Securing RESTful Web Service with Basic Authentication

1. Introduction

We have been through several web service tutorials and particularly on creating RESTful Web Service with Spring. In this tutorial, we will check out how we can secure our RESTful Web Service with Basic Authentication using Spring Security.

2. Implementation

Once the RESTful Web Service is ready, add the following to the existing pom dependencies –

pom.xml

Make sure the web.xml has the Spring Security filter configured. If not, add the following –


web.xml

In the spring context XML, add the following –

mvc-dispatcher-servlet.xml

Note that we have added a sample user, with credentials user/123, instead of which we could easily configure an LDAP authentication in place for advanced implementations.

<security:http-basic /> is something that’s more important here to enable basic authentication. Read more about Spring Security Basic Authentication here
