Web SecurityConfigurerAdapter

Web SecurityConfigurerAdapter is a component in Spring Security, a framework for securing Java web applications. It simplifies the process of configuring security settings, such as user authentication and authorization. By extending this adapter, developers can customize security rules, like which users can access certain parts of the application, without starting from scratch. It provides built-in methods to easily set up security features, making it more manageable to protect sensitive information and ensure that only authorized users can access specific resources within a web application.
