三種將公用配置文件讀取爲InputStream的方法

類名：IConstants.java 

private static final String FILEPATH="config.properties";  
  
BufferedReader br = new BufferedReader(new InputStreamReader(SequenceReader.class.getClassLoader().getResourceAsStream(FILEPATH)));  
  
BufferedReader br = new BufferedReader(new InputStreamReader(this.getClass().getClassLoader().getResourceAsStream(FILEPATH)));  
  
BufferedReader br = new BufferedReader(new InputStreamReader(Thread.currentThread().getContextClassLoader().getResourceAsStream(FILEPATH)));  
  
InputStream is  = this.getClass().getClassLoader().getResourceAsStream(FILEPATH);
