Map/access array inside object on Pojo

Question

How can I access and map an array inside an object on Pojo Spring Boot?

This is what I wanted to map

{
    "customers": [
        {
            "customerId": "0434556574",
            "paymentCode": "90501"
        }
    ]
}

You would need to classes to match the JSON structure:

public class CustomersData {
    private List<Customer> customers;

    // Constructor, getter and setter
}

public class Customer {
    private String customerId;
    private String paymentCode;

    // Constructor, getter and setter
}

Important thing is to make sure your JSON properties name matches the attributes name in your Java classes (thus avoiding explicit mapping between them).
