Perhaps that could be for you helpful:
<bean id="txProxyTemplate" abstract="true"
class="
org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager" ref="transactionManager"/>
<property name="transactionAttributes">
<props>
<prop key="save*">PROPAGATION_REQUIRED</prop>
<prop key="remove*">PROPAGATION_REQUIRED</prop>
<prop key="set*">PROPAGATION_REQUIRED</prop>
<prop key="insert*">PROPAGATION_REQUIRED</prop>
<prop key="*">PROPAGATION_REQUIRED,readOnly</prop>
For example method getUsers -> readOnly
when you have another methods you should write it here
</props>
</property>
</bean>
