DriverManager没有合适的驱动程序mysql

首先，您需要在连接之前加载JDBC驱动程序

// Notice, do not import com.mysql.jdbc.*// or you will have problems!//Load Drivertry {  // The newInstance() call is a work around for some  // broken Java implementations  Class.forName("com.mysql.jdbc.Driver").newInstance();} catch (Exception ex) {  // handle the error}con=DriverManager.getConnection(connectieString);System.out.println ("Database connection established");

运行应用程序时，请确保在类路径上具有mysql-connector-java-5.xx-bin.jar。
