如jar所示，执行“系统找不到指定的属性文件". [英] Executing as jar says "System cannot find the properties file specified"

问题描述

我在 src/main/resources 文件夹中有一个带有 app.properties 文件的gradle项目.

I have a gradle project with app.properties file present in the src/main/resources folder.

当我尝试使用jar执行项目时，它说无法读取指定的app.properties文件.

When i am trying to execute the project using jar, it says not able to read the app.properties file specified.

下面是读取属性文件的代码:

Below is the code to read the properties file :

  Properties properties = new Properties();  
  File file = new File("src/main/resources/app.properties");
  FileInputStream inputStream = new FileInputStream(file);
  properties.load(inputStream);

我正在使用以下命令来运行jar:

I am using below command to run the jar :

Java -jar App.jar

在此问题上的任何帮助将不胜感激.

Any help on this issue will be appreciated.

推荐答案

尝试使用getSystemResourceAsStream

 try (InputStream inputStream = ClassLoader.getSystemResourceAsStream("app.properties"))
