两种读取数据库配置文件的方式
1、ResourceBundle
ResourceBundle bundle = ResourceBundle.getBundle("jdbc"); //读取配置文件 配置文件在类的同一目录下,不同时需要加入路径 jdbc.properties
url = bundle.getString("url");
user = bundle.getString("user");
password = bundle.getString("password");
driverclass = bundle.getString("driverclass");
2、Properties
Properties properties = new Properties();
try {
properties.load(this.getClass().getResourceAsStream("/jdbc.properties"));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String driver = properties.getProperty("driver");
String user = properties.getProperty("user");
String password = properties.getProperty("password");
String url = properties.getProperty("url");
