Flex 应用Remote与后台通信

 

1.创建模拟Services：（DataRomate.java类中getList()方法遍历数据）

public class DataRomate
{
    public List getList()
    {
        List list = new ArrayList();
        for(int i=0;i<10; i++)
        {
            Map map = new HashMap();
            map.put("name", "name"+i);
            map.put("description", "description"+i);
            map.put("targeingexpression", "targeingexpression"+i);
            map.put("userdby", "userdby"+i);
            map.put("porfilechart", "porfilechart"+i);
            list.add(map);
        }
        return list;

public class DataRomate 
{
	public List getList()
	{
		List list = new ArrayList();
		for(int i=0;i<10; i++)
		{
			Map map = new HashMap();
			map.put("name", "name"+i);
			map.put("description", "description"+i);
			map.put("targeingexpression", "targeingexpression"+i);
			map.put("userdby", "userdby"+i);
			map.put("porfilechart", "porfilechart"+i);
			list.add(map);
		}
		return list;

2.配置：remoting-config.xml

<destination id="DataRo">
    <properties>
        <source>com.test.DataRomate</source>
    </properties>
</destination>

   <destination id="DataRo">
       <properties>
           <source>com.test.DataRomate</source>
       </properties>
   </destination>

3.*.mxml获取数据：
   A : getData(event:ResultEvent)方法实现数据绑定

  public function getData(event:ResultEvent):void
  {
dataGridId.dataProvider = event.result;
  }

    public function getData(event:ResultEvent):void
    {
	 dataGridId.dataProvider = event.result;
    }

   B: 组件设置：
  

<mx:RemoteObject id="DataRo" destination="DataRo" result="getData(event)" />

    <mx:RemoteObject id="DataRo" destination="DataRo" result="getData(event)" />
   

   C:设置DataGrid组件：
  

<mx:DataGrid id="dataGridId" creationComplete="DataRo.getList()">
    <mx:columns>
    <mx:DataGridColumn dataField="name" headerText="Name"/>
    <mx:DataGridColumn dataField="description" headerText="Description"/>
           pression"/>
    <mx:DataGridColumn dataField="userdby" headerText="Used by"/>
    <mx:DataGridColumn dataField="porfilechart" headerText="Porfile Chart"/>
    </mx:column

    
<mx:DataGrid id="dataGridId" creationComplete="DataRo.getList()">
    <mx:columns>
	<mx:DataGridColumn dataField="name" headerText="Name"/>
	<mx:DataGridColumn dataField="description" headerText="Description"/>
           pression"/>
	<mx:DataGridColumn dataField="userdby" headerText="Used by"/>
	<mx:DataGridColumn dataField="porfilechart" headerText="Porfile Chart"/>
    </mx:column
   

   注意：creationComplete="DataRo.getList()" ： getList()对应DataRomate.java类中getList()方法。
