项目记录-java多态实现类的调用

java多态实现类：

接口多实现类，建一个记录实现类的表，表信息要有类的注解别名，如（“”），

然后通过id查询到查到注解别名的字段，通过springboot框架的applicationContext注解类getBean来获取接口的实现类服务

  @Autowired
    private ApplicationContext applicationContext;

//TODO 异步
        IMmsApiUnifiedService mmsApiUnifiedService = (IMmsApiUnifiedService) applicationContext.getBean("MmsApiUnifiedService");
        mmsApiUnifiedService.createChildSendTask(smsSend, clientAppInfo, mmsData);

getBean(“接口名”);

IMmsApiService mmsService = clientAppHelper.getMmsService(channel);
                    MmsEntity result = mmsService.mmsSendTask(smsSendSub, mmsData);

	public IMmsApiService getMmsService(SmsChannel smsChannel) {
		SmsTempl smsTempl = smsTemplService.selectSmsTemplById(smsChannel.getTemplId());
		if (smsTempl.getTemplStatus() != 1) {
			throw new MmsApiException("通道模板不可用");
		}
		return getMmsService(smsTempl);
	}

	
	public IMmsApiService getMmsService(SmsTempl SmsTempl) {
		//String sHandler = SmsTempl.getHandler();
		SysClass sysClass = sysClassService.selectSysClassById(SmsTempl.getHandlerCall());
		if (sysClass == null) {
			throw new MmsApiException("处理服务不存在");
		}
		return getMmsService(sysClass.getAliasName());
	}

	
	public IMmsApiService getMmsService(String sHandler) {
		IMmsApiService mmsService;
		try {
			mmsService = (IMmsApiService) applicationContext.getBean(sHandler);//"MmsServiceAspirecn");
		} catch (Exception e) {
			throw new MmsApiException("通道未配置处理器，请与管理员联系");
		}
		return mmsService;
	}

	
	public IMmsCallbackService getCallbackService(SmsTempl smsTempl) {
		if (smsTempl == null)
			throw new MmsApiException("没有配置通道模板，请与管理员联系");
		Long classId = smsTempl.getHandlerCallback();
		SysClass sysClass = sysClassService.selectSysClassById(classId);
		if (sysClass == null)
			throw new MmsApiException("未找到对应的回调处理器，请与管理员联系");
		return getCallbackService(sysClass.getAliasName());
	}

	
	public IMmsCallbackService getCallbackService(String sHandler) {
		IMmsCallbackService mmsCallbackService;
		try {
			mmsCallbackService = (IMmsCallbackService) applicationContext.getBean(sHandler);//"MmsServiceAspirecn");
		} catch (Exception e) {
			throw new MmsApiException("回调处理器" + sHandler + "不存在，请与管理员联系");
		}
		return mmsCallbackService;
	}

通过通道获取模板，通过模板获取处理类的别名，

通过springboot的getBean（“类别名”）获取具体的实现类服务
