Spring by Example Update (1.1)

Almost all examples have been upgraded to Spring 3.0 (except for the Aspect LTW example, GWT ones, and OSGi ones). Also a new Grails example has been added.

The web examples in particular have all been upgraded (except for GWT/OSGi) to use the new Spring MVC Namespace. Keith Donald, from SpringSource, wrote a great blog going over some of the new Spring MVC simplifications in MVC Simplifications in Spring 3.0. All the webapps were updated to use Spring MVC best practices as much as possible, except their URLs aren't currently RESTful. That will be changed as soon as soon as possible.

All modules have been upgraded to Spring 3.0 and Maven group and artifact IDs have been changed to follow Spring naming conventions (ex: custom-thread-scope --> org.springbyexample.threadscope).

The Spring 2.5.x version of the site and all examples are still available. It's available at Spring by Example 2.5.x, which is version 1.0.3.

Spring by Example Update (1.03)

Two new examples were added. One is the Simple Flex Webapp and the other is Simple Spring Integration. Also the setup in the appendix was updated to have a section configuring SpringSource Tool Suite. Besides getting extra features like tutorials, tips when using Spring, and access to the Spring knowledge base for diagnosing stack traces, you also get a reduced installation since it comes with other plugins like for AspectJ and Maven.

The Simple Flex Webapp, which is based on Simple Spring MVC Form Annotation Configuration Webapp but replaces the HTML search page with a Flex application. It uses Spring BlazeDS Integration (verson 1.0.0.RC2) for remoting. The Flex app also has logging, internationalization in sync with the server side locale, and uses the MVC framework Cairngorm.

Simple Spring Integration uses Spring Integration to process a book order and appropriately route the message depending on if it's a pickup from the store or it should be delivered.

Spring by Example Update (1.02)

Spring by Example Utils' HttpClientTemplate, HttpClientOxmTemplate, and SolrOxmClient are used for making different Apache Solr client requests. Solr provides an XML based API over HTTP to the Apache Lucene search engine. Spring OXM is used for marshalling and unmarshalling requests using a custom marshaller made with dom4j.

The SolrOxmClient was added to the Spring by Example Utils module. The SolrOxmClient provides for easier client communication with Apache Solr. It marshalls/unmarshalls searches and updates to and from a JavaBean. It also allows calls to commit, rollback, and optimize. It is built on top of HttpClientTemplate and HttpClientOxmTemplate.

Spring by Example Update (1.01)

A preface, introduction to Inversion of Control (IoC) and Dependency Injection (DI), and basic XML configuration in Spring were added to the beginning of examples.

Enhancements to Valang based on Spring Modules Validation Version 0.9 was added to the module library. When changes are complete, the code will be offered back to the Spring Modules project. There are a number of enhancements to the Valang part of the project. A few key enhancements are where clause support, enum support, and a number of performance enhancements (such as bytecode generation). Currently none of the enhancements were added to the custom JSP tag that generates JavaScript.

Also the 'Simple Spring MVC Form Annotation Configuration Webapp' was updated to follow the best practices for Spring MVC annotation based configuration presented by Rossen Stoyanchev at SpringOne. Rossen along with Keith Donald and the rest of the web team helped put together what they consider best practices for using Spring MVC annotations based on their experience and interaction with many use case scenarios from Spring users. Thanks to Rossen Stoyanchev for helping with this. The example was also updated to use JPA.

Spring by Example Update (0.98-0.99)

The Spring by Example 0.98 update added a Spring dm Server example for a very simple Spring MVC application, and the 0.99 update added a JMS example sending messages with a JMS template and receiving them with a JMS listener.
