Spring Security for Spring RESTful web service using the cURL tool

In this example we are using the Spring Security API classes and interfaces explicitly. We will authenticate the RESTful web service using the curl command. With the cURL tool, you can transfer data with the URL. It can be used to test the authentication. It's the same book service example which has some explicit Spring Security related API classes such as AuthenticationEntryPoint and SimpleURLAuthenticationSuccessHandler. Here, the goal is to demonstrate their internal usage in Spring Security.

Getting ready

• Implement the AuthenticationEntryPoint interface and configure in the XML file

• Extend SimpleUrlAuthenticationSuccessHandler and configure in the XML file

• Configure the Application-security.xml file

• Add security related filters to the Web.xml file

• Download the cURL tool for your operating system
