Flex中ArrayCollection 与java中的ArrayList互转

?????????????? Flex中ArrayCollection 与java中的ArrayList互转

?

这里说这是Flex用remoting传一个ArrayCollection到后台(后台也用ArrayCollection接参)之后如何转成ArrayList.

（具体操作如将Flex页面的DataGrid中的若干内容添加到DataBase中）

?

public ArrayList convertArrayCollection(ArrayCollection array){

??????? ArrayList myObjectArray = new ArrayList();

??????? ASTranslator ast = new ASTranslator();

??????? ModuleVO myObject;

??????? ASObject aso;

?

??????? for (int i=0;i < array.size(); i++){

??????? ????myObject = new ModuleVO ();

??????????? aso = new ASObject();

?

??????????? aso = (ASObject) array.get(i);

??????????? aso.setType("com.hospital.vo.ModuleVO");

??????????? myObject = (ModuleVO) ast.convert(aso,ModuleVO.class);

??????????? myObjectArray.add(myObject);

??????? }

??????? return myObjectArray;

??? }

?

Flex端VO：

package vo

{

?????? [Bindable]

?????? public class ModuleVO

?????? {

????????????? public var num:Number;

?????????????

????????????? public var MID:int;

????????????? public var MCode:String;

????????????? public var MCN:String;

????????????? public var MEN:String;

????????????? public var MState:int;

?????????????

????????????? public function fill(obj:Object):void{

???????????????????? for(var i:* in obj){

??????????????????????????? this[i]=obj[i];

???????????????????? }

????????????? }

?

?????? }

}

?

Java端ModuleVO：

package com.hospital.vo;

?

public class ModuleVO {

?????? public Number num;

?

?????? public int MID;

?????? public String MCode;

?????? public String MCN;

?????? public String MEN;

?????? public int MState;

?????? public Number getNum() {

????????????? return num;

?????? }

?????? public void setNum(Number num) {

????????????? this.num = num;

?????? }

?????? public int getMID() {

????????????? return MID;

?????? }

?????? public void setMID(int mid) {

????????????? MID = mid;

?????? }

?????? public String getMCode() {

????????????? return MCode;

?????? }

?????? public void setMCode(String code) {

????????????? MCode = code;

?????? }

?????? public String getMCN() {

????????????? return MCN;

?????? }

?????? public void setMCN(String mcn) {

????????????? MCN = mcn;

?????? }

?????? public String getMEN() {

????????????? return MEN;

?????? }

?????? public void setMEN(String men) {

????????????? MEN = men;

?????? }

?????? public int getMState() {

????????????? return MState;

?????? }

?????? public void setMState(int state) {

????????????? MState = state;

?????? }

}

?

Java取convertArrayCollection里面的数据：

?????? public boolean addMV( ArrayCollection ModuleList) {

????????????????????

????????????? ArrayList al = this.convertArrayCollection(ModuleList) ;

for(Iterator i = al.iterator(); i.hasNext();)??? {??

??????????? String MID = ((ModuleVO)i.next()).getMID()+"";?

??????????? System.out.println(MID);

???????????

???????????????????? String sql = "insert into T_ModuleV (MVID,MID,MState) values " +

?????????????????????????????????? "("+MVID+","+MID+","+MState+") ; ";

???????????????????? System.out.println(sql);

??????? }??

?? }

?

?????? 将Flex端传过来的ArrayConllection转为Java端的ArrayList

?????? public ArrayList convertArrayCollection(ArrayCollection array){

??????? ArrayList myObjectArray = new ArrayList();

??????? ASTranslator ast = new ASTranslator();

??????? ModuleVO myObject;

??????? ASObject aso;

?

??????? for (int i=0;i < array.size(); i++){

??????????? myObject = new ModuleVO();

??????????? aso = new ASObject();

?

??????????? aso = (ASObject) array.get(i);

??????????? aso.setType("com.hospital.vo.ModuleVO");

??????????? myObject = (ModuleVO) ast.convert(aso,ModuleVO.class);

??????????? myObjectArray.add(myObject);

??????? }

??????? return myObjectArray;

??? }

?

其实传一个对象集合到后台的话直接在后台用ArrayList接参就可以(从java端传到Flex端也是一样),只不过ArrayCollection的vo对象要和后台中的bean对应起来(属性名一样,否则接不到值),需要注意的是Flex中vo对象中的属性要用public.

?

?

Flex端传给Java端一个ArrayCollection，Java端用ArrayList接收，之后循环遍历ArrayList，强转，就会取到Flex端传过来的值

?

For(int I = 0; i<arrayList.size();i++ ){

?????? HashMap map = (HashMap)arrayList.get(i) ;

?????? String A = map.get(“Flex端VO的字段名”).toString() ;

}
