How get JSON array with resttemplate

Question

API response

{
    "status": "success",
    "data": [
        {
            "id": "1",
            "employee_name": "Tiger Nixon",
            "employee_salary": "320800",
            "employee_age": "61",
            "profile_image": ""
        },
...
]
}

public class Data {

private int id;

private String employeeName;

private int employeeSalary;

private int employeeAge;

private String profileImage;

}

Setter getter and constructor has omitted

public class Employees {

private String status;
private Data[] datas;

}

public Employees getProductList() {
    ResponseEntity<Employees> result = restTemplate.exchange("http://dummy.restapiexample.com/api/v1/employees",
            HttpMethod.GET, null, Employees.class);
    return result.getBody();
}

And this is returned

Employees{status=success, datas=null}

Why datas is null?

Thanks for any help :)

Please annotate your fields as @JsonProperty and fields names to match input json:

public class Data {
    @JsonProperty
    private String id;
    @JsonProperty
    private String employee_name;
    @JsonProperty
    private String employee_salary;
    @JsonProperty
    private String employee_age;
    @JsonProperty
    private String profile_image;
}

public class Employees {
    @JsonProperty
    private String status;
    @JsonProperty
    private List<Data> data;
}
