Slide 2: What is Spring?  Spring is a lightweight container, with wrappers that make it easy to use many different services and frameworks. Lightweight containers accept any JavaBean, instead of specific types of components.  Spring is very popular  Spring is for lightweight enterprise Java  J2EE should be easier to use  It's best to program to interfaces, rather than classes  JavaBeans offer a great way of configuring applications  OO design is more important than any implementation technology  Checked exceptions are overused in Java  Testability is essential

Slide 3: Why use Spring?  The most complete lightweight container, providing centralized, automated configuration and wiring of your application objects. The container is non-invasive, capable of assembling a complex system from a set of loosely-coupled components (POJOs) in a consistent and transparent fashion.   A common abstraction layer for transaction management, allowing for pluggable transaction managers, and making it easy to demarcate transactions without dealing with low-level issues.  A JDBC abstraction layer that simplifies error handling and greatly reduces the amount of code you'll need to write.  Integration with TopLink, Hibernate, JDO, and iBATIS SQL Maps, in terms of resource holders, DAO implementation support and transaction strategies.  AOP functionality, fully integrated into Spring configuration management.  A flexible MVC web application framework, highly configurable, accommodates multiple view technologies (JSP, Velocity, etc).

Slide 4: Real world usages  Voca, core systems  Virgin Mobile UK, B2C website  The European Patent Office, publicly accessed system across 25 countries  French Tax Authority, migration of systems built on EJB 2.x  Dekabank (major German domestic bank), multi-channel, mission- critical trading application  Symantec Corp., technical support case tracking tool  US National Healthcare Provider System, portal providing fee information  JP Morgan Chase  FA Premier League, football  World of Warcraft, gaming  Confluence, enterprise knowledge base/wiki  Alfresco, open-standards content repository  Liferay Portal, open-source portal platform  Banking and finance, high-volume websites, health and pharmaceutical engineering, education, government, media and publishing

Slide 5: What’s new in Spring 2.0  Inversion of Control (IoC) container  Easier XML configuration  New bean scopes  Extensible XML authoring  Aspect Oriented Programming (AOP)  Easier AOP XML configuration  Support for @AspectJ aspects  The Middle Tier  Easier configuration of declarative transactions in XML  JPA  Asynchronous JMS  Easier JDBC programming  The Web Tier  A form tag library for SpringMVC  Sensible defaulting in SpringMVC  Portlet framework  Everything else  Dynamic language support  JMX  Task scheduling  Java 5 (Tiger) support

Slide 6: What’s new in Spring 2.1  Annotation-based configuration  JCA-based message endpoint management  New "context" and "jms" XML configuration namespaces  JDK 1.6 and Java EE 5 support  Currently M1 (GA in May 2006)

Slide 7: Similar configuration-related projects  Spring-Annotation  a library that enables the use or annotations to configure your application using spring- framework as a backend.  Spring Java Configuration Project  an experiment in producing a Java-based alternative to configuring Spring Application Contexts
