Flex中ArrayCollection 与java中的ArrayList互转

               FlexArrayCollection java中的ArrayList互转

 

这里说这是Flexremoting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;

    }

 

FlexVO

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];

                     }

              }

 

       }

}

 

JavaModuleVO

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;

       }

}

 

JavaconvertArrayCollection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);

        }  

   }

 

       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(java端传到Flex端也是一样),只不过ArrayCollectionvo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Flexvo对象中的属性要用public.

 

 

Flex端传给Java端一个ArrayCollectionJava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(“FlexVO的字段名”).toString() ;

}
