审核Adobe CQ 561中的节点

我想获得CQ561中特定节点上的更改列表。

---

我还需要更改列表中以前的值和修改后的值。

AFAIK没有编码就无法获得该功能。
您可以使用javax.JCR.observation.ObservationManager观察JCR节点及其属性 创建一个JCREventListener，并在ObservationManager中注册它，可以从JCR会话中检索它。有关更多详细信息，请参阅。
但是javax.jcr.observation.Event不包含前面的值，因此您必须自己组织此逻辑

    //Define app logic that is fired when the event occurs - simply track the time 
    //when the event occurred. 
    public void onEvent(EventIterator itr) {
        Calendar cal = Calendar.getInstance();
        //log the time when the event occurred 
        log.info("A new node was added to content/claim at : " +cal.getTime());         
    }
}

另见：

可以通过ObservationManager对象注册EventListener。异步通知事件侦听器，并在事件发生和事务提交后查看事件。事件侦听器仅查看注册它的会话具有足够访问权限的事件
