搞不懂state节点有什么事情？

大概明白了

state节点上可以注册<event>,通过event实现与外部系统的交互。示例如下：

<state name="等待状态节点">
<event type="node-enter">
<script>
System.out.println(&quot;test  process &quot;);
</script>
<action name="test" class="test.action.HelloWorldAction"></action>
</event>
<event type="node-leave">
<script name="leave test">
System.out.println(&quot;离开等待状态&quot;);
</script>
</event>
<transition to="state1" name="to state1"></transition>
<transition name="a" to="结束节点"></transition>
</state>
