# About this project
2+
This project contains examples from the [Spring Data with Spring Security](http://www.baeldung.com/spring-data-with-spring-security) article from Baeldung.
3+
4+
# Running the project
5+
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:
6+
* Run the `main` method from `SpringDataRestApplication`
7+
* Use the Maven Spring Boot plugin: `mvn spring-boot:run`
8+
* Package the application as a JAR and run it using `java -jar spring-data-spring-security.jar`
9+
10+
# Viewing the running application
11+
To view the running application, visit [http://localhost:8080](http://localhost:8080) in your browser
