spring security 설정 및 oauth 초기화

grails s2-quickstart com.shuiky User Role

grails s2-init-oauth com.shuiky OAuthID

Config.groovy에 추가하시고 secret과 key는 각 oauth provider에게 발급받으시고 알맞게 수정해주세요

def appName = grails.util.Metadata.current.'app.name'

def baseURL = grails.serverURL ?: "http://localhost:${System.getProperty('server.port', '8080')}/${appName}"

oauth {

debug = true

providers {

facebook {

api = org.scribe.builder.api.FacebookApi

key = 'oauth_facebook_key'

secret = 'oauth_facebook_secret'

successUri = '/oauth/facebook/success'

failureUri = '/oauth/facebook/failure'

callback = "${baseURL}/oauth/facebook/callback"

}

twitter {

api = org.scribe.builder.api.TwitterApi

key = 'oauth_twitter_key'

secret = 'oauth_twitter_secret'

successUri = '/oauth/twitter/success'

failureUri = '/oauth/twitter/failure'

callback = "${baseURL}/oauth/twitter/callback"

}

linkedin {

api = org.scribe.builder.api.LinkedInApi

key = 'oauth_linkedin_key'

secret = 'oauth_linkedin_secret'

successUri = '/oauth/linkedin/success'

failureUri = '/oauth/linkedin/failure'

callback = "${baseURL}/oauth/linkedin/callback"

}

// for Google OAuth 2.0

google {

api = org.grails.plugin.springsecurity.oauth.GoogleApi20

key = 'oauth_google_key'

secret = 'oauth_google_secret'

successUri = '/oauth/google/success'

failureUri = '/oauth/google/failure'

callback = "${baseURL}/oauth/google/callback"

scope = 'https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email'

}

}

}

grails.plugin.springsecurity.controllerAnnotations.staticRules = [

....

'/oauth':                              ['permitAll'],

....

]

User.groovy 에 다음을 추가한다.

static hasMany = [oAuthIDs: OAuthID]
