我无法在grails中显示来自不同域的数据

// grails-app/conf/spring/resources.groovy

import org.springframework.security.web.csrf.CsrfTokenRepository
import org.springframework.security.web.csrf.HttpSessionCsrfTokenRepository

beans = {
    corsFilter(org.springframework.web.filter.CorsFilter) {
        CorsConfiguration corsConfig = new CorsConfiguration()
        corsConfig.allowedOrigins = ["http://example.com"]
        corsConfig.allowedMethods = ["GET", "POST"]
        corsConfig.allowedHeaders = ["Origin", "Content-Type", "Accept"]
        source = { corsConfig }
    }

    csrfTokenRepository(CsrfTokenRepository) {
        HttpSessionCsrfTokenRepository csrfTokenRepository = new HttpSessionCsrfTokenRepository()
        csrfTokenRepository.setHeaderName("X-XSRF-TOKEN")
        delegate = csrfTokenRepository
    }
}
