资源说明：Examples of Spring Integration in OSGi environment
h1. About this example
This example demonstrates *Spring Integration* features running in an OSGi environment.
!http://nilshartmann.net/spring-integration-example/chains.png!
h1. Environment
The example uses the following frameworks:
* Equinox 3.6.1
* Spring 3.0.5
* Spring Integration 2.0.1
* Spring Dynamic Modules (DM) 2.0.0.M1
* EclipseLink 2.x
h1. Running the example
This section describes how to run the examples directly from Eclipse.
h2. Setup the Eclipse workspace
# Clone the Git-Repository to your local harddisc
# Import all projects into your Eclipse installation (File -> Import -> Existing projects...)
# Set the target platform to make projects compile: Open *order.target* from the module *target.platform* using the "Target Editor". Click on "Set as Target Platform". Now all projects should compile. Your ready to execute the example.
h2. Starting the dependent application
The application depends on a running JMS server, a database, a FTP and a Mail server. The former three are included inside the project *nh.examples.springintegration.runtime*. Before you start the example application you have to launch the servers. For each there is a prepared launch configuration available from the Launch Configuration menu (JMS server and database):
!http://nilshartmann.net/spring-integration-example/howto/launch-config.png!
The FTP server can be started via an External Tools launch configuration:
!http://nilshartmann.net/spring-integration-example/howto/external-launch-config.png!
After you've started the server processes you have to configure the mail server.
h3. Configuring the Mail server
The example server needs a mail server. You can configure an existing server in the file *shipping-ctx.properties_template* in *nh.examples.springintegration.order.shipping/META-INF/spring*. Please rename (or copy) this file to *shipping-ctx.properties* and set you E-Mail server host, user, password etc.
h2. Start the server
Now it's time to start the OSGi-based server. You can launch it with the *Order OSGi Server* Launch Configuration from the Run menu. It will start Equinox and deploy all needed bundles from the target platform and from the workspace.
When the server has been started please make sure that all required Spring application contexts have been successfully configured. To do so, execute the command *lc* on the Equinox console:
!http://nilshartmann.net/spring-integration-example/howto/equinox-lc.png!
You should see four application contexts (resp their containing bundles) that are in state REFRESHED.
(Note that the state displayed ("REFRESHED") is the state of an *application context*, it's not the *bundle* state!)
h2. Run the client
The example comes with a very simple swing client that can be used to view, create, edit and submit orders.
To start the client use the *Swing Client* launch configuration. Two windows are displayed:
* The *Event Browser*. This window display all (business) events that are published on the server.
* The *Order Overview*. In this window all orders that exist in the server's database are displayed.
The following screenshot shows an example:
!http://nilshartmann.net/spring-integration-example/howto/client-1.png!
Note that the whole communication between client and server is done via JMS.
h3. Add a new Order
To add a new Order press the *Add order* button in the *Order overview* window. In the next screen
you have to enter a (fictional) customer name and an e-mail (note that the e-mail-address you enter is used to send a real email, so you should either use your own e-mail to prevent spaming someone else).
After pressing OK a JMS request is sent to the server and your Order is created. You can see a confirmation in the Event Viewer, where a new *OrderCreatedEvent* should be shown.
h3. Add something to your Order
Now you can edit your order by opening the context menu with a right click on a line in the table. From the context menu choose *Edit order*:
!http://nilshartmann.net/spring-integration-example/howto/edit-order.png!
A new window opens that allows you to add Line items to your order by pressing "Add Line Item". You can fill in whatever you want in the dialog that opens:
!http://nilshartmann.net/spring-integration-example/howto/add-line-item.png!
Note that after you click OK the *Edit order*-window does not get updated (thats not implemented yet). But you can see that something happend on the server by inspecting the *Event Browser* where *LineItemAdded*-events should have been received.
h3. Submitting your Order
Now submit your order by choosing *Submit order* from the Overview's context menu. An appropriate *SubmitOrderCommand* is sent to the server, where your Order gets "processed". Processing the order
leads to an Event (*OrderSubmitted*) that is received by a fictional "shipping" component. This component:
* send a confirmation e-mail to your e-mail account
* put a "shipping request" on the ftp server (have a look at nh.examples.springintegration.runtime/data/ftp/home)
Now press "Refresh" in the *Order Overview* window. You order should now have the state *SUBMITTED*.
You successfully have processed your first order ;-)
