Question

实际上我需要将文件从本地传输到FTP服务器。

    ComPtr<IMouseCapabilities> caps;
    HRESULT hr = RoActivateInstance(HStringReference(RuntimeClass_Windows_Devices_Input_MouseCapabilities).Get(), &caps);

这里输入流得到a.xt＆amp;来自test-file文件夹的b.txt文件（它位于项目src / main / resource中）

ConfigurableApplicationContext ctx = new ClassPathXmlApplicationContext("META-INF/spring/integration/FtpOutboundChannelAdapterSample-context.xml");

MessageChannel ftpChannel = ctx.getBean("ftpChannel", MessageChannel.class);
final File baseFolder = new File("target" + File.separator + "toSend");
            baseFolder.mkdirs();
final File fileToSendA = new File(baseFolder, "a.txt");
final File fileToSendB = new File(baseFolder, "b.txt");

这些都很有效。

但我的问题是如何从本地目录获取文件＆amp;我试过了：

final InputStream inputStreamA = FtpOutboundChannelAdapterSample.class.getResourceAsStream("/test-files/a.txt");
final InputStream inputStreamB = FtpOutboundChannelAdapterSample.class.getResourceAsStream("/test-files/b.txt");

FileUtils.copyInputStreamToFile(inputStreamA, fileToSendA);
FileUtils.copyInputStreamToFile(inputStreamB, fileToSendB);

final Message<File> messageA = MessageBuilder.withPayload(fileToSendA).build();
final Message<File> messageB = MessageBuilder.withPayload(fileToSendB).build();

ftpChannel.send(messageA);
ftpChannel.send(messageB);

Thread.sleep(2000);

System.out.println("Successfully transfered file 'a.txt' and 'b.txt' to a remote FTP location.");
ctx.close();

我正在final InputStream inputStreamA = FtpOutboundChannelAdapterSample.class.getResourceAsStream("D:/Test-download/a.txt");。

我的xml是

NullPointerException

如何从spring集成ftp outboundchannel中的本地目录中获取文件？
