如何使用NetBeans中的相对路径加载文件

Question

import java.io.*;
import java.util.Properties;

public class NewClass {
    public static void main(String args[]) throws IOException  {
        Properties p = new Properties();
        p.load(new FileInputStream("DBDriverInfo.properties"));
        String url=p.getProperty("url");
        String user=p.getProperty("username");
        String pass=p.getProperty("password");
        System.out.println(url+"\n"+user+"\n"+pass);
    }
}

虽然文件DBDriverInfo.properties文件位于同一目录中,但会引发以下异常.

Exception in thread "main" java.io.FileNotFoundException: DBDriverInfo.properties (The system cannot find the file specified)
    at java.io.FileInputStream.open(Native Method)
    at java.io.FileInputStream.<init>(FileInputStream.java:138)
    at java.io.FileInputStream.<init>(FileInputStream.java:97)
    at NewClass.main(NewClass.java:7)

javac在命令行界面中编译时,相对路径工作正常.但NetBeans中的异常引发了异常.

在Netbeans中,您需要将该文件放在项目文件夹中而不是src/package文件夹中.
