Summary: The `spring-kitchensink-matrixvariables` quickstart showcases Spring 4.x's support for Matrix Variables in URLs that was introduced in Spring 3.2.
Target Product: WildFly

## What is it?

This is your project! It is a sample, deployable Maven 3 project to help you get your foot in the door developing with Java EE 7 and Spring in WildFly Application Server 11 or later.

This project is setup to allow you to create a compliant Java EE 7 application using JSP, JPA and Spring 4.x. It includes a persistence unit and some sample persistence and transaction code to introduce you to database access in enterprise Java:

- This module showcases Spring 4.x's support for Matrix Variables in urls introduced in Spring 3.2.

- In `jboss-as-spring-mvc-context.xml` `<context:component-scan base-package="org.jboss.as.quickstarts.kitchensink.spring.matrixvariables.controller"/>` and `<mvc:annotation-driven/>` are used to register both the non-rest and rest controllers. This is how it works normally, however if we want to use `@MatrixVariable` we must set the `removeSemicolonContent` property of `RequestMappingHandlerMapping` to `false`. This has been done by commenting out `<mvc:annotation-driven/>` and using `<bean class='org.jboss.as.quickstarts.kitchensink.spring.matrixvariables.config.WebConfig'/>`. Then in the WebConfig class we set the `removeSemicolonContent` property to `false`.

- The controllers map the respective urls to methods using `@RequestMapping(url)`.

- To return JSON, the rest controller uses `@ResponseBody`.

- The datasource and entitymanager are retrieved via JNDI.

- An additional form is added in `index.jsp` which allows the user to filter the member list. The form is submitted in the url form: `/filter;n=Name;e=Email`.

- Using `@MatrixVariable` the controller method captures the values and feeds them to the memberDao.

## System Requirements

The application this project produces is designed to be run on WildFly Application Server 11 or later.

All you need to build this project is Java 8.0 (Java SDK 1.8) or later and Maven 3.3.1 or later. See Configure Maven for WildFly 11 to make sure you are configured correctly for testing the quickstarts.

## Start the Server

1. Open a command line and navigate to the root of the WildFly directory.
2. The following shows the command line to start the server:

       For Linux:   WILDFLY_HOME/bin/standalone.sh
       For Windows: WILDFLY_HOME\bin\standalone.bat

## Build and Deploy the Quickstart

1. Make sure you have started the WildFly server as described above.
2. Open a command line and navigate to the root directory of this quickstart.
3. Type this command to build and deploy the archive:

       mvn clean install wildfly:deploy

4. This will deploy `target/spring-kitchensink-matrixvariables.war` to the running instance of the server.

## Access the Application

The application will be running at the following URL: http://localhost:8080/spring-kitchensink-matrixvariables/.

## Undeploy the Archive

1. Make sure you have started the WildFly server as described above.
2. Open a command line and navigate to the root directory of this quickstart.
3. When you are finished testing, type this command to undeploy the archive:

       mvn wildfly:undeploy

## Run the Arquillian Functional Tests

This quickstart provides Arquillian functional tests as well. They are located in the functional-tests/ subdirectory under the root directory of this quickstart. Functional tests verify that your application behaves correctly from the user's point of view. The tests open a browser instance, simulate clicking around the page as a normal user would do, and then close the browser instance.

To run these tests, you must build the main project as described above.

1. Open a command line and navigate to the root directory of this quickstart.
2. Build the quickstart WAR using the following command:

       mvn clean package

3. Navigate to the functional-tests/ directory in this quickstart.

4. If you have a running instance of the WildFly server, as described above, run the remote tests by typing the following command:

       mvn clean verify -Parq-remote

5. If you prefer to run the functional tests using managed instance of the WildFly server, meaning the tests will start the server for you, type the following command:

       mvn clean verify -Parq-managed

## Run the Quickstart in Red Hat JBoss Developer Studio or Eclipse

You can also start the server and deploy the quickstarts or run the Arquillian tests from Eclipse using JBoss tools. For general information about how to import a quickstart, add a WildFly server, and build and deploy a quickstart, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts.

## Debug the Application

If you want to debug the source code or look at the Javadocs of any library in the project, run either of the following commands to pull them into your local repository. The IDE should then detect them.

        mvn dependency:sources
        mvn dependency:resolve -Dclassifier=javadoc
