Yes, you need a duplicate transaction advice. Notice in the following configuration that the pointcut expression selects a specific CompanyService bean.
<bean id="companyService1" class="com.company.service.CompanyServiceImpl">
<property name="companyDao">
<bean class="com.company.service.CompanyDAO">
<property name="dataSource" ref="dataSource1"/>
</bean>
</property>
</bean>
<aop:config>
<aop:pointcut
id="companyServicePoint1"
expression="bean(companyService1)"/>
<aop:advisor
advice-ref="companyServiceTxAdvice1"
pointcut-ref="companyServicePoint1"/>
</aop:config>
<tx:advice id="companyServiceTxAdvice1" transaction-manager="txManager1">
<tx:attributes>
<!-- set propogation required on create methods, all others are read-only -->
<tx:method name="create*" propagation="REQUIRED"/>
<tx:method name="*" read-only="true"/>
</tx:attributes>
</tx:advice>
<bean
id="txManager1"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource1"/>
</bean>
To configure another CompanyService bean, you need to duplicate the same verbose boilerplate. Another way to demarcate transactions in Spring uses TransactionProxyFactoryBean. It's slighty less verbose because it uses a parent bean definition to configure common properties inherited by child beans.
<bean
id="baseTransactionProxy"
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"
abstract="true">
<property name="transactionAttributes">
<props>
<prop key="create*">PROPAGATION_REQUIRED</prop>
<prop key="*">PROPAGATION_REQUIRED,readOnly</prop>
</props>
</property>
</bean>
<bean id="companyService1" parent="baseTransactionProxy">
<property name="transactionManager" ref="txManager1"/>
<property name="target">
<bean class="com.company.service.CompanyServiceImpl">
<property name="companyDao">
<bean class="com.company.service.CompanyDAO">
<property name="dataSource" ref="dataSource1"/>
</bean>
</property>
</bean>
</property>
</bean>
<bean
id="txManager1"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource1"/>
</bean>
