java 属性文件读取工具类

 

哎 .  年纪大了就越来越懒了...  不废话,直接代码了.

 

 

public class PropertiesTools {
	
	/**
	 *读取资源文件(在容器中)
	 * @param fileName  这个是从根目录开始 eg:conf/area.properties
	 * @return
	 */
	public static  String getProperties(String key,String fileName){
		Properties rc = null;
		try {
			rc = new Properties();
			ClassLoader cl = new PropertiesTools().getClass().getClassLoader();
			InputStream is = cl.getResourceAsStream(fileName);
			rc.load(is);
			
		} catch (IOException e) {
			e.printStackTrace();
		}
		return rc.getProperty(key);
	}
}
