JavaFX程序初次运行创建数据库并执行建表SQL

  在我的第一个JavaFX程序完成安装的时候才突然发现，不能要用这个软件还要手动执行Sql来建表吧？

　于是我的想法是在Main程序中执行时检测数据库连接状况，如果没有检测到数据库或者连接异常，那么出现错误提示，如果数据库连接没有问题那么自动创建数据库并执行建表Sql进行初始化。

package oa.util;

import java.io.IOException;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.Properties;

import org.apache.ibatis.jdbc.ScriptRunner;

import com.ibatis.common.resources.Resources;
import com.mysql.jdbc.Connection;
import com.mysql.jdbc.Statement;

public class CreateMySqlDatabase {

	public static void createDatabase() throws SQLException {
		Connection conn;
		conn = (Connection) DriverManager.getConnection("jdbc:mysql://localhost:3306/", "root", "1234");
		Statement stmt = (Statement) conn.createStatement();
		String sql = "CREATE DATABASE UTILITY";
		stmt.executeUpdate(sql);
	}
	
	
	public static void executeSql() throws IOException, SQLException {
		Properties props = Resources.getResourceAsProperties("mysql.properties");
		String url = props.getProperty("jdbc.url");
		String username = props.getProperty("jdbc.username");
		String password = props.getProperty("jdbc.password");
		Connection conn = (Connection) DriverManager.getConnection(url, username, password);
		ScriptRunner runner = new ScriptRunner(conn);
		runner.setErrorLogWriter(null);
		runner.setLogWriter(null);
		runner.runScript(Resources.getResourceAsReader("sql/utility.sql"));
		conn.close();
		System.out.println("==SUCCESS==");
	}
}

　需要用到 ibatis-common-2.jar读取mysql.properties文件中的JDBC信息。

　MAIN做判断:

try {
			DriverManager.getConnection("jdbc:mysql://localhost:3306/utility", "root", "1234");
			isError = false;
		} catch (MySQLSyntaxErrorException e) {
			primaryStage.setTitle("正在创建Utility数据库……");
			Label error = new Label("正在创建Utility数据库……");
			error.setFont(new Font("Cambria", 100));
			Pane pane = new Pane();
			pane.getChildren().add(error);
			Scene scene = new Scene(pane);
			primaryStage.setScene(scene);
			primaryStage.show();
			try {
				CreateMySqlDatabase.createDatabase();
				CreateMySqlDatabase.executeSql();
				isError = false;
				primaryStage.close();
			} catch (SQLException | IOException e1) {
				primaryStage.close();
				e1.printStackTrace();
			}

		} catch (SQLException se) {
			Thread.sleep(3000);
			primaryStage.close();
			se.printStackTrace();
		}

		if (!isError) {
			run();
		}

	}

	public static void main(String[] args) {
		launch(args);
	}
