1. Spring Quick Start Introducing the Spring Application Context and Spring’s XML-based configuration language
2.
3. How Spring Works Spring ApplicationContext Fully configured application system Ready for use Configuration Instructions Your Application Classes (POJOs) Creates
4.
5. Configuration Instructions <beans> <bean id = “transferService” class = “app.impl.TransferServiceImpl” > <constructor-arg ref = “accountRepository” /> </bean> <bean id = “accountRepository” class = “app.impl.JdbcAccountRepository” > <constructor-arg ref = “dataSource” /> </bean> <bean id = “dataSource” class = “com.oracle.jdbc.pool.OracleDataSource” > <property name = “URL” value = “jdbc:oracle:thin:@localhost:1521:BANK” /> <property name = “user” value = “moneytransfer-app” /> </bean> </beans>
6. Creating and Using the Application // Create the application from the configuration ApplicationContext context = new ClassPathXmlApplicationContext( “application-config.xml” ); // Look up the application service interface TransferService service = (TransferService) context.getBean( “transferService” ); // Use the application service.transfer( new MonetaryAmount( “300.00” ), “1” , “2” );
7. Inside the Spring A pplication Context // Create the application from the configuration ApplicationContext context = new ClassPathXmlApplicationContext( “application-config.xml” ); Application Context OracleDataSource dataSource JdbcAccountRepository accountRepository TransferServiceImpl transferService

Editor's Notes
Emphasize this presentation will show how to hit the ground running with core Spring feature set.
The quick start should be “quick” -- communicate at a high level what has to be done to get a basic Spring-powered application up and running
Let’s start with a high level picture of how Spring works… A good analogy is an automobile plant. At a auto plant cars are assembled from parts on an assembly line. Workers on the line have an instruction manual that tells how to piece together the parts to build a car. So, you can view Spring as an application assembler where the parts are your Java components, and the instructions provided to Spring act as the manual for the assembly process. After assembly, you have a fully configured system ready to be used--just like after car assembly, you have a fully configured car ready to be driven. Parts can be interchanged, can be used in other vehicles (systems), etc.
Focus on the relationships between the elements rather than they syntax itself.
