WAFFLE framework analysis: A single -point login in the Java library is implemented in the Java library

WAFFLE framework analysis: realize single -point login in the Java class library WAFFLE is a Java-based open source library that provides support for realizing the Single Sign-on function in the Windows operating system.One -point login is an identity authentication technology that allows users to access multiple related applications only once to access multiple related applications. The WAFFLE framework uses Windows integrated login (Integrated Windows Authentication) technology. When interacting with the web server, it automatically obtains user credentials, so as to realize the identity verification process that does not need to enter the user name and password again.It provides the function of seamless integration with Java Servlet, and supports commonly used Web containers, such as Apache Tomcat and Jetty. The following is a simple example to show how to use the Waffle framework to implement a single login function: import waffle.servlet.NegotiateSecurityFilter; public class SingleSignOnExample { public static void main(String[] args) { // Create NegotiateSecurityFilter instance NegotiateSecurityFilter securityFilter = new NegotiateSecurityFilter(); // Import related configuration (the following is an example configuration) securityFilter.setAllowGuestLogin(false); securityFilter.setSecurityFilterProviders("waffle.servlet.spi.BasicSecurityFilterProvider"); // Initialize the filter securityFilter.init(null); // Assume that there is a service that requires authentication YourAuthenticatedServlet servlet = new YourAuthenticatedServlet(); // Create an analog object of HTTPSERVLETREQUEST and HTTPSERVLESPONSE MockHttpServletRequest request = new MockHttpServletRequest(); MockHttpServletResponse response = new MockHttpServletResponse(); // Simulation user request servlet.service(request, response); // Get user identity information String username = (String) request.getAttribute("waffle.servlet.request.username"); // Print user identity information System.out.println("User: " + username); } } In the above examples, first create a NegotiatedSecurityFilter instance and import some related configurations.Then initialize the filter.Then, create a Servlet that needs to be verified (represented by YourauthenticatedServlet).Create an analog object of HTTPSERVLETREQUST and HTTPSERVLESPONSE and simulate user requests.Finally, obtain the user's identity information by obtaining the attributes in the HTTPSERVLETREQUEST object. Using the Waffle framework, you can easily implement a single login function in the Java application.It provides seamless integration with Windows integrated login technology, simplifies the process of user identity verification, and improves the user experience.I hope this article can help you understand the basic principles and usage methods of the Waffle framework.
