java - example of spring declarative roolback-for? -

want declarative transactional management example in spring aop........

actually here

<aop:config>     <aop:advisor advice-ref="addadvice" pointcut="execution(* com.dao.*.*(..))"/> </aop:config> <tx:advice id="addadvice" transaction-manager="transactionmanager">     <tx:attributes>         <tx:method name="add*" propagation="required" rollback-for="" />     </tx:attributes> </tx:advice> 

so here want write rollback-for="" , there method or else? , if method method put?

in rollback-for specify name of exception. example if you want rollback your.pkg.noproductinstockexception, write

rollback-for="your.pkg.noproductinstockexception" 

this make transaction rolled if encounters exception matches specified. if exception thrown not match, propagated caller of service or wrapped transactionrolledbackexception

the transaction documentation explains:

the recommended way indicate spring framework's transaction infrastructure transaction's work rolled throw exception code executing in context of transaction. spring framework's transaction infrastructure code catch unhandled exception bubbles call stack, , make determination whether mark transaction rollback.

in default configuration, spring framework's transaction infrastructure code marks transaction rollback in case of runtime, unchecked exceptions; is, when thrown exception instance or subclass of runtimeexception. (errors - default - result in rollback). checked exceptions thrown transactional method not result in rollback in default configuration.

you can configure exception types mark transaction rollback, including checked exceptions.
