grails - Grails Atmosphere Broadcaster 不工作

Question

我正在尝试在我的 grails 应用程序中实现气氛插件。我有以下代码

class AtmosphereService {

static transactional = true

static atmosphere = [mapping: '/atmosphere/status']

static exposes = ['jms']

@Subscriber(topic='msgevent')
def onEvent(msg) {

    def payload = msg
    if(msg instanceof Map) {
        // convert map messages to JSON
        payload = msg.encodeAsJSON()
    }

    // broadcast to the atmosphere
    broadcaster['/atmosphere/status'].broadcast(payload)
    println("jms service->  "+payload)
    /*Broadcaster brod = lookupBroadcaster(msg["id"], false)
    brod.broadcast(payload)*/

    return null
}

我还添加了 onRequest 和 onStateChange 闭包。但我得到一个“嵌套异常是 groovy.lang.MissingPropertyException：没有这样的属性：类的广播器：com.AtmosphereService”异常。我无法理解我做错了什么。有人可以帮我解决这个问题吗？谢谢
