webservice 数据绑定与映射

来源：互联网发布：java向移动推送原理图编辑：程序博客网时间：2024/05/16 13:40

webservice 中将java转换为 XML Schema(有别于基本类型的复杂类型定义)的过程称序列化，反之为反序列化。数据绑定和Java/XML是实现这个过程的的两种机制

一.JAXB数据绑定

1.如下XML Schema 可以通过模式编译器生成 java 类

1) 命名空间 http://www.example.com/oms 对于java 类中的包 com.example.oms

2) 元素 billTo 对于java 类中 billTo 属性。

3） items 对应一个 Items 类对象 Items 类中有一个 List属性item 这个 list中装的都是 ItemType对象

2. 定义JAXB 值类。通过模式生成器将其转换为 XML 模式
