Java数据库查询未连接

由于某些原因，我的应用程序将无法连接，我不确定是哪里出了问题，以下是我收到的错误，显示了有关驱动程序连接错误的信息。我试图使用

Class.forName（）

方法连接的是

JDBC-ODBC桥驱动程序

Exception in thread "main" java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

从：

。。。JDBC-ODBC桥将在JDK 8中删除。此外，甲骨文
不支持JDBC-ODBC网桥。Oracle建议您使用
数据库供应商提供的JDBC驱动程序，而不是
JDBC-ODBC桥

您使用的是Java 8吗？我记得JdbcOdbc驱动程序存在一些不兼容的地方，您应该尝试在Google中查找它们ODBC连接是否已定义？
package databasequery;
