JDBC連結MySQL和Oracle

標籤:

  • import java.sql.*;
        JDBC中所要用的包幾乎都在import?java.sql.*;中;
  • 在項目中匯入Oracel或者是MySQL包和裝載驅動:
    項目的ClassPath和系統的ClassPath建議放在ClassPath,如果放在系統的ClassPath中如果版本不同,可能干擾系統中的不同的項目,放在項目下,降低項目之間的耦合性;裝載Oracle驅動:
Class.forName("oracle.jdbc.driver.OracleDriver");
裝載MySQL驅動:
Class.forName("com.mysql.jdbc.Driver");
  • 建立串連:
    1.1、建立Oracle串連:
Connection conn = DriverManager.getConnection("jdbc:mysql://host:port/datebase","user","password");
    2.1、建立MySQL串連:
Connection conn = DriverManager.getConnection("jdbc:mysql://host:port/datebase","user","password");
import java.sql.*;public class TestJDBC {    public static void main(String[] args) throws Exception {                //Class.forName("com.mysql.jdbc.Driver");                long start = System.currentTimeMillis();                new com.mysql.jdbc.Driver();                //Connection conn = DriverManager.getConnection("jdbc:mysql://host:port/datebase","user","password");        Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/martin","root","admin");        //Connection conn = DriverManager.getConnection("jdbc:oracle:[email protected]:port:datebase","user","password");                //System.out.println(conn);                System.out.println(conn);        long end = System.currentTimeMillis();        System.out.println("建立串連耗時: "+(end - start));    }}
