我用MyEclipse导入了mysql驱动程序
但是在写完这句时DriverManager.registerDriver(new com.mysql.jdbc.Driver());
出现了com.mysql cannot be resolved to a type的错误提示
怎么解决

DriverManager.registerDriver(new com.mysql.jdbc.Driver()); 这个要引入你的MYSQL的启动包。方法同一楼的
不推荐用这种方法注册驱动,而用Class.forName("com.mysql.jdbc.Driver")
这样,即使你没有导入驱动包,但可以编译通过(只是预编译哦)。
