Spring Groovy DSL匿名內部bean與構造函數

Question

給定這兩個bean：

myMessageAdapter(MessageListenerAdapter) { bean ->
    bean.constructorArgs = [ref('jmsReceiver')]
    defaultListenerMethod = 'processMessage'
}

listenerContainer(DefaultMessageListenerContainer) {
    connectionFactory = ref('connectionFactory')
    destinationName = "MyDest"
    messageListener = ref('myMessageAdapter')
}

我想用匿名內部bean替換myMessageAdapter 。

嘗試過：

listenerContainer(DefaultMessageListenerContainer) {
    connectionFactory = ref('connectionFactory')
    destinationName = "MyDest"
    messageListener = { MessageListenerAdapter bean ->
        bean.constructorArgs = [ref('jmsReceiver')]
        defaultListenerMethod = 'processMessage'
    }
}

但是它失敗並顯示“無法在空對象上設置屬性'constructorArgs'”

如何傳遞構造函數參數？

Answer 1

當您查看BeanBuilder的源代碼和setPropertyOnBeanConfig方法時，我認為這是不可能的

Answer 2

實現此目的的方法是在bean閉包內設置類：

listenerContainer(DefaultMessageListenerContainer) {
    connectionFactory = ref('connectionFactory')
    destinationName = "MyDest"
    messageListener = { bean ->
        bean.beanClass = MessageListenerAdapter 
        bean.constructorArgs = [ref('jmsReceiver')]
        bean.defaultListenerMethod = 'processMessage'
    }
}
