Spring JdbcTemplate

Transaction Management in Spring

Change code in employeeDao.java. employeeOperation method which is doing multiple db operations.
Add @Transactional Annotation on below method. Make some spelling mistake in one of query. You will see nothing will be inserted in DB.
Observe same code without @Transactional
If you do not use this annotation then successful queries will commit the records and failed queries will not means we will get partial data.
Remember: One transaction means everything should be successful otherwise automatically partial data will be rolled back.

Code in EmployeeDao.java as below.

     @Transactional
public void employeeOperation(Employee e) {
    saveEmployee(e);
    updateEmployee(e);
    deleteEmployee(e);
}
