![]() ![]() The HttpSecurity method rejects the request earlier, in a web request filter, before controller mapping has occurred. The first difference is subtle, but worth mentioning. Differentiate Between Spring Security’s and HttpSecurity In practice, using the on a controller method is very similar to using HttpSecurity pattern matchers on a specific endpoint. If access is not granted, the method is not executed, and an HTTP Unauthorized is returned. This annotation contains a Spring Expression Language (SpEL) snippet that is assessed to determine if the request should be authenticated. Method-level security is implemented by placing the on controller methods (actually one of a set of annotations available, but the most commonly used). This is also where implementation options, such as OAuth 2.0, Form Login, and HTTP Basic are exposed. The pattern matching for endpoints and fluent API exposed by HttpSecurity is great for building universal authentication policies. This method is universal and is applied to all requests. The second method, which is also the main focus of this tutorial, is to use method-level security - also known as the annotation on controller method. The first way focuses on overriding the original setting on the HttpSecurity object by building WebSecurit圜onfigurerAdapter and using the fluent API. ![]() In this tutorial, we’ll look into a couple of methods for implementing authentication and authorization in Spring Boot using Spring Security. ![]()
