java读取properties文件开发

 

java读取properties配置文件的一种方法

      配置.properties文件和java类在同一级目录下

　　java代码的具体实现如下：

public class GuiDangProperties {

    private static GuiDangProperties instance = new GuiDangProperties();
    
    public GuiDangProperties getInstance(){
        return instance;
    }
    
    public static Properties getProperties(){
        GuiDangProperties properties = new GuiDangProperties();
        InputStream in = properties.getClass().getResourceAsStream("guidang.properties");
        Properties pro = new Properties();
        try {
            pro.load(in);
            return pro;
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }

    public static String getParamter(String name) {
        return  instance.getProperties().getProperty(name);
    }

}
