=== 1. Declare mode in Config.groovy ===
 
 
// Multi Tenant
 
tenant {
 
// multiTenant is the default
 
// do "grails create-dns-map" when changing tenantDomains
 
// this stroes the dns/tenant mappings into the database
 
resolver.request.dns.type = "db"
 
}
 
 
=== 2. Declare Tenant Class ===
 
 
This class should be a top level class. E.g. "Organisation" hasMany "Users".
 
 
import grails.plugin.multitenant.core.groovy.compiler.MultiTenant;
 
@MultiTenant
 
class Organisation {
 
 
[...]
 
 
=== 3. Create a TenantMap domain class  ===
 
This is achieved by using the command
 
grails create-'''domain'''-map
 
 
This creates a domain class with the name '''Domain'''TenantMap.groovy
 
 
=== 4. BootStrap.groovy ===
 
 
import grails.plugin.multitenant.core.util.TenantUtils
 
import org.codehaus.groovy.grails.commons.ConfigurationHolder
 
 
// from domain -> tenant ...
 
import tenant.DomainTenantMap
 
 
class BootStrap {
 
 
    def springSecurityService
 
    def demoDataService
 
 
    def init = { servletContext ->
 
 
 
def domainName = ConfigurationHolder.config.grails.tenantDomain
 
        if  {
 
          DomainTenantMap.findByName('website')
 
        } else {
 
          new DomainTenantMap(  name:'website',
 
                                domainName:domainName,
 
                                mappedTenantId:1).save(flush:true);
 
        }

Spring Security

s2-quickstart

grails s2quickstart  your.package SecUser SecRole

creates two domain classes and corresponding controllers.

Integrade domain classes

class MyDomainClass extends SecUser {

    [...]
}

BootStrap.groovy

class BootStrap {

  def dpringSecurityService

  def init = {
    
      def userRole = SecRole.findByAuthority("ROLE_USER") ?: new SecRole(authority: "ROLE_USER").save()
      def adminRole = SecRole.findByAuthority("ROLE_ADMIN") ?: new SecRole(authority: "ROLE_ADMIN").save()
      [...]
  }
  
  def users = User.list() ?: []
  if (!users) {
     def user = new User(
         [...]
         password: springSecurityService.enodePassord("myPass")
         enabled = true
     )
  }

  SecUserSecRole.create user, userRole
 
}

Annotate the controller actions

import grails.plugins.springsecurity.Secured

class DomainClassController {

   @Secured(['ROLE_USER'])
   def myAction = {
       [...]
   }

}

Create a currentUser() method in the controller

class DomainClassController {

   @Secured(['ROLE_USER'])
   def myAction = {
       def currentUser = currentuser();
       [...]

   } 
  
       [...]
   private currentUser() {
        User.get(springSecurityService.principal.id)
