TransactionManager只读= true不适用于mysql ReplicationDriver

Question

We are using com.mysql.jdbc.ReplicationDriver to connect Master/Slave. We configure the transactionManager as follow.

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

<tx:advice id="txHbAdvice" transaction-manager="transactionManager">
    <tx:attributes>
        <tx:method name="get*" read-only="true" />
    </tx:attributes>
</tx:advice>

I set the read-only parameter to true but it doesn't set java.sql.Connection.setReadonly() method to true. All the read queries are still come to master server.

There is an open issue for similar problem here . Is there anyone having a solution to this problem?

Answer 1

My suggestion is to write aspect around @Transactional annotation, get current running session and then invoke doWork(Work work) → and set connection.setReadOnly if @transaction has readonly attribute set. I have not tried this solution, but I think it should work.
