Spring Transaction Management usage - spring

Question

Can anybody provide me an example for Spring Transaction management? I have queries like how it basically works? In Java EE , Application server container used to take care of the transaction using EJB's. I wanted to know ,how spring frameworks helps in the same way?

Answer 1

I hope Introduction to Spring Framework transaction management will help.

Answer 2

The Spring Framework’s transaction management support doesn't requires an application server.
Spring Frameworks Claims declarative transactions of spring framework offer more powerful and more productive programming model than EJB CMT.
Compared to transaction management using EJB Spring frameworks enables application developers to use a consistent programming model in any environment. Once we write our code once it can benefit from different transaction management strategies in different environments.
The Spring Framework provides both declarative and programmatic transaction management.
programmatic transaction management - developers work with the Spring Framework transaction abstraction, which can run over any underlying transaction infrastructure.
declarative model - developers typically write little or no code related to transaction management, and hence do not depend on the Spring Framework transaction API, or any other transaction API.

Answer 3

Spring framework provides central interface for transaction
management i.e. 'PlatformTransactionManager'
There are many implementations if it, one which you can quickly
relate to is DataSourceTransactionManager.
Now, this transaction manager does the lower level work of beginning,
rollback and commit of transaction for you.
If you see the source of DataSourceTransactionManager you will see
the same kind of transaction management code that you have seen when
you handle transaction using JDBC api
But importantly, all these things happen declaratively as part of
proxy advise using Spring AOP
Begin Transaction
DataSource ds = /*initialize DS here*/
Connection con = ds.getConnection();
con.setAutoCommit(false);
Commit Transaction
com.commit();
