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)

-== Multi Tenant ==
-An introduction on the concept of multitenant can be found at:
-* [http://en.wikipedia.org/wiki/Multitenancy http://en.wikipedia.org/wiki/Multitenancy]
-* [http://www.itwissen.info/definition/lexikon/Multi-Tenancy-Architektur-multitenancy-architecture.html It-Wissen Multitenancy]
-Documentation
-* [http://multi-tenant.github.com/grails-multi-tenant-core/guide/ http://multi-tenant.github.com/grails-multi-tenant-core/guide/]
-=== 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"
- }
-Later on you can use ''<nowiki>tenant[dot]</nowiki>'' to refer to the TenantMap domain class (see later on).
-=== 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-dns-map
-This automatically creates a domain class with the name '''''Domain'''TenantMap.groovy''.
- package tenant
- /**
-  * Maps domain name to tenantId
-  */
- class DomainTenantMap {
-   String domainName
-   Integer mappedTenantId
-   String name
-   static constraints = {}
- }
-This class maps to a database table ''domain_tenant_map''.
-=== 4. Build a MultiTenant environment in BootStrap.groovy ===
-Tenants (e.g. organisations) are created by instantiating a new tenantDomain ConfigurationHolder.
- '''import grails.plugin.multitenant.core.util.TenantUtils'''
- '''import org.codehaus.groovy.grails.commons.ConfigurationHolder'''
- '''import tenant.DomainTenantMap''' // was created with grails create-domain-map
- class BootStrap {
-    def init = { servletContext ->
-        def domainName = ConfigurationHolder.config.grails.'''tenantDomain'''
-        if  {
-           '''DomainTenantMap.findByName('myweb1')'''
-        } else {
-           new DomainTenantMap(
-                      '''name:'myweb1'''',
-                      '''domainName:domainName''',
-                      '''mappedTenantId:1''').save(flush:true);
-        }
-The property ''domainName'' refers to the correspondent field in the database ''domain_name''.
-The property ''mappedtenantId '' to the field name.
- mysql> select * from domain_tenant_map;
