本文整理了Java中javax.activation.DataHandler.getDataContentHandler()方法的一些代码示例，展示了DataHandler.getDataContentHandler()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。DataHandler.getDataContentHandler()方法的具体详情如下：
包路径：javax.activation.DataHandler
类名称：DataHandler
方法名：getDataContentHandler

DataHandler.getDataContentHandler介绍

[英]Get the DataContentHandler for this DataHandler:

If a DataContentHandlerFactory is set, use it. Otherwise look for an object to serve DCH in the following order:

1. if a factory is set, use it

2. if a CommandMap is set, use it

3. use the default CommandMap

In any case, wrap the real DataContentHandler with one of our own to handle any missing cases, fill in defaults, and to ensure that we always have a non-null DataContentHandler.
[中]获取此DataHandler的DataContentHandler：
如果设置了DataContentHandlerFactory，请使用它。否则，按以下顺序查找要为DCH服务的对象：
1） 如果设置了工厂，请使用它
2） 如果设置了CommandMap，请使用它
3） 使用默认的CommandMap
在任何情况下，使用我们自己的DataContentHandler包装真实的DataContentHandler，以处理任何缺失的情况，填写默认值，并确保始终具有非空DataContentHandler。
