Linux(Ubuntu平台)Java通过JDBC连接MySQL数据库,与Windows平台类似,步骤如下:
下载 jdbc: mysql-connector-java-5.1.18.tar.gz
解压 jdbc: tar -zxvf mysql-connector-java-5.1.18.tar.gz
配置 jdbc:cp mysql-connector-java-5.1.18-bin.jar /usr/local/jdk1.6.0_22/jre/lib/ext/

Java示例:
private static String sql=”select top, id, name, country, dtime from gametop800 where id=\”com.rovio.angrybirds\””;
- public mysqlConnect(){
- String dbDriver = “com.mysql.jdbc.Driver”;
- String url = “jdbc:mysql://localhost/top800”;
- String username = “root”;
- String password = “”;
-
- Statement mStatement = null;
- ResultSet mResultSet = null;
- Connection mConnection = null;
-
- String sql = “select top, id, name, country, dtime from gametop800 where top<=20”;
-
- try{
- Class.forName(dbDriver).newInstance();
- mConnection = DriverManager.getConnection(url, username, password);
- mStatement = mConnection.createStatement();
- mResultSet = mStatement.executeQuery(sql);
-
- try{
- while(mResultSet.next()){
- System.out.print(mResultSet.getInt(1) + “\t”);
- System.out.print(mResultSet.getString(2) + “\t”);
- System.out.print(mResultSet.getString(3) + “\t”);
- System.out.println(mResultSet.getString(4));
- }
- }catch (Exception e){
- System.out.println(“数据库读取错误! \n” + e.getMessage());
- }
- }catch (SQLException e){
- System.out.println(“连接数据库错误: \n” + url + “\n” + e.getMessage());
- }catch (Exception e){
- e.printStackTrace();
- }finally{
- // mStatement.close();
- // mConnection.close();
- }
- }
执行结果:
