Spring Framework 1.0 Final Released

We are pleased to announce that Spring
Framework 1.0 final

has just been released.

1. SCOPE


Spring 1.0 is a complete Java/J2EE application framework, covering the
following functionality:

  • the most sophisticated lightweight
    container available today, with various flavors of setter and
    constructor injection

  • AOP interception framework based on
    the AOP Alliance interfaces, integrated with the core container

  • JNDI support classes, allowing for
    easy wiring of Spring-managed beans with JNDI-located objects

  • application context concept,
    providing resource loading and message access abstractions

  • generic transaction management with
    pluggable strategies, supporting declarative and programmatic
    demarcation

  • support for source-level metadata,
    with Commons Attributes as default implementation (e.g. for transaction
    attributes)

  • generic DAO support, providing a
    generic data access exception hierarchy for use with any data access
    strategy

  • JDBC abstraction that simplifies
    resource and error handling, also covering BLOB/CLOB support

  • Hibernate support, providing
    SessionFactory management and transaction-scoped ThreadLocal Sessions

  • support classes for JDO 1.0 and
    iBATIS SQL Maps 1.3/2.0, integrated with Spring’s transaction
    management

  • mail sender abstraction, with
    special support for JavaMail including convenient handling of file
    attachments

  • scheduling support for Quartz and
    Timer, making it easy to invoke methods of Spring-managed beans

  • remoting support for RMI, JAX-RPC
    and Caucho’s Hessian/Burlap, for easy exposure of Spring-managed beans

  • convenience classes for accessing
    and implementing EJBs, both local and remote

  • web application context, for
    loading a Spring application context in a web environment

  • flexible web MVC framework, built
    on strategy interfaces and integrated with various view technologies


A unique benefit of
Spring is the ability to apply
declarative
transactions to any POJO, with JTA or a local transaction strategy:
This allows to have lightweight transactional business objects in any
sort of environment, for example in a web app running on plain Tomcat.
Spring’s transaction management is also capable of managing associated
resources like Hibernate Sessions, avoiding the burden of custom
ThreadLocal Sessions.


Building on the
resource management infrastructure,
Spring’s HibernateTemplate significantly simplifies the implementation
of Hibernate-based DAOs, reducing typical data access operations to
single statements. A similar level of convenience is available for JDBC
in the form of Spring’s JdbcTemplate, and for iBATIS SQL Maps 1.3/2.0
in the form of SqlMapTemplate respectively SqlMapClientTemplate.


An important
characteristic of Spring is that many of
its features can be used individually, without the need to adopt an
architecture that’s completely based on Spring. Furthermore, a
Spring-managed middle tier and all the functionality it provides can be
reused in any sort of environment, be it a J2EE web application with a
Spring web MVC, Struts, WebWork or Tapestry web tier, or a standalone
application with a Swing user interface.


2. SAMPLES AND
USAGES


The Spring distribution comes with numerous sample applications. The
“-with-dependencies” download includes all third-party libraries that
are necessary for building an running them.

  • our JPetStore, adapting the iBATIS
    JPetStore with a Spring-managed middle tier and alternative
    Spring/Struts web tiers

  • Petclinic, a simple database-driven
    web application that offers alternative Hibernate/JDBC data access
    strategies

  • Countries, a web app that
    illustrates locale and theme handling, and the generation of PDF and
    Excel web views

  • Image Database, a one-screen web
    app that illustrates BLOB/CLOB handling and Velocity/FreeMarker web
    views

  • Tiles Example, demonstrating the
    use of Tiles with Spring’s web MVC framework


Spring is already used in a significant number of production
applications, including mission-critical applications. Current adopters
include a number of large banks and health care organizations in Europe
and the US. Noteworthy usages of Spring in publically visible
applications are:

  • Matt Raible’s AppFuse
    application skeleton, adopting Spring as middle tier framework with a
    Struts web tier

  • Atlassian’s new product Confluence,
    built on a Spring middle tier and a WebWork2 web tier


3. UPGRADING


Users upgrading from a Spring 1.0 milestone or release candidate,
please see the changelog;
there have
been quite a few refinements in the details. Among the changes since
1.0 RC2 are:

  • AOP support upgraded to AOP
    Alliance 1.0

  • more sophisticated handling of
    indexed and mapped properties in BeanWrapperImpl

  • new ResourceLoader interface,
    extended by the ApplicationContext interface

  • ReloadableResourceBundleMessage
    supports configurable character encodings

  • MimeMessageHelper supports
    configurable character encodings

  • JdbcTemplate has new generic
    “execute” methods and refined “query” methods

  • iBATIS SQL Maps 2.0 support
    upgraded to SQL Maps 2.0 RC1

  • added support for FreeMarker 2.3


Please note the following upgrade issues with respect to the AOP
support:

  • you have to update your
    aopalliance.jar

  • AdvisorAutoProxyCreator was renamed
    to DefaultAdvisorAutoProxyCreator

  • TransactionAttributeSourceTransactionAroundAdvisor
    was renamed to
    TransactionAttributeSourceAdvisor

  • custom Advisor implementations:
    getAdvice() now returns org.aopalliance.aop.Advice rather than Object

  • if you implemented
    org.springframework.aop.MethodAfterReturningAdvice, replace with
    AfterReturningAdvice (no change in method signature)
