H2内嵌数据库使用步骤

1、找到h2数据库的jar包

D:\repositories\com\h2database\h2\1.4.187\h2-1.4.187.jar

2、双击jar包，配置连接信息

Driver Class：org.h2.Driver

JDBC URL：jdbc:h2:file:~/.h2/sample;AUTO_SERVER=TRUE;DB_CLOSE_DELAY=-1（与application.properties相同，但掉"log4jdbc:"）

3、点击连接，在T_USER表中插入一条数据

insert into t_user (ID, EMAIL, NAME, PASSWORD, ROLE, SALT, SEX)

values ('fbe00c9e-97b0-49f9-9f3d-3431050dec74', 'xy.hero@qq.com', 'admin', '4c1e9c2a03a6f49db3bde4699fcb98fe5f1203b8', 'admin', '9c14b4497360e049', '1');

新建h2数据库

指定JDBC URL：jdbc:h2:E://research//workspace//H2Test//db//test，点击connect，会看到e盘多出一个文件夹research

执行test语句，创建test表

测试类

package cn.itcast.test;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
/**
 * H2测试类

public class TestH2 {

    public static void main(String[] args) throws ClassNotFoundException, SQLException{
        Class.forName("org.h2.Driver");
        Connection conn = DriverManager.getConnection("jdbc:h2:E://research//workspace//H2Test//db//test", "sa", "");
        Statement stmt = conn.createStatement();

        ResultSet rs = stmt.executeQuery("select * from test");
        while(rs.next()){
            System.out.println(rs.getInt("ID")+","+rs.getString("NAME"));
        }
        conn.close();
    }
}
