the "service provider" to provide services, in fact, there is no authorization problem.Spring Security Introduction:Spring Security is a framework that focuses on providing authentication and authorization for Java applications, filtering requests for URLs using the servlet filter internally, and doing some security processing before the application processes the request.

can be processed similarly. Of course, we certainly won't do this in practice, and Spring boot certainly has a better solution. However, although this method is a bit stupid, it is indeed the most essential thing. No matter how convenient the framework can help us deal with such problems, but aside from the framework, we still need to be able to write a web proj
