jdbc配置文件不读是为什么

我写的jdbc配置文件名字叫jdbc.properties
报错总是说在其他配置文件中找内容。。

配置文件jdbc.properties中:
jdbc.driver=com.MySQL.jdbc.Driver;
jdbc.url=jdbc:mysql://localhost:3306/xxx;
jdbc.user=sa;
jdbc.pw=sa;

代码中:
//获取文件配置信息
Properties pro = new Properties();
pro.load(Conn.class.getResourceAsStream("jdbc.properties"));

String url = pro.getProperty("jdbc.url");
String user = pro.getProperty("jdbc.user");
String pwd = pro.getProperty("jdbc.pw");
String driver = pro.getProperty("jdbc.driver");

//连接
Class.forName(driver);
conn = DriverManager.getConnection(url, user, pwd);

仔细看下有没有引入架包
