java.sql.SQLException: No suitable driver

 

 找了N久未解决，在群里经过几个牛人们指点终于搞点，现总结如下

 

 1 驱动包用的不对

 

 2 连接串的写法不同于2000

 

  

 

 //JDBC for SQL server 2000写法：  
 
 String DBDRIVER = "com.microsoft.jdbc.sqlserver.SQLServerDriver";  
 
 //JDBC for SQL server 2005写法：  
 

 String DBDRIVER = "com.microsoft.sqlserver.jdbc.SQLServerDriver";

 

  

 

 
 2003 写法
 
 access.url=jdbc:microsoft:sqlserver://192.168.1.136:1433;DatabaseName=GameDB
 
 2005 写法
 
  String dbURL = "jdbc:sqlserver://localhost:1433; DatabaseName=dbName"; 
 

  

 

 附用的配置文件(2005)

 

 -------------

 

 drivers=com.microsoft.sqlserver.jdbc.SQLServerDriver
 
 logfile=./logs/dblog.txt
 
 access.maxconn=50
 
 access.url=jdbc:sqlserver://192.168.1.136:1433;DatabaseName=Game23DB
 
 access.user=sa
 
 access.password=hujie
 

 -------附属性文件建立及dbcontect-----

 
用配置文件连接数据库
1. Eclipse中，在src目录下建立db.properties文件，在里面配置数据库连接所需的      Driver,url,user,possword ，注意等号左右不能空格
  
  如：
 driver=com.microsoft.sqlserver.jdbc.SQLServerDriver
 url=jdbc:sqlserver://localhost:1433;databaseName=restrant
 user=sa
 password=110 2.写一个数据库连接类
import java.io.IOException;
 import java.sql.*;
 import java.util.Properties; public Connection getCon() 
   Connection con = null;
   Properties properties = new Properties();
   try 
    properties.load(this.getClass().getResourceAsStream(
      "/db.properties"));
    String driver = properties.getProperty("driver");
    String url = properties.getProperty("url");
    String user = properties.getProperty("user");
    String password = properties.getProperty("password");   try 
     Class.forName(driver);
     con = DriverManager.getConnection(url, user, password);
     catch (ClassNotFoundException e) 
     // TODO Auto-generated catch block
     e.printStackTrace();
     catch (SQLException e) 
     // TODO Auto-generated catch block
     e.printStackTrace();
    
    catch (IOException e) 
    // TODO Auto-generated catch block
    e.printStackTrace();
   
   return con;
   

 sql 2000 需要引用三个jar包 msbase.jar,mssqlserver.jar,msutil.jar

 

 sql 2005 需要引用一个jar包 sqljdbc.jar
