如何在Java中为webservice创建回调函数？

Question

我正在使用Odoo服务来获取我的网络数据。在主类我有一个读取数据的方法：

public void OdooRead() {
    OdooService.getCustomers(odoo, "myCallbackFunction");
}

所以，我确实创建了另一个类来提供这项服务：

public class OdooService {

    public static final String[] odooAllFields = {"id","name","customer_account_number","customer_group_id","segment_id","subsegment_id","economic_group_id","type_stablishment_id","street","street2","final_user","final_taxpayer","cnpj_cpf","inscr_est","ccm","cnae","phone","phone_extension","mobile","fax","email","email_extra","website","lang"};

    public static List<Customer> getCustomers(OdooClient client, "myCallbackFunction") {

        List<Customer> list = new ArrayList<>();

        ODomain domain = new ODomain();
        OdooFields odooFields = new OdooFields();
        odooFields.addAll(odooAllFields);

        String sorting = "id ASC";
        int offset = 0;
        int limit = 0;

        client.searchRead("res.partner", domain, odooFields, offset, limit, sorting, new IOdooResponse() {
        @Override
        public void onResult(OdooResult result) {
            // HERE I WANTS CALL THE CALLBACK FUNCTION TO MAIN!
        }
    });

        return list;
    }

}

因此，当方法返回web上的搜索结果时，我想向main发送一个回调函数，结果列表作为参数。而在此期间，主类正常运行，当方法完成时我刷新用户界面。
