Claus Ibsen commented on CAMEL-1475:
------------------------------------
Okay got this baby working now
{code:java}
from("direct:okay")
// marks this route as transacted, and we dont pass in any
parameters so we
// will auto lookup and use the Policy defined in the
spring XML file
.transacted()
.setBody(constant("Tiger in Action")).beanRef("bookService")
.setBody(constant("Elephant in
Action")).beanRef("bookService");
{code}
And with the Spring XML below Camel will lookup beans with the type
{{org.apache.camel.spi.Policy}} and if there are 1 policy defined it will use
that as default.
{code:xml}
<!-- START SNIPPET: e1 -->
<!-- datasource to the database -->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="org.hsqldb.jdbcDriver"/>
<property name="url" value="jdbc:hsqldb:mem:camel"/>
<property name="username" value="sa"/>
<property name="password" value=""/>
</bean>
<!-- spring transaction manager -->
<bean id="txManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- policy for required transaction used in our Camel routes -->
<bean id="PROPAGATION_REQUIRED"
class="org.apache.camel.spring.spi.SpringTransactionPolicy">
<property name="transactionManager" ref="txManager"/>
</bean>
<!-- bean for book business logic -->
<bean id="bookService"
class="org.apache.camel.spring.interceptor.BookService">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- END SNIPPET: e1 -->
{code}
Next step is to make it even easier, eg to be able to lookup the
PlatformManager and if there is 1 single defined use that one and use REQUIRED
by default.
Then we can loose the PROPAGATION_REQUIRED bean.
> transactionErrorHandler should be able to wrap routes with default policy if
> no policy defined

> Project: Apache Camel
> Issue Type: Bug
> Components: camel-core, camel-spring
> Affects Versions: 1.6.0
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Fix For: 2.0.0
>
>
> See TransactionalClientWithRollbackTest in camel-spring
> The {{.policy(required)}} is needed in the routes even though we have a
> global transaction error handler with a default policy set:
> {code}
> errorHandler(transactionErrorHandler(required));
> {code}
> So Camel should fallback and use the global policy if the route itself does
> not have a policy defined.
