java - java.io.FileNotFoundException: .\cfg\users（系统找不到指定的路径）

问题描述

我创建了一个动态 Web 项目（用于生成和发送报告）

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 类（方法：sendMail）作为 Java 项目运行时，它正在工作：

实用类：

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，我收到了这个错误：

解决方案

servlet 上下文未指向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保存在适当的位置。

它应该可以解决您的问题
