Apache Commons IO library does not have any class that provide json serialization/deserialization functionality, the libraries that you can use for this purpose are Jackson, Gson, and other libraries that provide JSON serialization/deserialization functionality.

The JsonAutoDetect annotation is provided by the Jackson library, which is used to control the serialization and deserialization of fields and methods in a class. The annotation can be applied at the class level, and it affects all fields and methods within the class. Here's an example of how you can use the JsonAutoDetect annotation to control the serialization and deserialization of a class:

@JsonAutoDetect(fieldVisibility = JsonAutoDetect.Visibility.ANY)
class Person {
    private String name;
    private int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

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

In this example, the JsonAutoDetect annotation is applied at the class level, with the fieldVisibility property set to JsonAutoDetect.Visibility.ANY, which means that all fields and methods in the class will be serialized and deserialized.

You can also use the getterVisibility, isGetterVisibility, setterVisibility, creatorVisibility properties to control the visibility of getters, setters, creators and isGetters methods.

Keep in mind that you need to have the Jackson library in your classpath in order to use this example.
