您可以使用MySQL数据库。
1）下载mysql连接器，然后将jar添加到您的项目中。
2）在db中创建一个表，并使用该表在其中插入值。
数据库的Java代码
public class Database { private Connection connection = null; private Statement statement = null; private String serverName = null; private String dbName = null; private String dbtablename = null; private String username = null; private String password = null; public Database() { serverName = //your value; dbName = your value dbtablename = //your value username = //your value password = //your value } public Connection OpenConnectionDB() { try { Class.forName("com.mysql.jdbc.Driver").newInstance(); this.connection = DriverManager.getConnection("jdbc:mysql://" + serverName + "/" + dbName + "?useUnipre=yes&characterEncoding=UTF-8&" + "user=" + username + "&password=" + password); System.out.println("conection: " + connection); // this.connection = DriverManager.getConnection("jdbc:mysql://" + serverName + "/" + dbName +"?user=" + username + "&password=" + password ); //System.out.println("debug: Connect to dbServer"); } catch (SQLException ex) { Logger.getLogger(Database.class.getName()).log(Level.SEVERE, null, ex); } catch (InstantiationException ex) { Logger.getLogger(Database.class.getName()).log(Level.SEVERE, null, ex); } catch (IllegalAccessException ex) { Logger.getLogger(Database.class.getName()).log(Level.SEVERE, null, ex); } catch (ClassNotFoundException ex) { Logger.getLogger(Database.class.getName()).log(Level.SEVERE, null, ex); } return connection; } public void closeConnectionDB() { if (this.connection != null) { try { connection.close(); connection = null; //System.out.println("debug: Close dbServer"); } catch (SQLException ex) { System.out.println("debug: Closing Database... FAILED (NOT RUNNING)"); Logger.getLogger(Database.class.getName()).log(Level.SEVERE, null, ex); } } } public void insert(){ String query = //your insert query OpenConnectionDB(); try { this.statement = this.connection.createStatement(); this.statement.execute(query); statement.close(); } catch (SQLException ex) { Logger.getLogger(Database.class.getName()).log(Level.SEVERE, null, ex); } closeConnectionDB(); } public String getResults(){ String query = //select query OpenConnectionDB(); try { this.statement = this.connection.createStatement(); ResultSet rs = this.statement.executeQuery(query); if(rs!=null){ while(rs.next()){ return rs.getString("Your_field_name_in_db"); //get your } } statement.close(); } catch (SQLException ex) { Logger.getLogger(Database.class.getName()).log(Level.SEVERE, null, ex); } closeConnectionDB(); return null; }}编辑 您也可以使用MySQL
WorkBench处理您的数据库。
