HSQLDB内存模式在关机时不会删除文件

问题描述

限时删除！！

出于测试目的，我正在使用HSQLDB 2.2.9版.当我在内存数据库中创建命名的文件时，调用shutdown函数后不会删除文件.在我的文件系统上，我有文件夹DBname.tmp和文件DBname.lck，DBname.log，DBname.properties和DBname.script.据我了解，文档( http://hsqldb.org/doc/2.0/guide/dbproperties-chapt.html#dpc_connection_url )应该不会发生.

I'm using HSQLDB version 2.2.9 for testing purposes.When I create named in memory database, files aren't deleted after calling shutdown function. On my filesystem I have folder DBname.tmp and files DBname.lck, DBname.log, DBname.properties and DBname.script. As I understand documentation (http://hsqldb.org/doc/2.0/guide/dbproperties-chapt.html#dpc_connection_url) it shouldn't happened.

为了进行测试，我使用以下代码:

For testing I'm using the following code:

import java.io.IOException;
import org.hsqldb.Server;
import org.hsqldb.persist.HsqlProperties;
import org.hsqldb.server.ServerAcl.AclFormatException;
import org.junit.Test;

public class HSQLDBInMemTest {

    @Test
    public void test() throws IOException, AclFormatException {
        HsqlProperties props = new HsqlProperties();
        props.setProperty("server.database.0", "test1");
        props.setProperty("server.dbname.0", "test1");

        props.setProperty("server.database.1", "test2");
        props.setProperty("server.dbname.1", "test2");
        Server hsqlServer = new Server();
        hsqlServer.setRestartOnShutdown(false);
        hsqlServer.setNoSystemExit(true);
        hsqlServer.setProperties(props);
        hsqlServer.start();

        hsqlServer.shutdown();
    }
}

推荐答案

在这里回答:通过 fredt

代码应类似于:

import java.io.IOException;
import org.hsqldb.Server;
import org.hsqldb.persist.HsqlProperties;
import org.hsqldb.server.ServerAcl.AclFormatException;
import org.junit.Test;

public class HSQLDBInMemTest {

@Test
public void test() throws IOException, AclFormatException {
    HsqlProperties props = new HsqlProperties();
    props.setProperty("server.database.0", "mem:test1");

    props.setProperty("server.database.1", "mem:test2");
    Server hsqlServer = new Server();
    hsqlServer.setRestartOnShutdown(false);
    hsqlServer.setNoSystemExit(true);
    hsqlServer.setProperties(props);
    hsqlServer.start();

    hsqlServer.shutdown();
}
}

内存数据库的路径类似于 props.setProperty("server.database.0"，"mem:test1");

The path for a memory database looks like props.setProperty("server.database.0", "mem:test1");
