问题描述
在阅读了H2 文档后,我写了这个简单的应用程序来创建H2数据库在本地目录中:
after reading the H2 documentation, I wrote this simple application to create a H2 database in a local directory:
public static void main(String[] args) throws SQLException {
String path = "C:/Temp/H2/";
File fpath = new File(path);
fpath.mkdirs();
FileUtils.recursiveDelete(fpath);
String dbName = "tata";
String connection = "jdbc:h2:file:" + path + dbName;
Server server = Server.createTcpServer(connection);
server.start();
server.stop();
}
这个程序运行正常,但是当我检入目标目录,数据库不存在...(我使用的是版本1.3.161)
This program runs fine, but when I check in the target directory, the database is not there... (i am using release 1.3.161)
推荐答案
数据库,文件创建懒惰:
You need to actually access the database, files are created lazily:
server.start();
DriverManager.getConnection(connection);
server.stop();
中间添加的行创建 tata.h2.db
file where expected(testing with 1.3.155)。
Added line in the middle creates tata.h2.db
file where expected (tested with 1.3.155).
