我是Spring集成的新手,所以它对专家来说可能是愚蠢的。
我想每天早上在SFTP服务器上读取一个excel文件(目前我设置为每分钟读取一次,如下所示)。我已经写了所有的代码,收到的excel的输入流和使用POI遍历它。
如果我给文件手动从JSP上传,那么没有问题,一切都很好。
但是当我使用下面的代码启用spring集成时,它会给我错误。
我发现"DefaultSftpSessionFactory“对"jsch-0.1.51.jar”有内在的依赖关系,这也是我手工绑定的一部分。
我使用的是spring 4.0.9。
仅供参考,控件在我的"processFTPFile“方法之前是不会出现的。
<bean id="ultiProSftpSessionFactory" class="org.springframework.integration.sftp.session.DefaultSftpSessionFactory">
<property name="host" value="serverhost" />
<property name="user" value="user" />
<property name="password" value="password" />
</bean>
<int-ftp:inbound-channel-adapter id="ftpInboundChannelAdapter" session-factory="ultiProSftpSessionFactory" channel="fileAvailableChannel"
filename-pattern="* Consolidated Report.xlsx"
remote-directory="/folder1/folder2"
preserve-timestamp="true"
local-directory="."
auto-create-local-directory="true"
delete-remote-files="false"
auto-startup="true">
<int:poller cron="0 0/1 * * * *">
</int:poller>
</int-ftp:inbound-channel-adapter>
<int:service-activator id="serviceUpdateTrackingItem" method="processFTPFile" ref="cAPunchDataAdapter" input-channel="fileAvailableChannel" />
<int:publish-subscribe-channel id="fileAvailableChannel"/>
我想在每个文件上执行的代码
@Component("cAPunchDataAdapter")
public class CAPunchDataAdapter {
public void processFTPFile(FTPFile file) {
//Code goes here to get inputstream of file.
}
}
下面是错误日志。

JSch是用于ftp的,您正在使用ftp。
你需要
<int-sftp:inbound-channel-adapter id="ftpInboundChannelAdapter" session-factory="ultiProSftpSessionFactory" channel="fileAvailableCh
(int-sftp:
,而不是int-ftp:
)

找到了修复方法,我就没想到会这样了。
已替换
<int-ftp:inbound-channel-adapter
使用
<int-sftp:inbound-channel-adapter
Spring应该实现更好的错误消息:)。
