一、基本配置
<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"> <!-- 连接池配置 --> <bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig"> <property name="poolName" value="springHikariCP" /> <property name="connectionTestQuery" value="SELECT 1" /> <property name="dataSourceClassName" value="${jdbc.driverClassName}" /> <property name="dataSourceProperties"> <props> <prop key="url">${jdbc.url}</prop> <prop key="user">${jdbc.username}</prop> <prop key="password">${jdbc.password}</prop> <prop key="cachePrepStmts">true</prop> <prop key="prepStmtCacheSize">250</prop> <prop key="prepStmtCacheSqlLimit">2048</prop> </props> </property> <!-- 控制自动提交行为 default:true --> <property name="autoCommit" value="true"/> <!--连接池获取的连接是否只读 default:false--> <property name="readOnly" value="false"/> <!--最大连接超时时间 default:30秒--> <property name="connectionTimeout" value="30000"/> <!--最大空闲超时时间 default:10分钟 --> <property name="idleTimeout" value="600000"/> <!--连接池中一个连接的最大生命周期 default:30分钟--> <property name="maxLifetime" value="1800000 "/> </bean> <bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource" destroy-method="close"> <constructor-arg ref="hikariConfig" /> </bean> <!-- define the SqlSessionFactory --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="configLocation" value="classpath:META-INF/mybatis/mybatis-config.xml"/> <property name="mapperLocations" value="classpath:META-INF/mybatis/mapper/*.xml"/> </bean> <!-- scan for mappers and let them be autowired --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="annotationClass" value="org.springframework.stereotype.Repository"/> <property name="basePackage" value="com.geenk.market.dal"/> </bean> <!-- 声明编码方式事务 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <bean id="transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate"> <property name="transactionManager" ref="transactionManager"/> <!--ISOLATION_DEFAULT 表示由使用的数据库决定 --> <property name="isolationLevelName" value="ISOLATION_DEFAULT"/> <property name="propagationBehaviorName" value="PROPAGATION_REQUIRED"/> </bean> <!-- 启动使用注解实现声明式事务管理的支持--> <tx:annotation-driven transaction-manager="transactionManager" /> </beans>
该配置方案是最基本的事物配置方案,MyBatis自动参与到spring事务管理中,无需额外配置,只要org.mybatis.spring.SqlSessionFactoryBean引用的数据源与DataSourceTransactionManager引用的数据源一致即可,否则事务管理会不起作用。但是缺点是事物的传播行为都是一致的,不能精确的为特定的方法配置事物的传播行为。
二、增强配置
<tx:advice id="transactionAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="modify*" propagation="REQUIRED" /> <tx:method name="edit*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="remove*" propagation="REQUIRED" /> <tx:method name="get*" propagation="SUPPORTS" /> <tx:method name="find*" propagation="SUPPORTS" /> <tx:method name="load*" propagation="SUPPORTS" /> <tx:method name="search*" propagation="SUPPORTS" /> <tx:method name="datagrid*" propagation="SUPPORTS" /> <tx:method name="*" propagation="SUPPORTS" /> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut id="transactionPointcut" expression="execution(* com.geenk.market.dal..*Impl.*(..))" /> <aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" /> </aop:config>
改配置方案可以精确事物到特定方法,对数据库有改动的操作如新增、修改、和删除。以事物方式来进行,对数据库无改动的操作则可以以非事物的方式来进行。
三、基于注解配置
<!-- 配置事务管理器--> <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> <tx:annotation-driven transaction-manager="txManager"/>
然后只要在要使用的类或方法上加上注解@Transactional便可。
