eclipse连接不到mysql数据库

我的MySQL版本是5.7.17
jar包是mysql-connector-java-5.1.44-bin

public static Connection getConnection() {
try {
Class.forName(OracleDriver.class.getName());
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
System.out.println("驱动未找见");
}
String url = "jdbc:oracle:thin:@localhost:1521:eduask";
String user = "system";
String password = "root";
Connection conn=null;
try {
conn = DriverManager.getConnection(url, user, password);
} catch (SQLException e) {
// TODO Auto-generated catch block
System.out.println(e.getMessage());
}

    return conn;

}

把127.0.0.1换成localhost

jdbc:mysql://127.0.1:3306/test这块不用分开写，非要分开写的话应该是这样写 "jdbc:mysql:"+"///127.0.1:3306/test";
