Summary: The `spring-greeter` quickstart is based on the `greeter` quickstart, but differs in that it uses Spring MVC for Mapping GET and POST requests.
Target Product: WildFly
Source: https://github.com/wildfly/quickstart/

## What is it?

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

The `spring-greeter` quickstart is based on the `greeter` quickstart, but differs in that it uses Spring MVC for Mapping GET and POST requests:

- `<mvc:annotation-driven\>` configured in `src/main/webapp/WEB-INF/spring-mvc-context.xml` tells Spring to look for `@RequestMapping` in our controllers.
- Spring then routes the HTTP requests to the correct methods in `CreateController.java` and `GreetController`

Spring's XML configurations are used to get hold of the database and entity manager (via jndi) to perform transactional operations:

- `<tx:jta-transaction-manager/>` and `<tx:annotation-driven/>` are configured in `/src/main/webapp/WEB-INF/spring-business-context.xml`
- Methods in UserDaoImpl are marked as `@Transactional`, which Spring, using aspect oriented programming, surrounds with boilerplate code to make the methods transactional

When you deploy this example, two users are automatically created for you: emuster and jdoe. This data is located in the `src/main/resources/init-db.sql` file.

To test this example:

1. Enter a name in the username field and click on Greet!.
2. If you enter a username that is not in the database, you get a message No such user exists!.
3. If you enter a valid username, you get a message "Hello, " followed by the user's first and last name.
4. To create a new user, click the Add a new user link. Enter the username, first name, and last name and then click Add User. The user is added and a message displays the new user id number.
5. Click on the Greet a user! link to return to the Greet! page.

## 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 with the default profile:

       For Linux:   bin/standalone.sh
       For Windows: 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 package wildfly:deploy

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

If you do not have maven configured you can manually copy target/spring-greeter.war to WILDFLY_HOME/standalone/deployments.

## Access the application

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

## 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

Or you can manually remove the application by removing spring-greeter.war from WILDFLY_HOME/standalone/deployments

## 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
