Spring security loads the roles of user from user role table based on all roles assigned to user and that role is application specific.
\nBut In my project i require to assign roles to user based on instance . So when the instance is changed roles should be changed .In grails we can overide the methods of plugin. So when instance change i reauthenticate the user and overrided the “loadAuthorities ” method of spring security. So instead of fetching roles from spring security loadAuthorities method , it loads from this overided loadAuthorities method…<\/p>\n
[java]
\nclass UserRole implements Serializable {<\/p>\n
User user
\n Role role
\n BootCamp bootCamp<\/p>\n
[\/java]<\/p>\n
[java]
\nclass CustomUserDetailsService extends GormUserDetailsService {<\/p>\n
@Override
\nprotected Collection loadAuthorities(user, String username, boolean loadRoles) {
\n\t\tif (!loadRoles) {
\n\t\t\treturn []
\n\t\t}
\ndef conf = SpringSecurityUtils.securityConfig
\nString authoritiesPropertyName = conf.userLookup.authoritiesPropertyName
\nString authorityPropertyName = conf.authority.nameField
\nBootcamp bootCamp=BootCamp.get(RequestContextHolder.currentRequestAttributes().getSession()?.bootCampId))
\n User loggedInUser = User.findByEmail(username)
\n \/\/Write your query for loading roles here for ex.<\/p>\n
Collection<?> userAuthorities =UserRole.findAllByUserAndBootCamp(loggedInUser, bootCamp)?.role<\/p>\n
def authorities = userAuthorities.collect { new GrantedAuthorityImpl(it."$authorityPropertyName") }
\nauthorities ?: NO_ROLES
\n\t}
\n}
\n[\/java]<\/p>\n
for example i am reloading the role by calling this method…
\n[java]
\ndef getAuthoritiesBasedOnBootCamp() {
\n session.bootCampId = params.bootCampId
\n springSecurityService.reauthenticate(User.loggedInUser.email, "")
\n redirect(action: ‘dashBoard’)
\n }<\/p>\n
[\/java]<\/p>\n
