() {
            return age;

        public void setAge(int age) {
            this.age = age;

You can also use withPrefix in @JsonPOJOBuilder to specify the prefix for setters like "with" or "set"

@JsonPOJOBuilder(withPrefix = "set")

It will use setter method with "set" prefix for deserialization.
