本文介绍了一个基于状态切换实现的报警数据展示系统。系统通过触发alarm事件，利用Flex的DataGrid组件显示从数据库中获取的报警信息，并每60分钟自动刷新数据。

当状态切换时，触发alarm事件，在事件里调用数据库的操作函数，取得数据绑定在新状态下的datagrid组件上

新的stste

<mx:State name="alarm" activate="alarm()" >
            <mx:RemoveChild target="{image1}"/>
            <mx:AddChild relativeTo="{canvas1}" position="lastChild">
                <mx:DataGrid x="0" y="0" width="100%" height="100%" id="db1" dataProvider="{myarray}" >
                <mx:columns>
                  <mx:DataGridColumn headerText="id" dataField="alarmId"/>
                  <mx:DataGridColumn headerText="报警设备" dataField="deviceId"/>
                  <mx:DataGridColumn headerText="报警时间" dataField="alarmDate"/>
                  <mx:DataGridColumn headerText="报警信息" dataField="alarmNote"/>
                  <mx:DataGridColumn headerText="报警进程" dataField="alarmProcess"/>
                  <mx:DataGridColumn headerText="报警次数" dataField="alarmTimes"/>
                </mx:columns>
              </mx:DataGrid>
            </mx:AddChild>
        </mx:State>

script里的函数

public function alarm() :void {
           remoteControl.getData();
           remoteControl.addEventListener(ResultEvent.RESULT,onResult);
             setintervalID=setInterval(alarm,600000);//刷新60分钟
       }

       public function onResult(event:ResultEvent) :void{
              myarray=ArrayCollection(event.result);
              //db1.dataProvider = myarray;
   }

组件

<mx:RemoteObject destination="Control" id="remoteControl"/>

<mx:Button label="网络故障管理" fontFamily="Verdana" fontSize="15" color="#105FE1" icon="@Embed(source='../img/wlgz.png')" textRollOverColor="#3171F4" textSelectedColor="#3171F4" click="currentState='alarm'" />

java程序

alarmbean：

package data;

public class AlarmBean {
    private int alarmId;
    private String deviceId;
    private String alarmData;
    private int alarmType;
    private String alarmNote;
    private int alarmState;
    private int alarmTimes;
    private String alarmProcess;


    //alarmId
    public void setalarmId(int alarmId){
        this.alarmId = alarmId;
    }
    public int getalarmId(){
        return alarmId;
    }
    //deviceId
    public void setdeviceId(String deviceId){
        this.deviceId = deviceId;
    }
    public String getdeviceId(){
        return deviceId;
    }
    //alarmData
    public void setalarmData(String alarmData){
        this.alarmData = alarmData;
    }
    public String getalarmData(){
        return alarmData;
    }
    //alarmType
    public void setalarmType(int alarmType){
        this.alarmType = alarmType;
    }
    public int getalarmType(){
        return alarmType;
    }
    //alarmNote
    public void setalarmNote(String alarmNote){
        this.alarmNote = alarmNote;
    }
    public String getalarmNote(){
        return alarmNote;
    }
    //alarmState
    public void setalarmState(int alarmState){
        this.alarmState = alarmState;
    }
    public int getalarmState(){
        return alarmState;
    }
    //alarmTimes
    public void setalarmTimes(int alarmTimes){
        this.alarmTimes = alarmTimes;
    }
    public int getalarmTimes(){
        return alarmTimes;
    }
    //alarmProcess
    public void setalarmProcess(String alarmProcess){
        this.alarmProcess= alarmProcess;
    }
    public String getalarmProcess(){
        return alarmProcess;
    }

}

控制函数

package data;

import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;
import data.TestDao;
import data.AlarmBean;
import data.DeviceBean;

public class Control {
    TestDao test=new TestDao();
    public List getData(){
        System.out.println("list");
        ArrayList list=new ArrayList();
        String sql="select * from t_alarm";
        ResultSet rs=test.selectSql(sql);
        System.out.println(rs.toString());
        try {
            while(rs.next()){
           AlarmBean db=new AlarmBean();
        db.setalarmId(rs.getInt("alarmId"));
        db.setdeviceId(rs.getString("deviceId"));
        db.setalarmData(rs.getString("alarmDate"));
        db.setalarmNote(rs.getString("alarmNote"));
        db.setalarmProcess(rs.getString("alarmProcess"));
        db.setalarmTimes(rs.getInt("alarmTimes"));
        if(db.getalarmState()==0&&db.getalarmTimes()>=2)
        list.add(db);
        System.out.println("hello");
            }
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    System.out.println(list.toString());
     return list;

    }}
