java 加载MYSQL驱动 找不到类

参考下：
public class DBConnection {
private static final String DBDRIVER = "com.mysql.jdbc.Driver"; // 驱动类类名
private static final String DBURL = "jdbc:mysql://127.0.0.1:3306/test";// 连接URL
private static final String DBUSER = "root"; // 数据库用户名
private static final String DBPASSWORD = "123"; // 数据库密码
public static Connection getConnection() {
Connection conn = null;
try {
Class.forName(DBDRIVER).newInstance(); // 注册驱动
conn = DriverManager.getConnection(DBURL, DBUSER, DBPASSWORD); // 获得连接对象
} catch (Exception e) {
e.printStackTrace();
}
return conn;
}
