问题描述

我需要读取一个配置文件运行以下代码时出现此错误:

I need to read a config file I get this error while running the following code:

文件 config.cfg 存在并且具有 r/w 权限.

The file config.cfg is present and has r/w permissions.

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

public class Config   
{
 Properties configFile;
 public Config()
 {
configFile = new java.util.Properties();
try {           
  configFile.load(this.getClass().getClassLoader().
  getResourceAsStream("config.cfg"));           
}catch(Exception eta){
     eta.printStackTrace();
}
}

public String getProperty(String key)
{

 String value = this.configFile.getProperty(key);       
 return value;

 }

}
