ApplicationConfiguration.groovy

package com.danveloper.reactor.config

reactor {
    social {
        twitter {
            consumerKey = "ABCD"
            consumerSecret = "EFGH"
            accessToken = "IJKL"
            accessTokenSecret = "MNOP"
        }
    }
}

SpringConfiguration.groovy

@Configuration
class SpringConfiguration {
    @Bean
    public static PropertyPlaceholderConfigurer props() {
        def config = new ConfigSlurper().parse(ApplicationConfiguration)
        def configurer = new PropertyPlaceholderConfigurer()
        configurer.setProperties(config.toProperties())
        configurer
    }

    @Bean
    public TemplateFactory templateFactory() {
        new TemplateFactory()
    }
}

TemplateFactory.groovy

@Service
class TemplateFactory {
    @Value('${reactor.social.twitter.consumerKey}')
    private String consumerKey

    @Value('${reactor.social.twitter.consumerSecret}')
    private String consumerSecret

    @Value('${reactor.social.twitter.accessToken}')
    private String accessToken

    @Value('${reactor.social.twitter.accessTokenSecret}')
    private String accessTokenSecret

    TwitterTemplate createTwitterTemplate() {
        new TwitterTemplate(consumerKey, consumerSecret, accessToken, accessTokenSecret)
    }
