由于amoeba不能处理事务,所以得在应用层进行事务处理,方案如下:
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="${jdbc.driverClass}" />
<property name="jdbcUrl" value="${jdbc.url}" />
<property name="user" value="${jdbc.user}" />
<property name="password" value="${jdbc.password}" />
<property name="minPoolSize" value="${minPoolSize}" />
<property name="initialPoolSize" value="${initialPoolSize}" />
<property name="maxPoolSize" value="${maxPoolSize}" />
<property name="acquireIncrement" value="${acquireIncrement}" />
<property name="maxStatementsPerConnection" value="${maxStatementsPerConnection}" />
<property name="maxStatements" value="${maxStatements}" />
</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>
在应用层:
DefaultTransactionDefinition definition = new DefaultTransactionDefinition(); definition.setTimeout(20); TransactionStatus txStatus = transactionManager.getTransaction(definition); try {
//事务处理
transactionManager.commit(txStatus);
}catch (Exception e) { transactionManager.rollback(txStatus); e.printStackTrace(); }
这样能够保证在不同机器上的mysql的事务统一
