放置属性文件的位置（与Maven程序集有关）

Question

When I start my application within eclipse, it's no problem to have a properties file within the src/main/resources folder. When I then run maven install , this properties file is put into a config folder with the help of maven assembly. So following issue:

While working in eclipse, I access the properties file simply with:

File propsFile = new File( "src/main/resources/settings.properties" );

After maven install I cannot reach this file anymore of course. But which workflow is the best, to reach the file during my eclipse development and after maven install without having it twice?!

My assembly structure after maven install looks like this:

application folder
    |----bin
        |----batch file to start my application
    |----lib
        |----my application jar
        |----other dependencies jars
    |----config
        |----settings.properties

Thanks a lot in advance already :)

If you are launching your app through a script file, I'd suggest you to include into the classpath the folder where settings.properties is located at:

• In Eclipse you have to do nothing at all, because all the files from src\\main\\resources are actually copied right into the target\\classes output directory, which is indeed at the heading of the classpath.

• And in your script file, you have only to pre-pend the <application>\\config file at the beginning of the execution classpath.

But then you have to change the way you read resources from program: Replace using the File API by ClassLoader.getResourceAsStream :

InputStream input=getClass().getClassLoader().getResourceAsStream("settings.properties");
Properties properties=new Properties(input);
