Spring Security Grails插件授权

Question

Background

I'm using the Spring Security Grails plugin. Because my User and Role classes are not GORM objects, I I've replaced the UserDetailsService provided by the plugin with my own implementation:

class CustomUserDetailsService implements UserDetailsService {

    static transactional = false
    private static final log = LogFactory.getLog(this)

    @Autowired
    private UserManager userManager

    @Autowired
    private RoleManager roleManager

    UserDetails loadUserByUsername(String username) {
        User user = userManager.getUserByEmail(username)
        UserDetails userDetails = new UserAdapter(user, roleManager)

        log.debug "user '$username' has roles: ${userDetails.authorities?.authority}"
        userDetails       
    }
}

Problem

When I login, I see the following message is logged from CustomUserDetailsService.loadUserByUsername()

user 'a5511120@nepwk.com' has roles: [USER]

So it seems that the user has been assigned the USER role. However, when I then try and access an action of this controller:

@Secured(['ROLE_USER', 'ROLE_ADMINISTRATOR'])
class MyProfileController {
    def someAction = { // impl omitted }
}

I get bounced to the access denied page. I'm pretty sure that the user is logged in, because the access denied page contains markup such as

<sec:ifLoggedIn>
  protected content
</sec:ifLoggedIn>

and the protected content is displayed. So it seems that somehow the USER role is not associated with the current user, when the controller authorisation is performed. The log message suggests that the UserDetailsService is OK.

Solution

The solution is to make sure that the role names in the domain class/database begin with "ROLE_", as per the annotation parameters.
