Thespring-greeter
quickstart is based on thegreeter
quickstart, but differs in that it uses Spring MVC for MappingGET
andPOST
requests.
What is it?
The application this project produces is designed to be run on Red Hat JBoss Enterprise Application Platform 7.1 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:
-
The
mvc:annotation-driven
element configured in thesrc/main/webapp/WEB-INF/spring-mvc-context.xml
file tells Spring to look for@RequestMapping
in the controllers. -
Spring then routes the HTTP requests to the correct methods in
CreateController.java
andGreetController
Spring’s XML configurations are used to get hold of the database and entity manager (via jndi) to perform transactional operations:
-
The
tx:jta-transaction-manager
andtx:annotation-driven
elements are configured in the/src/main/webapp/WEB-INF/spring-business-context.xml
file. -
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:
-
Enter a name in the username field and click on Greet!.
-
If you enter a username that is not in the database, you get a message
No such user exists!`
. -
If you enter a valid username, you get a message "Hello, " followed by the user’s first and last name.
-
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.
-
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 Red Hat JBoss Enterprise Application Platform 7.1 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 to Build and Deploy the Quickstarts to make sure you are configured correctly for testing the quickstarts.
Use of EAP_HOME
In the following instructions, replace EAP_HOME
with the actual path to your JBoss EAP installation. The installation path is described in detail here: Use of EAP_HOME and JBOSS_HOME Variables.
Start the JBoss EAP Standalone Server
-
Open a terminal and navigate to the root of the JBoss EAP directory.
-
Start the JBoss EAP server with the default profile by typing the following command.
$ EAP_HOME/bin/standalone.sh
NoteFor Windows, use the EAP_HOME\bin\standalone.bat
script.
Build and Deploy the Quickstart
-
Make sure you start the JBoss EAP server as described above.
-
Open a terminal and navigate to the root directory of this quickstart.
-
Type the following command to build the artifacts.
$ mvn clean package wildfly:deploy
This deploys the spring-greeter/target/spring-greeter.war
to the running instance of the server.
You should see a message in the server log indicating that the archive deployed successfully.
If you do not have Maven configured you can manually copy target/spring-greeter.war
to EAP_HOME/standalone/deployments/
directory.
Access the application
The application will be running at the following URL: http://localhost:8080/spring-greeter/
Undeploy the Quickstart
When you are finished testing the quickstart, follow these steps to undeploy the archive.
-
Make sure you start the JBoss EAP server as described above.
-
Open a terminal and navigate to the root directory of this quickstart.
-
Type this command to undeploy the archive:
$ mvn wildfly:undeploy
Or you can manually remove the application by removing spring-greeter.war
from the EAP_HOME/standalone/deployments/
directory.
Run the Arquillian Functional Tests
This quickstart provides Arquillian functional tests. They are located under the functional-tests/
directory. Functional tests verify that your application behaves correctly from the user’s point of view and simulate clicking around the web page as a normal user would do.
Note
|
The Arquillian functional tests deploy the application, so make sure you undeploy the quickstart before you begin. |
Follow these steps to run the functional tests.
-
Start the JBoss EAP server as described above.
-
Build the quickstart archive.
-
Open a terminal and navigate to the root directory of this quickstart.
-
Build the quickstart archive using the following command:
$ mvn clean package
-
-
Navigate to the
functional-tests/
directory in this quickstart. -
Type the following command to run the
verify
goal with thearq-remote
profile activated.$ mvn clean verify -Parq-remote
Note
|
You can also let Arquillian manage the JBoss EAP server by using the |
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 in Red Hat JBoss Developer Studio or from Eclipse using JBoss tools. For general information about how to import a quickstart, add a JBoss EAP server, and build and deploy a quickstart, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts.
