To make the DefaultMyService service object as transactional, the configuration in the
applicationContext.xml file is:
<!-- this is the service object that we want to make transactional -->
<bean id="myService" class="a.b.service.DefaultMyService"/>
Defining the Transactional Advice
The next step is to add the transactional advice to the transactional object. The transaction
semantics that must be applied are encapsulated in the <tx:advice/> definition.
If you plan to define the transaction advice with the business rule as follows:
“All methods starting with 'get' are to execute in the read-only
transaction mode and rest of the methods are to execute with the default
transaction mode”,
the <tx:advice/> definition is configured as:
<!-- the transactional advice -->
<tx:advice id="<transactional advice id>" transaction-manager="<transaction manager id>">
<!-- the transactional semantics... -->
<tx:attributes>
<!-- all methods starting with 'get' are read-only -->
<tx:method name="get*" read-only="true"/>
<!-- other methods use the default transaction settings -->
<tx:method name="*"/>
</tx:attributes>
</tx:advice>
The transaction-manager attribute of the <tx:advice/> tag is set to the name of the
PlatformTransactionManager bean that will drive the transactions.
For example:
Assume that the first two methods of the MyService interface (getMyObject(String) and
getMyObject(String, String)) must execute in the context of a transaction with read-only
semantics, and that the other methods (insertMyObject(MyObject) and
updateMyObject(MyObject)) must execute in the context of a transaction with read-write
Semantics. The configuration is:
<!-- the transactional advice -->
<tx:advice id="txAdvice" transaction-manager="txManager">
<!-- the transactional semantics... -->
<tx:attributes>
<!-- all methods starting with 'get' are read-only -->
<tx:method name="get*" read-only="true"/>
<!-- other methods use the default transaction settings -->
<tx:method name="*"/>
</tx:attributes>
</tx:advice>
