 # spring-security-jwt-guide
 
+## Introduce
+
+[Spring Security](https://spring.io/projects/spring-security )  is a very powerful framework in the Spring family for authentication and permission control, and we can easily extend it to meet our current system security requirements.
+
+However, compared with some other technologies such as JPA, Spring Security is more difficult to get started. Many people can hardly write a Demo independently after reading video or sending documents, so they may give up learning this thing later.
+
+Spring Security, a powerful Security authentication framework, has been used in the induction training practical project when I first came to the company and the projects I am working on now. It can be seen that this framework is a good choice in the field of authentication and permission authentication. I am not familiar with Spring Security because I did not make this part of the module of the previous project by myself. So I took the time to learn this part of knowledge and implemented a simple Demo. This Demo mainly USES **Spring Security** and **Spring Boot**, and all the dependencies adopt the latest stable version. Beyond the initial project, the JPA technology was also used. The code structure of the project is as follows (chrome plug-in: octree), which is relatively clear as a whole. Due to my limited ability and time, there must be a lot of areas that can be optimized. Interested friends can improve it together.
