实现JavaBean与ActionScript的VO之间的转换.

 

 

    ActionScript与Java一样是面向对象的开发程序.二者之间的相同之处很多.

 

    有的时候,我们在编写JavaBean后,需要创建对应的AS对象.在数量很少的情况下,也许并不觉得繁琐.但是当你的JavaBean存在几十个,数百个的时候,是否希望有一种方式能够自动生成AS的vo?

 

    这里将为你展示,我所编写的时间Java与ActionScript之间自动生成的代码.由于程序刚写完,并未完善,故比较粗糙,请勿见笑.如果哪位朋友有更好的转换方法,请邮箱(eclipser@163.com)发送给我,鄙人在此十分感谢!

编写测试的JavaBean

** * 玩家表 * * @author Vicky */ @Entity @Table(name = "lesogo_user") public class User implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.AUTO) private Integer id; @Column(length = 20, unique = true, nullable = false) private String user_name; @Column(length = 32, nullable = false) private String user_password; @Column(length = 2, nullable = false) private Integer user_rank = 1; @Column(length = 5, nullable = false) private Integer user_experience = 0; @Column(length = 10, nullable = false) private Integer user_money = 0; @Column(length = 5, nullable = false) private Integer user_charm = 0; @Column(length = 3, nullable = false) private Integer user_skills = 1; @Column(length = 20, nullable = false) private String user_trbal; @ManyToOne(cascade = { CascadeType.REFRESH }, optional = true, fetch = FetchType.LAZY) @JoinColumn(name = "user_village_id") private Villages user_village_id; @Temporal(TemporalType.TIMESTAMP) @Column(nullable = false) private Date user_create_time = new Date(); @Column(length = 19) private String user_login_time; @Column(length = 1, nullable = false) private Integer user_isLogin = 0; @OneToMany(cascade = { CascadeType.ALL }, fetch = FetchType.LAZY, mappedBy = "friendships_owner") private Set<Friendships> userID = new HashSet<Friendships>(); @OneToMany(cascade = { CascadeType.REFRESH }, fetch = FetchType.LAZY, mappedBy = "friendships_friend") private Set<Friendships> friendID = new HashSet<Friendships>(); @OneToOne(cascade = { CascadeType.ALL }, fetch = FetchType.LAZY) @JoinColumn(name = "user_forbidden_id") private Forbidden user_forbidden_id; // getter & setter

生成ActionScript

package cn.vicky.pojo{ public class User{ public function User(){} public var id:Number; public var user_name:String; public var user_password:String; public var user_rank:Number; public var user_experience:Number; public var user_money:Number; public var user_charm:Number; public var user_skills:Number; public var user_trbal:String; public var user_village_id:Villages; public var user_create_time:Date; public var user_login_time:String; ... }
