1、加载JDBC驱动程序：在连接数据库之前，首先要加载想要连接的数据库的驱动到JVM（Java虚拟机），这通过java.lang.Class类的静态方法forName(String className)实现。 例如： try{ //加载MySql的驱动类 Class.forName("com.mysql.jdbc.Driver"); }catch(ClassNotFoundException e){ System.out.println("找不到驱动程序类 ，加载驱动失败！"); e.printStackTrace(); } 成功加载后，会将Driver类的实例注册到Driv...

jdbc连接数据库使用sid和service_name的区别 博客分类： oracle 最近使用jdbc连接oracle时报错： ORA-12505, TNS:listener does not currently know of SID given in connect descriptor The Connection descriptor used by the client was: 10.12.162.84:1521:xxxx 登陆oracle数据发现在network/admin/文件夹下的tnsnames.ora中配置的是：SERVICE_NAME =xxxx。经过查询发现，是jdbc中的连接串使用的不正确。Java JDBC Thin Driv...
