Spring MVC - JDBCTemplate - Transactional - spring-mvc

Question

I am trying SPRING MVC with JDBCTemplate with transactional save. When it is transactional, when there is any error while saving in database, I am expecting it to rollback all database operations. Here I have considered 2 tables and saving data in both tables in a single method which has annotation #Transactional. Purposefully I was sending more text than the size declared in db for a field to see whether first table data is getting rolled back, but it saves in the first table (not getting rolled back). Please help me to solve the issue.

Please help me what am I missing.. thankssss

Answer 1

Make sure your dataSource is not setup for "autoCommit=true".
And you need to add something like this to your Beans.xml:
<tx:annotation-driven transaction-manager="transactionManager" />
