内存数据库H2使用

1）一个jar包，一个bat脚本：



2）点击h2.bat:



3) 使H2数据库 可以远程连接：



4）java调用：

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.sql.Statement;

import org.h2.tools.Server;

public class H2Demo {

private Server server;

private String port = "8082";

private String dbDir = "jdbc:h2:tcp://192.168.0.36/~/test";

private String user = "sa";

private String password = "";

public void startServer() {

try {

System.out.println("正在启动h2...");

server = Server.createTcpServer(

new String[] { "-tcpPort", port }).start();

} catch (SQLException e) {

System.out.println("启动h2出错：" + e.toString());

e.printStackTrace();

throw new RuntimeException(e);

}

}

public void stopServer() {

if (server != null) {

System.out.println("正在关闭h2...");

server.stop();

System.out.println("关闭成功.");

}

}

public void useH2() {

try {

Class.forName("org.h2.Driver");

Connection conn = DriverManager.getConnection(dbDir,

user, password);

Statement stat = conn.createStatement();

// insert data

// stat.execute("CREATE TABLE TEST(NAME VARCHAR)");

stat.execute("INSERT INTO TEST VALUES('Hello World')");

// use data

ResultSet result = stat.executeQuery("select name from test ");

int i = 1;

while (result.next()) {

System.out.println(i++ + ":" + result.getString("name"));

}

result.close();

stat.close();

conn.close();

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

public static void main(String[] args) {

H2Demo h2 = new H2Demo();

// h2.startServer();

h2.useH2();

// h2.stopServer();

System.out.println("==END==");

}

}
