本文整理了Java中org.springframework.web.context.support.WebApplicationObjectSupport类的一些代码示例，展示了WebApplicationObjectSupport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。WebApplicationObjectSupport类的具体详情如下：
包路径：org.springframework.web.context.support.WebApplicationObjectSupport
类名称：WebApplicationObjectSupport

WebApplicationObjectSupport介绍

[英]Convenient superclass for application objects running in a WebApplicationContext. Provides getWebApplicationContext(), getServletContext(), and getTempDir() accessors.

Note: It is generally recommended to use individual callback interfaces for the actual callbacks needed. This broad base class is primarily intended for use within the framework, in case of ServletContext access etc typically being needed.
[中]为在WebApplicationContext中运行的应用程序对象提供方便的超类。提供getWebApplicationContext（）、getServletContext（）和getTempDir（）访问器。
注意：对于实际需要的回调，通常建议使用单独的回调接口。这个广泛的基类主要用于框架内，以防通常需要ServletContext访问等。
