SpringUtils
TemplateFactory

@Component
public class TemplateFactory {
    @Autowired
    private SpringUtils springUtils;

    public AbstractPayCallbackTemplate getPayCallbackTemplate(String templateId) {
        AbstractPayCallbackTemplate payCallbackTemplate = (AbstractPayCallbackTemplate) springUtils.getBean(templateId);
        return payCallbackTemplate;
    }
}

FactoryTempleteApp

@SpringBootApplication
@EnableAsync
@RestController
@Slf4j
public class FactoryTempleteApp {
    public static void main(String[] args) {
        SpringApplication.run(FactoryTempleteApp.class, args);
    }

    @Autowired
    private TemplateFactory templateFactory;

    @RequestMapping(value = "/factory/{id}", method = RequestMethod.GET)
    public String factory(@PathVariable("id") String id) {
        log.info("beanid:{}", id);
        //id表示beanID
        return templateFactory.getPayCallbackTemplate(id).asycCallback();
    }
}
