我正在使用JCraft的JSch库作为我的程序的FTP客户端,它工作正常。但是我在创建用于单元测试的模拟(MockFtpServer)时遇到了困难。
import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
import org.junit.AfterClass;

import org.mockftpserver.fake.FakeFtpServer;
import org.mockftpserver.fake.UserAccount;
import org.mockftpserver.fake.filesystem.FileEntry;
import org.mockftpserver.fake.filesystem.FileSystem;
import org.mockftpserver.fake.filesystem.UnixFakeFileSystem;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import java.util.Properties;
@RunWith(SpringRunner.class)
@SpringBootTest
public class SFTPManagerTest {
static FakeFtpServer fakeFtpServer;
@BeforeClass
public static void startFTP() throws Exception {
fakeFtpServer = new FakeFtpServer();
fakeFtpServer.setServerControlPort(9999);
FileSystem fileSystem = new UnixFakeFileSystem();
fileSystem.add(new FileEntry("/data/JFS_HCID_APPLICATION_STATUS_20190109.TXT", "<schema/>"));
fakeFtpServer.setFileSystem(fileSystem);
UserAccount userAccount = new UserAccount("user", "password", "/");
fakeFtpServer.addUserAccount(userAccount);
fakeFtpServer.start();
}
@Test
public void getFileListing() {
try {
JSch jsch = new JSch();
Session jschSession = jsch.getSession("user", "localhost", 9999);
jschSession.setPassword("password");
Properties config = new Properties();
config.put("StrictHostKeyChecking", "no");
jschSession.setConfig(config);
jschSession.connect();
Channel jschChannel = jschSession.openChannel("ftp");
jschChannel.connect();
ChannelSftp channel = (ChannelSftp) jschChannel;
Vector v = channel.ls("/data");
Assert.assertNotNull(v);
} catch (Exception ex) {
ex.printStackTrace();
}
}
@AfterClass
public static void stopFTP() {
fakeFtpServer.stop();
}
}
依赖关系:
输出:在执行测试方法期间始终卡住/停止,而不是完成。卡住/停止时,我可以使用WinSCP或FTP CLI访问MockFtpServer。从日志中可以看出JSch的命令无法识别。

我哪里做错了?
JSch是一个SSH / SFTP库。您无法使用FTP服务器进行测试。您需要使用SFTP服务器。 FTP和SFTP是两个完全不相关且不同的协议。
