java.io.FileNotFoundException：.\cfg\users (系统找不到指定的路径)
提问于 2018-09-23 20:41:46
我已经创建了一个动态Web项目(用来生成和发送报告)
Eclipse中的项目层次结构
Project
src(folder)
-metier(Package)
-Util.java(Class)
-web
-ControlleurServlet.java (Servlet)
cfg(folder)
-USERS(file)
WebContent
- gui.jsp (Html form)当我将Util class (方法: sendMail)作为一个Java项目运行时，它是工作的：
Util类：
public class Util {
static String cvsSplitBy = ";";
public static String MAILCONFIGURATION="./cfg/mailConfiguration";
public static String USERS="./cfg/users";
public static String SHIFTS="./cfg/shifts";
.
.
.sendMail方法从文件中检索一些数据。
但是当我在服务器上运行项目并从Servlet调用sendMail时，我得到了这个错误：

servlet上下文没有指向您保存文件的相同路径，
因此，您可以检查上下文路径，并将文件夹放在适当的位置。
它应该能解决你的问题
