本文整理了Java中org.springframework.oxm.Marshaller类的一些代码示例，展示了Marshaller类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Marshaller类的具体详情如下：
包路径：org.springframework.oxm.Marshaller
类名称：Marshaller

Marshaller介绍

[英]Defines the contract for Object XML Mapping Marshallers. Implementations of this interface can serialize a given Object to an XML Stream.

Although the marshal method accepts a java.lang.Object as its first parameter, most Marshaller implementations cannot handle arbitrary Objects. Instead, a object class must be registered with the marshaller, or have a common base class.
[中]定义对象XML映射封送器的约定。该接口的实现可以将给定对象序列化为XML流。
尽管封送处理方法接受java。对象作为其第一个参数，大多数Marshaller实现无法处理任意对象。相反，对象类必须在封送处理程序中注册，或者具有公共基类。
