本文記錄如何整合service,包括定義spring接口,在spring容器配置service以及事務控制。讓spring管理service接口。github
public interface ItemsService { //商品查詢列表 List<ItemsCustom> findItemsList(ItemsQueryVo itemsQueryVo) throws Exception; }
public class ItemsServiceImpl implements ItemsService { @Autowired private ItemsMapperCustom itemsMapperCustom; public List<ItemsCustom> findItemsList(ItemsQueryVo itemsQueryVo) throws Exception { return itemsMapperCustom.findItemsList(itemsQueryVo); } }
在resources/spring
下建立applicationContext-service.xml,文件中配置service。spring
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd"> <!-- 商品管理的service --> <bean id="itemsService" class="com.iot.learnssm.firstssm.service.impl.ItemsServiceImpl"/> </beans>
在resources/spring
下建立applicationContext-transaction.xml,在applicationContext-transaction.xml中使用spring聲明式事務控制方法。數據庫
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <!-- 事務管理器 對mybatis操做數據庫事務控制,spring使用jdbc的事務控制類 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- 數據源 dataSource在applicationContext-dao.xml中配置了 --> <property name="dataSource" ref="dataSource"/> </bean> <!-- 通知 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <!-- 傳播行爲 --> <tx:method name="save*" propagation="REQUIRED"/> <tx:method name="delete*" propagation="REQUIRED"/> <tx:method name="insert*" propagation="REQUIRED"/> <tx:method name="update*" propagation="REQUIRED"/> <tx:method name="find*" propagation="SUPPORTS" read-only="true"/> <tx:method name="get*" propagation="SUPPORTS" read-only="true"/> <tx:method name="select*" propagation="SUPPORTS" read-only="true"/> </tx:attributes> </tx:advice> <!-- aop --> <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.iot.learnssm.firstssm.service.impl.*.*(..))"/> </aop:config> </beans>
