Multi Tenant
An introduction on the concept of multitenant can be found at:
Documentation
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 tenant[dot] 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 DomainTenantMap.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.

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)
