[FIXED] Spring Transaction configuration programmatically with Spring 4.3.4 version

Issue

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.

Solution

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();
    }
