Spring MVC 3.1 - Implement CRUD with Spring Data Neo4j (Part 5)

Review

We have just completed our application! In the previous sections, we have discussed the functional specs, created the Java classes, declared the configuration files, and wrote the HTML files. In this section, we will build and run the application using Maven, and show how to import the project in Eclipse.

Part 1: Introduction and Functional Specs
Part 2: Java classes
Part 3: XML configuration
Part 4: HTML (with AJAX)
Part 5: Running the Application

Running the Application

Access the source code

To download the source code, please visit the project's Github repository (click here)

Preparing the data source

• You don't need to run a separate Neo4j server because it will start simultaneously with the application.
• There's no need to populate the database.
• Due to some issues with the initialization service, I have decided to deactivate the service (though it's included in the source code for reference).

Building with Maven

1. Ensure Maven is installed
2. Open a command window (Windows) or a terminal (Linux/Mac)
3. Run the following command:
   

   mvn tomcat:run

4. You should see the following output:
   

   [INFO] Scanning for projects...
   [INFO] Searching repository for plugin with prefix: 'tomcat'.
   [INFO] artifact org.codehaus.mojo:tomcat-maven-plugin: checking for updates from central

Note: If the project will not build due to missing repositories, please enable the repositories section in the pom.xml!

Access the Entry page

1. Follow the steps with Building with Maven
2. Open a browser
3. Enter the following URL (8080 is the default port for Tomcat):
   

   http://localhost:8080/spring-neo4j-tutorial/

Import the project in Eclipse

1. Ensure Maven is installed
2. Open a command window (Windows) or a terminal (Linux/Mac)
3. Run the following command:
   

   mvn eclipse:eclipse -Dwtpversion=2.0

4. You should see the following output:
   

   [INFO] Scanning for projects...
   [INFO] Searching repository for plugin with prefix: 'eclipse'.
   [INFO] org.apache.maven.plugins: checking for updates from central

   This command will add the following files to your project:
   

   .classpath
   .project
   .settings
   target

   You may have to enable "show hidden files" in your file explorer to view them
   
5. Open Eclipse and import the project

Conclusion

That's it! We've have successfully completed our Spring MVC 3.1 web application. We've learned how to integrate Neo4j using the Spring Data Neo4j framework, and studied how to map our domain objects to the Neo4j graph. We've only explored the basics of Neo4j, but I hope that this simple tutorial will provide a good start.

I hope you've enjoyed this tutorial. Don't forget to check my other tutorials at the Tutorials section.
