z2-Environment

h1. A basic Spring with Z2 modularity sample

The sample contained in the repository "z2-samples.spring-basic":http://redmine.z2-environment.net/projects/z2-samples/repository/z2-samples-spring-basic is a clean room example on how to use the Spring integration features described in [[how_to_spring]].

There is no further pre-requisite to running this sample, and you may proceed as described in [[How to run a sample]]. Here's the really fast version:

<pre><code class="ruby">

mkdir install

cd install 

git clone -b master http://git.z2-environment.net/z2-base.core

git clone -b master http://git.z2-environment.net/z2-samples.spring-basic

# on Linux / Mac OS:

cd z2-base.core/run/bin

./gui.sh

# on Windows:

cd z2-base.core\run\bin

gui.bat

</code></pre>

There are two modules contained in this sample:

h2. com.zfabrik.samples.spring-basic.services

This module has a classpath defined "applicationContext":http://redmine.z2-environment.net/projects/z2-samples/repository/z2-samples-spring-basic/revisions/master/entry/com.zfabrik.samples.spring-basic.services/java/src.impl/META-INF/applicationContext.xml and exposes an annotation defined bean "ComputationServiceImpl":http://redmine.z2-environment.net/projects/z2-samples/repository/z2-samples-spring-basic/revisions/master/entry/com.zfabrik.samples.spring-basic.services/java/src.impl/com/zfabrik/samples/impl/services/ComputationServiceImpl.java bean from it as a service to be consumed from another module: The *computations* bean.

h2. com.zfabrik.samples.spring-basic.frontend

This module has a Web application with an application context defined in WEB-INF/applicationContext. It uses Spring AspectJ based annotation driven configuration to inject dependencies into instances of "ControllerServlet":http://redmine.z2-environment.net/projects/z2-samples/repository/z2-samples-spring-basic/revisions/master/entry/com.zfabrik.samples.spring-basic.frontend/java/src.impl/com/zfabrik/samples/impl/frontend/ControllerServlet.java.

It's "application context":http://redmine.z2-environment.net/projects/z2-samples/repository/z2-samples-spring-basic/revisions/master/entry/com.zfabrik.samples.spring-basic.frontend/web/WebContent/WEB-INF/applicationContext.xml imports the *computations* service from the other module above.

h2. Finally

Open a browser and navigate to http://localhost:8080/frontend to verify you get this:
