Jackcess 2.x的更新：现在使用来创建(或打开)DatabaseBuilder数据库，因此我们要创建一个新的数据库文件

import java.io.File;

import java.io.IOException;

import com.healthmarketscience.jackcess.Database;

import com.healthmarketscience.jackcess.Database.FileFormat;

import com.healthmarketscience.jackcess.DatabaseBuilder;

public class JackcessDemoMain {

public static void main(String[] args) {

String dbPath = "C:/Users/Public/newDb.accdb";

// using try-with-resources is recommended to ensure that

// the Database object will be closed properly

try (Database db = DatabaseBuilder.create(FileFormat.V2010, new File(dbPath))) {

System.out.println("The database file has been created.");

} catch (IOException ioe) {

ioe.printStackTrace(System.err);

}

}

}

Jackcess 1.x的原始答案(不建议使用)：

如果要通过Java创建“ .mdb”文件，则可以使用Jackcess Java库，该库是用于读取和写入MS

Access数据库的纯Java库之一。我猜目前支持的版本包括2000-2007。请看以下示例，以更好地理解：

package com.jackcess.lib;

import com.healthmarketscience.jackcess.ColumnBuilder;

import com.healthmarketscience.jackcess.Database;

import com.healthmarketscience.jackcess.Table;

import com.healthmarketscience.jackcess.TableBuilder;

import java.io.File;

import java.io.IOException;

import java.sql.SQLException;

import java.sql.Types;

/**

public class JackcessLibrary {

private static Database createDatabase(String databaseName) throws IOException {

return Database.create(new File(databaseName));

}

private static TableBuilder createTable(String tableName) {

return new TableBuilder(tableName);

}

public static void addColumn(Database database, TableBuilder tableName, String columnName, Types sqlType) throws SQLException, IOException {

tableName.addColumn(new ColumnBuilder(columnName).setSQLType(Types.INTEGER).toColumn()).toTable(database);

}

public static void startDatabaseProcess() throws IOException, SQLException {

String databaseName = "C:/Users/compaq/Desktop/employeedb.mdb"; // Creating an MS Access database

Database database = createDatabase(databaseName);

String tableName = "Employee"; // Creating table

Table table = createTable(tableName)

.addColumn(new ColumnBuilder("Emp_Id").setSQLType(Types.INTEGER).toColumn())

.addColumn(new ColumnBuilder("Emp_Name").setSQLType(Types.VARCHAR).toColumn())

.addColumn(new ColumnBuilder("Emp_Employer").setSQLType(Types.VARCHAR).toColumn())

.toTable(database);

table.addRow(122875, "Sarath Kumar Sivan","Infosys Limited.");//Inserting values into the table

}

public static void main(String[] args) throws IOException, SQLException {

JackcessLibrary.startDatabaseProcess();

}

}
