sping對dao的支援 對jdbc、ibatis、hibernate的整合

下面是對jdbc的封裝

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${jdbc.driverClassName}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> </bean> <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"> <property name="dataSource" ref="dataSource" /> </bean> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <aop:config> <aop:pointcut id="serviceMethod" expression="execution(* com.baobaotao.service.*Forum.*(..))" /> <aop:advisor pointcut-ref="serviceMethod" advice-ref="txAdvice" /> </aop:config> <tx:advice id="txAdvice" > <tx:attributes> <tx:method name="get*" read-only="false"/> <tx:method name="add*" rollback-for="PessimisticLockingFailureException"/> <tx:method name="update*"/> </tx:attributes> </tx:advice>

expression="execution(* com.xxx.service.*Forum.*(..))"

service包下類為*Forum*的檔案

全部service.*.*(..)

<tx:method name="add*" propagation="REQUIRED"/>

方法的規則 方法為add***就可以 rollback-for為指定的異常 出此異常就回滾事務

下面是記錄  無效

DefaultTransactionDefinition def = new DefaultTransactionDefinition();
TransactionStatus status = transactionManager.getTransaction(def);

JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
jdbcTemplate.update("INSERT INTO USER VALUES('Spring008', 'caterpillar', 'M', 29)");

private DataSourceTransactionManager transactionManager;

private DefaultTransactionDefinition def;

def = new DefaultTransactionDefinition();

TransactionStatus status =

　　transactionManager.getTransaction(def);
