泛型对象的应用：常规业务逻辑模板化，使用通用的父类来定义字段，具体字段由实现类来赋予数据
代码语言：javascript复制//DEMO-1
public interface CommonTemplateService<T,F> {
public T buildCallbackParam(String orderNo);
public F doCallback(String callbackUrl, String requestBody);
}
//实现类继承
public class UserService extends AbstractCommonService implements CommonTemplateService<PartnerBaseRequest, PartnerBaseResponse> {
//DEMO-2
public interface CommonTemplateService {
public PartnerBaseRequest buildCallbackParam(String orderNo);
public PartnerBaseResponse doCallback(String callbackUrl, String requestBody);
}
//实现类继承
public class UserService extends AbstractCommonService implements CommonTemplateService {
//支付宝源码代码参考：
public interface AlipayRequest<T extends AlipayResponse>{
public abstract class AlipayResponse implements Serializable {
public <T extends AlipayResponse> T execute(AlipayRequest<T> request) throws Exception {
}
//实现类
public class AlipayAcquirePayRequest extends BaseVo implements AlipayRequest<AlipayAcquirePayResponse>{
