The first step is to create a custom interceptor class. This class should inherit from Step 2 involves configuring the For example, if a login request does not start with "sys", it should be blocked by the interceptor. This can be implemented in the Timer,Electronic Timer, Waterproof Timer, Countdown Timer NINGBO COWELL ELECTRONICS & TECHNOLOGY CO., LTD , https://www.cowellsocket.comHandlerInterceptorAdapter, and you need to override the preHandle() method. This method allows you to perform checks before the request is processed, such as validating user authentication or checking access rights.springmvc.xml file to register your custom interceptor. In this configuration, you define the interceptor's properties, such as the path it should apply to and any excluded URLs. This ensures that the interceptor is only triggered for specific requests, improving performance and control over the flow of your application.preHandle() method by checking the request URI and returning false if the condition is not met, which prevents the request from proceeding further. This approach helps in securing certain parts of your web application and ensuring only authorized users can access them.
