Java JsonView-class And Method Code Example

I apologize for any confusion, but there is no class called "JsonView" in the Apache Commons IO library. This library provides utility classes for working with IO operations such as file manipulation, input/output streams, and file filters. It doesn't include any functionality for working with JSON views.

However, if you're using Jackson for JSON serialization and deserialization, it does provide a feature called "JSON Views" which allows you to define different views of the same object, and then selectively include or exclude properties from the serialized JSON based on the view.

Here's an example of how you can use JSON Views with the Jackson library:

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

public class JsonViewExample {
    public static void main(String[] args) throws Exception {
        ObjectMapper mapper = new ObjectMapper();

        // Define a Person object
        Person person = new Person("John", "Doe", 30);

        // Serialize the object to a JSON string using the Public view
        String json = mapper.writerWithView(Views.Public.class).writeValueAsString(person);

class Person {
    public interface Views {
        interface Public {}

    private String firstName;

    private String lastName;

    private int age;

    public Person(String firstName, String lastName, int age) {
        this.firstName = firstName;
        this.lastName = lastName;
        this.age = age;

    // getters and setters...

This will output the following JSON string:


As you can see, only the firstName and age properties are included in the JSON string, because those are the only properties that have been annotated with the @JsonView(Views.Public.class) annotation. The lastName property is not included because it is not annotated.

You can create different views and use them to include or exclude properties based on your needs.

Please note that this is just a basic example, and the actual implementation might vary depending on your use case.
