Chapter 5. Accessing a Database with Spring and JDBC Template Patterns

In earlier chapters, you learned about Spring core modules like the Spring IoC container, the DI pattern, container life cycle, and the used design patterns. Also you have seen how Spring makes magic using AOP. Now is the right time to move into the battlefield of real Spring applications with persisting data. Do you remember your first application during college days where you dealt with database access? That time, you probably, had to write boring boilerplate code to load database drivers, initialize your data-access framework, open connections, handle various exceptions, and to close connections. You also had to be very careful about that code. If anything went wrong, you would not have been able to make a database connection in your application, even though you would've invested a lot of time in such boring code, apart from writing the actual SQL and business code.
