import java.sql.Connection;import java.sql.DriverManager;import java.sql.SQLException;public class ConDB{    private static Connection getConnection() {        Connection conn = null;        try {                      String url = "jdbc:db2://192.168.1.254:50000/TEST";               String driver = "com.ibm.db2.jcc.DB2Driver";               String uid = "db2admin";              String pwd = "123456";               Class.forName(driver);            conn = DriverManager.getConnection(url, uid, pwd);            return conn;        } catch (ClassNotFoundException e) {            System.out.println("driver wrong Problem~");            e.printStackTrace();        } catch (SQLException e) {            e.printStackTrace();        }        return null;    }    public static void main(String[] args) {        try {            // create data source            Connection conn = null;            conn = getConnection();            System.out.println("连接成功");                   } catch (Exception e) {            e.printStackTrace();        }    }}
