本文整理了Java中org.apache.catalina.Context.getServletContext()方法的一些代码示例，展示了Context.getServletContext()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。Context.getServletContext()方法的具体详情如下：
包路径：org.apache.catalina.Context
类名称：Context
方法名：getServletContext

Context.getServletContext介绍

[英]Return the servlet context for which this Context is a facade.
[中]返回此上下文为其外观的servlet上下文。
