Overview Of The Spring Framework

Front 1

Goal of the Spring framework

Back 1

Provide comprehensive infrastructural support for developing enterprise Java applications:
- Springs deals with the plumbing
- So you can focus on solving the domain problem

Front 2

Spring's role in the enterprise application architecture

Back 2

- Core support
- Web application development support
- Enterprise application development support

Front 3

Core support

Back 3

- Application Configuration
- Enterprise Integration
- Testing
- Data Access

Front 4

Core support: Application Configuration

Back 4

Support for assembling application system from it's parts (POJO):
- parts do not worry about finding each other
- any part can easily be swapped out (.e.g. for testing)

Front 5

Core Support: Enterprise Integration

Back 5

Since enterprise apps don't work in isolation, they require enterprise services and resources.

-Spring helps you integrate the services into your app while keeping application code simple and testable

-Spring plugs into all JavaEE app servers
while capable of standalone use

Front 6

Java enterprise services and resources high level

Back 6

- Database Transactions
- Security
- Messaging
- Remote access
- Caching

Front 7

Core Support: Testing

Back 7

Spring enables unit testability:
- decouples objects from their environment
- making it easier to test each piece of your app in isolation

Spring provides system testing support:
-helps you test all the pieces together

Front 8

Core Support: Accessing Data

Back 8

Most EE apps access data in rel. database:
- to carry out business functions
- to enforce business rules

Spring makes it easier to do effectively:
- Manages resources for you
- Provides API helpers
- Supports all major data access tech (JDBC, Hibernate, JPA, Ibatis etc)

Front 9

Web app development support

Back 9

Struts and JSF integration
Spring MVC and Web Flow:
- handle user actions
- validate input forms
- enforce site navigation rules
- manage conversational state
- render responses (HTML, XML, etc)

Front 10

Enterprise app development support

Back 10

- developing web services
- adding manageability
- integrating messaging infrastructure
- securing services and providing object access control
- scheduling jobs
