我正在尝试使用Apache FTPServer建立基于Windows的FTP服务器，但是每当我使用db-user-manager而不是文件用户管理器时，我都会遇到同样的问题。我们的数据库中有近6,000个用户要迁移到Windows，因此文件用户管理器不够用（因为大小是IMMENSE）。我已经使用WAMP创建了本地SQL服务器，并将其设置为Apache FTP使用，并且有一个脚本来每天查询/复制/组织远程数据库中的用户到本地用户。
我遇到的问题是，无论出于何种原因，每当我运行程序时，Apache FTPServer都会一直给我以下错误：
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 27 in XML document from file [c:\apache-ftpserver-1.0.5\res\conf\ftpd-full.xml] is invalid;

我从http://commons.apache.org/dbcp/下载了正确的DBCP基本数据源文件，从http://dev.mysql.com/downloads/connector/j/下载了mysql连接器(version 5.1.6 at that time)，并按照说明将所有文件放入common \ lib文件夹中。
我确保删除其他用户管理代码“file-user-manager”
我仍然不明白......为什么不起作用？
这是我的xml文件：

答案 0 :(得分：2)
它不是DBCP问题，它是一个Spring配置问题。更改XML文件的顶部以包含spring bean定义，我认为你没事。
<server xmlns="http://mina.apache.org/ftpserver/spring/v1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:beans="http://www.springframework.org/schema/beans"
xsi:schemaLocation="
http://mina.apache.org/ftpserver/spring/v1 http://mina.apache.org/ftpserver/ftpserver-1.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"
id="Prometheus">
您可能需要将2.0.xsd最后更改为3.0.xsd，具体取决于MINA FTPServer附带的Spring版本。
答案 1 :(得分：2)
代替（或除了）commons-pool-1.6（上面的链接），安装在common/lib commons-dbcp-1.4 3个jar文件中。
http://commons.apache.org/dbcp/download_dbcp.cgi
这对我有用。
