grails - Facebook Connect插件和Grails问题

Question

不确定如何开始解决此问题。我遵循了此页面上的确切说明-http://www.grails.org/Facebook+Connect+Plugin
此页面上的说明是否正确？或缺少什么？
这个插件会被其他东西抛弃吗？不知道Spring Social适合什么地方，或者甚至还可以投入生产。

任何人都可以使用插件复制此问题吗？和示例代码？

这似乎是插件中的错误。我现在面临着同样的问题。这是一个临时解决方法:
转到FacebookConnectService并修改afterPropertiesSet()方法，如下所示:

void afterPropertiesSet() {
    def config
    try {
        config = Class.forName("FacebookConnectConfig").newInstance()
        facebookConnectConfig = new ConfigSlurper().parse(config.getClass()) 
    } catch(ClassNotFoundException e) { 
        // no compiled class exists for the config, we must be running the Grails built-in web server 
        GroovyClassLoader loader = new GroovyClassLoader(getClass().getClassLoader()) 
        Class clazz = loader.parseClass(new File("grails-app/conf/FacebookConnectConfig.groovy")) 
        facebookConnectConfig = new ConfigSlurper().parse(clazz) 
    }
}
