as对象与java对象的转换

java对象不能直接转换为flex对象，所以需要创建一个as对象对应java对象，并且以[RemoteClass(alias="hello.User")] 
来指定对应的java对象类。下面我就以一个简单的例子来诠释交互

此例子在上一个例子中稍作改动即可应用

java类

package hello;

public class User {

    private long id;
    private String name;
    private String password;
    private long age;
    public long getId() {
        return id;
    }
    public void setId(long id) {
        this.id = id;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public long getAge() {
        return age;
    }
    public void setAge(long age) {
        this.age = age;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

}

package hello;

public class User {

	private long id;
	private String name;
	private String password;
	private long age;
	public long getId() {
		return id; 
	}
	public void setId(long id) {
		this.id = id;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public long getAge() {
		return age;
	}
	public void setAge(long age) {
		this.age = age;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	
}

 

 as

 

package
{
[RemoteClass(alias="hello.User")]
    public class User
    {
     public  var name:String;
     public  var password:String;
     public var age:int;
     public var id:int;
        public function User()
        {
        }
    }
}

package
{
[RemoteClass(alias="hello.User")]  
	public class User 
	{
     public  var name:String;
     public  var password:String;
     public var age:int;
     public var id:int;
		public function User()
		{
		}
	} 
}
