Spring Transaction configuration programmatically with Spring 4.3.4 version - spring

Question

We are currently migrating from xml configuration to complete annotation with java configuration based Spring application. With the annotation approach #Transactional we can achieve but the we need to write for each and every method.
In XML we configured (OLD).
<bean id="txProxyTemplate" abstract="true"
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager">
<ref bean="transactionManager" />
</property>
<property name="transactionAttributes">
<props>
<prop key="delete*">PROPAGATION_REQUIRED,ISOLATION_READ_COMMITTED</prop>
<prop key="update*">PROPAGATION_REQUIRED,ISOLATION_READ_COMMITTED</prop>
<prop key="save*">PROPAGATION_REQUIRED,ISOLATION_READ_COMMITTED</prop>
<prop key="get*">PROPAGATION_SUPPORTS,ISOLATION_READ_COMMITTED,readOnly</prop>
<prop key="is*">PROPAGATION_SUPPORTS,ISOLATION_READ_COMMITTED,readOnly</prop>
<!--<prop key="*">PROPAGATION_REQUIRED</prop> -->
</props>
</property>
</bean>
transactionManager is org.springframework.orm.hibernate3.HibernateTransactionManager
<bean id="xxxxSVC" parent="txProxyTemplate">
<property name="target">
<bean class="XXX.XXX.XXX.SVCImpl">
<property name="xxxxDao" ref="xxxDao"></property>
</bean>
</property>
</bean>
txProxyTemplate is parent class of each service class.
So, please suggest how to configure similar code in java configuration. Thanks for your valuable time spent and support us.

Bean
#Bean
public TransactionProxyFactoryBean setTransactionProperties() throws IOException {
TransactionProxyFactoryBean transactionProxyFactoryBean = new TransactionProxyFactoryBean();
transactionProxyFactoryBean.setTransactionManager(transactionManager(sessionFactory()));
Properties transactionAttributesProps = new Properties();
transactionAttributesProps.setProperty("delete*", "PROPAGATION_REQUIRED,ISOLATION_READ_COMMITTED");
transactionAttributesProps.setProperty("update*", "PROPAGATION_REQUIRED,ISOLATION_READ_COMMITTED");
transactionAttributesProps.setProperty("save*", "PROPAGATION_REQUIRED,ISOLATION_READ_COMMITTED");
transactionAttributesProps.setProperty("get*", "PROPAGATION_SUPPORTS,ISOLATION_READ_COMMITTED,readOnly");
transactionAttributesProps.setProperty("is*", "PROPAGATION_SUPPORTS,ISOLATION_READ_COMMITTED,readOnly");
transactionProxyFactoryBean.setTransactionAttributes(transactionAttributesProps);
transactionProxyFactoryBean.afterPropertiesSet();
return transactionProxyFactoryBean;
}
How to configure with each service implementation class, we can use it for single as a service layer may contain N classes. There is a method setTarget(Object target). Now how can we configure all the N classes. Please sugggest how can we configure.

A sample configuration for this case :
#Bean
public TransactionProxyFactoryBean txProxyTemplate(){
TransactionProxyFactoryBean txFactory=new TransactionProxyFactoryBean();
txFactory.setTransactionManager(new JpaTransactionManager()); // any transcation manager
txFactory.setTransactionAttributes(properties());
return txFactory;
}
#Bean
Properties properties(){
Properties properties=new Properties();
properties.put("delete*", "PROPAGATION_REQUIRED,ISOLATION_READ_COMMITTED");
//set al lthe properties
return properties;
}
#Bean
public TransactionProxyFactoryBean xxxxSVC(TransactionProxyFactoryBean txFactory){
txFactory.setTarget(testEntity());
return txFactory;
}
#Bean
TestEntity testEntity(){
return new TestEntity();
}
