查看数据库驱动程序是否安装

public class LookForDriver {

/**

*/
public static void main(String[] args) {
// TODO Auto-generated method stub
try {
String className = "com.mysql.jdbc.Driver";
Class driverObject = Class.forName(className);
//上面这句本身就带有判断性质，找不到，直接catch
System.out.println("driverObject=" + driverObject);
System.out.println("your installation of JDBC Driver OK.");
} catch (Exception e) {
System.out.println("Failed: JDBC Driver Error: " + e.getMessage());
}
