hxtt DBF 驱动程序锁定其文件
我的网络应用程序接收存档，将其解压到临时文件夹，从提取的 DBF 中读取数据，然后应该清除垃圾。尽管它无法杀死临时文件夹，因为其中的 DBF 文件被锁定。这是示例代码：
<代码> public static void main( String a[] ) 抛出异常 {
Class.forName( "com.hxtt.sql.dbf.DBFDriver" ).newInstance();
String url = "jdbc:DBF:/C:/TEMP/";
Properties properties = new Properties();
properties.setProperty( "charSet", "cp866" );
Connection con = null;
Statement st = null;
java.sql.Driver d = null;
con = DriverManager.getConnection( url, properties );
d = DriverManager.getDriver( url );
st = con.createStatement();
ResultSet rs = st.executeQuery( "SELECT * FROM 6QQQ201010" );
rs.close();
st.close();
con.close();
<代码>}
我将断点放在最后一行之后，6QQQ201010.DBF 仍然被锁定。有什么想法吗？或者只是驱动程序中的一个错误？
My web app receives archive, unpacks it to temp folder, reads data from extracted DBFs and then should kill garbage. Though it fails to kill temp folder since DBF files in it are locked. Here is a sample code:
public static void main( String a[] ) throws Exception
{
Class.forName( "com.hxtt.sql.dbf.DBFDriver" ).newInstance();
String url = "jdbc:DBF:/C:/TEMP/";
Properties properties = new Properties();
properties.setProperty( "charSet", "cp866" );
Connection con = null;
Statement st = null;
java.sql.Driver d = null;
con = DriverManager.getConnection( url, properties );
d = DriverManager.getDriver( url );
st = con.createStatement();
ResultSet rs = st.executeQuery( "SELECT * FROM 6QQQ201010" );
rs.close();
st.close();
con.close();
}
I put breakpoint past last line and 6QQQ201010.DBF is still locked. Any ideas? Or just a bug in the driver?

添加properties.setProperty( "delayedClose", "0" );司机会立即关闭手柄。
Add properties.setProperty( "delayedClose", "0" ); and driver would close handles imediately.
