java连sql server 菜鸟问题
import java.sql.*;public class TestDB {
public static void main(String[] args) {
String driverName = "com.microsoft.jdbc.sqlserver.SQLServerDriver";
String dbURL = "jdbc:microsoft:sqlserver://localhost:1433; DatabaseName=pubs";
String userName = "sa";
String userPwd = "";
Connection dbConn;
try {
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
dbConn = DriverManager.getConnection(dbURL, userName, userPwd);
System.out.println("Connection Successful!");
} catch (Exception e) {
e.printStackTrace();
}
}
}
如何才能连上呢？？？
运行结果：
java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver
