一、springboot +spring-plugin
二、针对根据入参不同可能有不同实现逻辑的场景写个demo,如:针对支付宝或者微信支付渠道发起的支付请求
1）.引入相关依赖
<dependency>
<groupId>org.springframework.plugin</groupId>
<artifactId>spring-plugin-core</artifactId>
</dependency>
2).请求参数实体属性
@Data public class PayRequestVO { private String channel; private String phone; private BigDecimal money; }
支付接口:
public interface OrderPayOperationService extends Plugin<PayRequestVO> { public String orderPay(PayRequestVO vo); }
支付宝支付实现:
@Service public class AlipayOrderPayOperationServiceImpl implements OrderPayOperationService { @Override public boolean supports(PayRequestVO delimiter) { return "alipay".equalsIgnoreCase(delimiter.getChannel()); } @Override public String orderPay(PayRequestVO vo) { return "支付宝支付"; } }
微信支付实现:
@Service public class WxOrderPayOperationServiceImpl implements OrderPayOperationService { @Override public boolean supports(PayRequestVO delimiter) { return false; } @Override public String orderPay(PayRequestVO vo) { return "微信支付"; } }
将业务接口注入到插件系统:@EnablePluginRegistries({ OrderPayOperationService.class })
test:
@SpringBootApplication //Spring Boot核心注解，用于开启自动配置 @EnablePluginRegistries({ OrderPayOperationService.class }) @Slf4j public class DemoApplication { //程序可以直接在此启动 public static void main(String[] args) { ConfigurableApplicationContext context = SpringApplication.run(DemoApplication.class, args); PluginRegistry<OrderPayOperationService, PayRequestVO> orderPayOperationServicePluginRegistry = (PluginRegistry<OrderPayOperationService, PayRequestVO>) context .getBean("orderPayOperationServiceRegistry"); PayRequestVO vo = new PayRequestVO(); vo.setChannel("alipay"); vo.setPhone("1231231231"); vo.setMoney(new BigDecimal(100)); //获取插件 OrderPayOperationService orderPayOperationService = orderPayOperationServicePluginRegistry.getPluginFor(vo);//getPlugins(); //发起订单支付 String orderPay = orderPayOperationService.orderPay(vo); log.info("支付返回:{}", orderPay); } }
运行结果:
总结:
1.使用spring-plugin可以方便代码拓展功能,方便维护;
2.架构清晰,结构分层;
3.业务实现解耦,保持原有业务稳定性,新增业务无需动到框架层面.

if else太多怎么代替,太难维护?可以使用spring-plugin 插件系统
