                建議指明在當前事務執行的代碼中拋出`Exception `時回滾.spring的事務底層機制會捕獲所有未處理的`Exception `絕對是否回滾事務. 默認是運行時異常和未檢查異常才會回滾,對于檢查異常是不會回滾的. 可以配置哪些指定的異常回滾,包括檢查異常: ~~~xml <tx:advice id="txAdvice" transaction-manager="txManager"> <tx:attributes> <tx:method name="get*" read-only="true" rollback-for="NoProductInStockException"/> <tx:method name="*"/> </tx:attributes> </tx:advice> ~~~ 也可以指定哪些異常不回滾,下面說明就算遇到未處理的`InstrumentNotFoundException`異常,事務也不回滾,正常提交. ~~~xml <tx:advice id="txAdvice"> <tx:attributes> <tx:method name="updateStock" no-rollback-for="InstrumentNotFoundException"/> <tx:method name="*"/> </tx:attributes> </tx:advice> ~~~ spring的事務決定回滾的規則是越精確的級別越高,如下所有的異常都回滾,除了`InstrumentNotFoundException ` ~~~xml <tx:advice id="txAdvice"> <tx:attributes> <tx:method name="*" rollback-for="Throwable" no-rollback-for="InstrumentNotFoundException"/> </tx:attributes> </tx:advice> ~~~ 也可以在編程中處理回滾,這種代碼侵入性太高 ~~~java public void resolvePosition() { try { //業務邏輯 } catch (NoProductInStockException ex) { //觸發回滾處理 TransactionAspectSupport.currentTransactionStatus().setRollbackOnly(); } } ~~~
