如何在springboot中使用html模板使用JWT认证？

Question

For a few days I have begun to learn to work with springboot and particularly with spring security for user authentication, for this I have decided to make an apirest using a system in which the user authenticates and can access the service according to their specific role.

I used this post as a guide: https://grokonez.com/spring-framework/spring-boot/spring-security-jwt-authentication-postgresql-restapis-springboot-spring-mvc-spring-jpa

in which it is used Spring Security JWT Authentication PostgreSQL - RestAPIs SpringBoot Spring MVC Spring JPA

I would like to integrate it with html templates, perhaps using thymeleaf dependency in pom.xml, bootstrap and jquery (not with Agular React or Vuejs since this is the way I should do it in my work due to a compatibility problem)

I have also seen several tutorials where thymeleaf is used but does not include JWT Authentication

Could someone tell me how to complete this exercise? Any tutorial explaining how to do it?

Answer 1

I assume the anotations like @PreAuthorize("hasRole('USER')") from your link should work the same for thymeleaf endpoints.

eg.:

@Controller
public class ThymeleafController {

    @GetMapping("/hello")
    @PreAuthorize("hasRole('USER')")
    public String hello() {
        return "thymeleaf-template";
    }
}
