Getting ready

To run this recipe, you can use your preferred IDE and must have Java 8 and Maven installed. For this recipe, we will be executing some HTTP requests through the usage of CURL commands as we did before. Make sure you have CURL or Postman tools installed before continuing. This recipe will use Spring Security OAuth2 Framework and we will not add any database support. The source code for this recipe can be downloaded from https://github.com/PacktPublishing/OAuth-2.0-Cookbook/tree/master/Chapter02/client-credentials-server.
