数据绑定（java类与ActionScript类绑定）

本文主要是介绍数据绑定（java类与ActionScript类绑定），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Book.as文件

package
{
   //这里[Bindable]是可绑定的，[RemoteClass(alias="Book")]是和Java代码中的Book类关联起来。这样就可以利用类型转换来将Java对象转换为AS对象了。
   [Bindable]
   [RemoteClass (alias="book.Book")]
   public class Book
   {
       public function Book()
       {
       }
       public var isbn:String;
       public var title:String;
       public var price:int;
   }
}

Book类

package book;

public class Book {
   private String isbn;
   private String title;
   private double price;

//get，set方法。。。

}

BookDao类

package book;

import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
import java.util.concurrent.ConcurrentHashMap;
import java.util.concurrent.ConcurrentMap;
import book.Book;

public class BookDao {
