JAVA 讀取配置檔案的實現類

1. 配置檔案 myconf.properties

url=www.baidu.com

2. 類檔案 MyProperties.class

public class MyConf {
	public static Properties properties = new Properties();

	public static String url= getPropertieVal("url");

	public static String getPropertieVal(String propertype){
		if(properties==null || properties.size()==0) readProperties();
		return properties.getProperty(propertype);
	}

	public static void readProperties() {
		try {
			properties.load(MyConf.class.getResourceAsStream("/myconf.properties"));
		}catch(FileNotFoundException e){
			System.out.println("Error read");
		}
		catch (IOException e) {
			e.printStackTrace();
		}
	}
}

3. 呼叫

Class Test {

    public static void main(String[] args) {
        System.out.println(MyConf.url);
	}

}
