推荐答案

它将返回您在 webapps 目录中的项目的路径.

It returns you path to your project in webapps directory.

例如，如果您的项目名称为myProj，它将返回/myProj

For instance, if your project name is myProj,that it will return /myProj

如我所见，需要避免对您的Web项目名称进行硬编码.例如，您的.war文件(包含您的项目的存档文件)可能以不同的方式命名，并且您不应该知道将在webapps中提取的确切名称.

As I see,it's needed to avoid hardcoding of your web-project name. For instance, you .war file(archive,that contains your project) may be named different ways and you shouldn't know what exactly name it will be extracted under webapps.
