开发笔记:获取路径

request.getSession().getServletContext().getRealPath("/");

this.getClass().getClassLoader().getResource("").getPath();

public static String getRealWebappsPath(HttpServletRequest request) {
String webPath = request.getSession().getServletContext().getRealPath(
"/");
String basePath = webPath.substring(0, webPath.indexOf(request
.getContextPath().substring(1)));
return basePath;
}
