从Servlet访问Tomcat上下文路径 [英] Accessing Tomcat Context Path from Servlet

问题描述

在我的Servlet中，我想访问上下文的根，以便可以进行一些JavaScript精简.

In my Servlet I would like to access the root of the context so that I can do some JavaScript minifying.

可以在安装过程中进行最小化，但我想在Servlet启动时进行以减小实现成本.

It would be possible to do the minify as part of the install process but I would like to do it on Servlet startup to reduce the implementation cost.

有人知道获取上下文目录的方法，以便我可以将文件加载和写入磁盘吗?

Does anyone know of a method for getting the context directory so that I can load and write files to disk?

推荐答案

这应该为您提供可用于提取/编辑文件的真实路径.

This should give you the real path that you can use to extract / edit files.

我们正在上下文侦听器中做类似的事情.

We're doing something similar in a context listener.

public class MyServlet extends HttpServlet {

    public void init(final ServletConfig config) {
        final String context = config.getServletContext().getRealPath("/");
        ...
    }

    ...
}
