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

ServletContext.getContext介绍

[英]Returns a ServletContext object that corresponds to a specified URL on the server.

This method allows servlets to gain access to the context for various parts of the server, and as needed obtain RequestDispatcherobjects from the context. The given path must be begin with "/", is interpreted relative to the server's document root and is matched against the context roots of other web applications hosted on this container.

In a security conscious environment, the servlet container may return null for a given URL.
[中]返回与服务器上指定URL相对应的ServletContext对象。
此方法允许servlet访问服务器各个部分的上下文，并根据需要从上下文中获取RequestDispatcherObject。给定路径必须以“/”开头，相对于服务器的文档根进行解释，并与托管在此容器上的其他web应用程序的上下文根进行匹配。
在有安全意识的环境中，servlet容器可能会为给定的URL返回null。
