Question

我的网络应用程序接收存档，将其解压缩到临时文件夹，从提取的DBF中读取数据然后应该杀死垃圾。虽然它无法杀死临时文件夹，因为其中的DBF文件已被锁定。以下是示例代码：

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();

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();

我把断点放在最后一行和6QQQ201010.DBF仍然被锁定。有任何想法吗？或者只是驱动程序中的错误？

添加properties.setProperty（“delayedClose”，“0”）;并且司机会立即关闭句柄。

hxtt DBF驱动程序锁定其文件
