# About this project
This project contains examples from the [Spring Data with Spring Security](http://www.baeldung.com/spring-data-with-spring-security) article from Baeldung.
# Running the project
The application uses [Spring Boot](http://projects.spring.io/spring-boot/), so it is easy to run. You can start it any of a few ways:
* Run the `main` method from `SpringDataRestApplication`
* Use the Maven Spring Boot plugin: `mvn spring-boot:run`
* Package the application as a JAR and run it using `java -jar spring-data-spring-security.jar`
# Viewing the running application
To view the running application, visit [http://localhost:8080](http://localhost:8080) in your browser
