How can I implement role-based access control in Spring Boot?
You can implement role-based access control in Spring Boot using Spring Security. First, add the Spring Security dependency to your project.
What are the key annotations I need to use?
You will primarily use @PreAuthorize
, @Secured
, and @RolesAllowed
annotations to secure your methods based on roles.
Can you give me an example of how to use @PreAuthorize?
Sure! You can annotate a method like this: @PreAuthorize("hasRole('ADMIN')")
to restrict access to users with the ADMIN role.
What if I want to customize the authentication process?
You can create a custom UserDetailsService and override the loadUserByUsername
method to customize how users are authenticated.
