在使用Spring聲明式事務時,不須要手動的開啓事務和關閉事務,可是對於一些場景則須要開發人員手動的提交事務,好比說一個操做中須要處理大量的數據庫更改,能夠將大量的數據庫更改分批的提交,又好比一次事務中一類的操做的失敗並不須要對其餘類操做進行事務回滾,就能夠將此類的事務先進行提交,這樣就須要手動的獲取Spring管理的Transaction來提交事務。java
一、applicationContext.xml配置spring
1 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 2 <property name="dataSource" ref="dataSource" /> 3 </bean> 4 5 <tx:advice id="txAdvice" transaction-manager="transactionManager"> 6 <tx:attributes> 7 <tx:method name="*" propagation="REQUIRED" rollback-for="java.lang.Exception" /> 8 <tx:method name="find*" read-only="true" propagation="SUPPORTS" /> 9 <tx:method name="get*" read-only="true" propagation="SUPPORTS" /> 10 <tx:method name="select*" read-only="true" propagation="SUPPORTS" /> 11 <tx:method name="list*" read-only="true" propagation="SUPPORTS" /> 12 <tx:method name="load*" read-only="true" propagation="SUPPORTS" /> 13 </tx:attributes> 14 </tx:advice> 15 16 <aop:config> 17 <aop:pointcut id="servicePointCut" expression="execution(* com.xxx.xxx.service..*(..))" /> 18 <aop:advisor advice-ref="txAdvice" pointcut-ref="servicePointCut" /> 19 </aop:config>
二、手動提交事務數據庫
1 @Resource(name="transactionManager") 2 private DataSourceTransactionManager transactionManager; 3 4 DefaultTransactionDefinition transDefinition = new DefaultTransactionDefinition(); 5 //開啓新事物 6 transDefinition.setPropagationBehavior(DefaultTransactionDefinition.PROPAGATION_REQUIRES_NEW); 7 TransactionStatus transStatus = transactionManager.getTransaction(transDefinition); 8 try { 9 //TODO 10 transactionManager.commit(transStatus); 11 } catch (Exception e) { 12 transactionManager.rollback(transStatus); 13 }
