This document provides an introduction to the Spring Java/JEE application framework. Spring is an open source framework that provides inversion of control and dependency injection for Java/JEE applications. It supports integration with ORM tools, web frameworks, and remoting protocols. Spring uses a lightweight configuration to wire together application components through dependency injection.

1. Introduction to Spring [email_address]

2. What is Spring Java/JEE Application Framework Main target: JEE Web Applications Apache 2 License Hosted on SourceForge Business objects as POJO

3. Integration O/R Mapping tools JDBC, Hibernate, JDO, iBatis, etc Web Frameworks Spring-WebMVC, Struts, Tapestry, etc Remoting Protocols RMI, JAX-RPC, HTTP, Hessian, Burlap,

4. Hollywood Principle “ Don't call me, I'll call you” Inversion of Control spring-ioc as core module objects/components are configured from the outside Dependency Injection setter based (JavaBeans) constructor based service lookup (jndi, ...)

5. core concepts Composition a pojo is flat by nature Lifecycle management BeanFactory Binding management (auto) wiring by name, by type, ...

6. hello world <bean id=”client” class=”Client”> <property name=”server”> <ref bean=”server”/> </bean> <bean id=server” class=”Server”/>

7. another example <bean id=”dao” class=”MyDao”> <property name=”dataSource”> <ref bean=”dataSource”/> </bean> <!--local--> <bean id=”dataSource class=”BasicDataSource”> <property name=”driverClassName” value=””/> <property name=”url” value=”..”/> </bean> <bean id=”remoteDataSource” class=”org.springframework.jndi.JndiObjectFactoryBean”> <property name=”...” > </bean> To change datasource, change the value referenced in the dao component
