Lesson: Introduction to JAXB课程：JAXB简介

Java Architecture for XML Binding (JAXB) provides a fast and convenient way to bind XML schemas and Java representations, making it easy for Java developers to incorporate XML data and processing functions in Java applications. Java Architecture for XML Binding(JAXB)为绑定XML模式和Java表示提供了一种快速方便的方法，使Java开发人员能够轻松地将XML数据和处理功能集成到Java应用程序中。As part of this process, JAXB provides methods for unmarshalling (reading) XML instance documents into Java content trees, and then marshalling (writing) Java content trees back into XML instance documents. JAXB also provides a way to generate XML schema from Java objects.作为这个过程的一部分，JAXB提供了将XML实例文档解组（读取）为Java内容树的方法，然后将Java内容树编组（写入）为XML实例文档。JAXB还提供了一种从Java对象生成XML模式的方法。

JAXB 2.0 includes several important improvements to JAXB 1.0:JAXB 2.0包括对JAXB 1.0的几个重要改进：

• Support for all W3C XML Schema features. 支持所有W3C XML模式功能。(JAXB 1.0 did not specify bindings for some of the W3C XML Schema features.)（JAXB 1.0没有为一些W3C XML模式特性指定绑定。）
• Support for binding Java-to-XML, with the addition of the javax.xml.bind.annotation package to control this binding. 支持将Java绑定到XML，并添加javax.xml.bind.annotation包来控制此绑定。(JAXB 1.0 specified the mapping of XML Schema-to-Java, but not Java-to-XML Schema.)（JAXB 1.0指定了XML模式到Java的映射，但没有指定Java到XML模式的映射。）
• A significant reduction in the number of generated schema-derived classes.生成的模式派生类的数量显著减少。
• Additional validation capabilities through the JAXP 1.3 validation APIs.通过JAXP 1.3验证API提供额外的验证功能。
• Smaller runtime libraries.更小的运行库。

This lesson describes the JAXB architecture, functions, and core concepts, and provides examples with step-by-step procedures for using JAXB.本课程介绍了JAXB体系结构、功能和核心概念，并提供了使用JAXB的分步过程示例。
