Purpose of this sample project is to make students familiar with basic technologies they’re going to use during the Software Engineering Lab at Technical University of Dresden.
GitPod is a cloud IDE that allows you to work with a project right from your browser:
-
Click this link to open the project in GitPod.
-
Wait for the build to finish (see progress in the console view).
-
Once the website opens in the embedded preview browser, the project is ready to be worked with.

Note
|
Working on your local machine requires Java 17, and a recent Git (2.21 or better preferred) to be available on your machine.
If you miss any of those go through the steps described in Prerequisites.
Also, note that you have to run mvnw.cmd instead of ./mvnw if you run Windows by accident.

$ git clone https://github.com/st-tu-dresden/guestbook
$ cd guestbook
$ ./mvnw clean package
$ ./mvnw spring-boot:runAfter that point your browser to http://localhost:8080.
Note that Spring Boot creates a default user user with a random password printed to the console when the application starts, as described in the Spring Boot reference docs.
Download the binaries, install. Make sure the console shows something like this:
$ java -version
openjdk version "17.0.4.1" 2022-08-12
OpenJDK Runtime Environment Temurin-17.0.4.1+1 (build 17.0.4.1+1)
OpenJDK 64-Bit Server VM Temurin-17.0.4.1+1 (build 17.0.4.1+1, mixed mode)Make sure that the wrapped Maven picks up the same JDK version and that the following command shows similar output:
$ ./mvnw --version
Apache Maven 3.8.6 (84538c9988a25aec085021c365c560670ad80f63)
Maven home: /Users/martin/.m2/wrapper/dists/apache-maven-3.8.6-bin/67568434/apache-maven-3.8.6
Java version: 17.0.4.1, vendor: Eclipse Adoptium, runtime: /Library/Java/JavaVirtualMachines/temurin-17.jdk/Contents/Home
Default locale: de_DE, platform encoding: UTF-8
OS name: "mac os x", version: "12.6", arch: "aarch64", family: "mac"Download the binaries, run the installer. Verify the command line shows something like this after install:
$ git --version
git version 2.33.0Grab the latest Spring Tool Suite (plain Eclipse should work as well), run installer or unzip and run it.
Select File › Import, select Maven › Existing Maven Projects, select the folder you checked the project out into and hit Finish. This will import the project into your workspace.
In the Console view you might wanna click the Open Console button and select Maven Console to see that Maven is downloading dependencies, sources and Javadocs.
Grab the latest IntelliJ IDEA IDE (both Community Edition and Ultimate Edition will work), install it according to the instructions on their website and run it.
From the Welcome Screen, select Open. Otherwise, if you’ve already opened another project, you’ll need to select File › Open….
Now, navigate to the folder you checked the project out into (it should contain pom.xml), select it and hit Open.
When asked whether to trust and open the Maven project, proceed with Trust Project.
Now you have to wait a bit while IntelliJ and Maven work on importing the project, which includes downloading all required dependencies from the internet. All IDE activities are displayed in the status bar.
This sample application is build on top of the following technologies:
Rapid application development framework based on Spring (see below).
The de-facto standard Java application framework.
Spring module to easily build data acess layers using JPA 2.2 (Java Persistence API).
