mysql4.1.10的JDBC驅動的配置及測試
一.下載
mysql4.1.10的下載:
http://dev.mysql.com/get/Downloads/MySQL-4.1/mysql-4.1.10-win32.zip/from/pickmysql4.1.10jdbc驅動的下載:
http://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-3.1.7.zip/from/pickmysql-front的下載:
MySQL-Front is an easy to use, compact, and very fast graphical tool to manage your MySQL database - from anywhere in the world. http://www.mysqlfront.de/download.html二.配置
1. 把下載的jdbc驅動mysql-connector-java-3.1.7.zip解壓縮,提取其中的mysql-connector-java-3.1.7-bin.jar文件到適當位置,并設置classpath路徑指向該文件.
2.安裝mysql數據庫.
3.安裝mysql-front,利用mysql-front建立數據庫jtest,并在jtest中建立表info.然后填入數據.
三.測試
測試代碼如下:
文件名:testMysql.java
/**
* @author rockaka
* mysql的jdbc驅動測試代碼
* mysql4.1.10+mysql-connector-java-3.1.7-bin.jar
* data:2005-02-23
*/
import java.sql.*;
public class testMysql {
public static void main(String[] args) {
//驅動程序名
String driverName="com.mysql.jdbc.Driver";
//數據庫用戶名
String userName="root";
//密碼
String userPasswd="root";
//數據庫名
String dbName="jtest";
//表名
String tableName="info";
//聯結字符串
String url="jdbc:mysql://localhost/"+dbName+"?user="+userName+"&password="+userPasswd;
System.out.println(url);
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection connection=DriverManager.getConnection(url);
Statement statement = connection.createStatement();
String sql="SELECT * FROM "+tableName;
ResultSet rs = statement.executeQuery(sql);
// 獲得數據結果集合
ResultSetMetaData rmeta = rs.getMetaData();
// 確定數據集的列數，亦字段數
int numColumns=rmeta.getColumnCount();
// 輸出每一個數據值
for(int i=1;i<=numColumns;i++) {
if(i<numColumns)
System.out.print(rmeta.getColumnName(i)+" | ");
else
System.out.println(rmeta.getColumnName(i));
}
while(rs.next()){
for(int i=1;i<=numColumns;i++) {
if(i<numColumns)
System.out.print(rs.getString(i).trim()+" | ");
else
System.out.println(rs.getString(i).trim());
}
}
rs.close();
connection.close();
}catch(Exception ex){
System.out.println(ex);
System.exit(0);
}
}
}
四:編譯與運行
1.編譯:javac testMysql.java
2.運行:java testMysql
3.我的運行結果:
jdbc:mysql://localhost/jtest?user=root&password=root
