一囤捻、開啟事務(wù)流程

1）在spring整合mybatis的配置文件中追加以下內(nèi)容（spring.xml）

    <!-- 配置事務(wù) -->
    <bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!-- 數(shù)據(jù)源 -->
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <tx:annotation-driven transaction-manager="dataSourceTransactionManager" />

2）在業(yè)務(wù)的實(shí)現(xiàn)層追加 @Transactional注解

前方高能：
1）若對(duì)于業(yè)務(wù)層(service)及持久的層（mapper）的掃描配置在SpringMVC的配置文件中時(shí)谅阿，一定要將這兩個(gè)類的掃描配置在spring的配置的配置文件中
2）業(yè)務(wù)層的方法一定要時(shí)public方法

ps：如果這時(shí)spring的配置文件報(bào)錯(cuò)友扰，一般都是名稱空間缺少苗傅，追加一下對(duì)應(yīng)的名稱空間即可，下面我自己的spring配置文件扳埂，僅供參考
