## 一、概述 這里介紹系統啟動的時候，能夠被自動加載的業務機制，一些需要在系統啟動的時候就要加載的業務邏輯，可以使用這個機制來實現； 平臺提供了兩種自動啟動機制，以下分別介紹； ## 二、方案一 繼承AutoStartWhenBooting； ``` @Service public class ThirdPartyImplementationLoader extends AutoStartWhenBooting { public static List<ThirdPartyApiMeta> thirdPartyApiList = new ArrayList(); @Override public void doSomething() { Set<Class> classes = ClassUtil.getClassesInRayPackagesExtendsFrom(ThirdPartySupport.class); for (Class clazz : classes) { ThirdPartyApiMeta meta = new ThirdPartyApiMeta(); ThirdPartyApiDefinition tpad = (ThirdPartyApiDefinition) clazz.getAnnotation(ThirdPartyApiDefinition.class); meta.setApiName(tpad.name()); meta.setClazzName(clazz.getCanonicalName()); meta.setParaNames(tpad.constructorParamterNames()); thirdPartyApiList.add(meta); } } } ``` 1、用@Service注解，繼承自AutoStartWhenBooting； 2、實現自己的doSomething()方法即可； ## 三、方案二 實現接口：org.ray.framework.core.convention.processor.StartUpAction，并注解為Bean； ``` @Component public class Test implements StartUpAction { @Autowired private CardPooledQuotaDao cardPooledQuotaDao; @Override public void doAction(Rayframework rayframework) { String now = DateUtil.getDateStr(100); List<CardPooledQuota> quotaList = cardPooledQuotaDao.findByCardIdAndReviseValidTimeLessThanEqualAndReviseInvalidTimeGreaterThanEqualOrderByCreateTimeAscPackageTypeAsc(59847, now, now); System.out.print(quotaList.size()); } } ```
