Question

我正在尝试将文件发送到远程SFTP服务器。 我已经为它创建了一个工厂和一个outboundFlow。

UploaderSftpConnectionFactoryBuilder

@Configuration
public class UploaderSftpConnectionFactoryBuilder {

@Value("${report-uploader.sftp-factory.host}")
private String host = null;
@Value("${report-uploader.sftp-factory.port}")
private Integer port = null;
@Value("classpath:${report-uploader.sftp-factory.privateKey}")
private Resource privateKey = null;
@Value("${report-uploader.sftp-factory.privateKeyPassphrase}")
private String privateKeyPassphrase = null;
@Value("${report-uploader.sftp-factory.maxConnections}")
private String maxConnections = null;
@Value("${report-uploader.sftp-factory.user}")
private String user = null;
@Value("${report-uploader.sftp-factory.poolSize}")
private Integer poolSize = null;
@Value("${report-uploader.sftp-factory.sessionWaitTimeout}")
private Long sessionWaitTimeout = null;

//@Bean(name = "cachedSftpSessionFactory")
public DefaultSftpSessionFactory getSftpSessionFactory() {
    DefaultSftpSessionFactory defaultSftpSessionFactory = new DefaultSftpSessionFactory();

    Optional.ofNullable(this.getHost()).ifPresent(value -> defaultSftpSessionFactory.setHost(value));
    Optional.ofNullable(this.getPort()).ifPresent(value -> defaultSftpSessionFactory.setPort(port));
    Optional.ofNullable(this.getPrivateKey()).ifPresent(
            value -> defaultSftpSessionFactory.setPrivateKey(privateKey));
    Optional.ofNullable(this.getPrivateKeyPassphrase()).ifPresent(
            value -> defaultSftpSessionFactory.setPrivateKeyPassphrase(value));
    Optional.ofNullable(this.getUser()).ifPresent(value -> defaultSftpSessionFactory.setUser(value));

    return defaultSftpSessionFactory;
}

@Bean(name = "cachedSftpSessionFactory")
public CachingSessionFactory<LsEntry> getCachedSftpSessionFactory() {
    CachingSessionFactory<LsEntry> cachedFtpSessionFactory = new CachingSessionFactory<LsEntry>(
            getSftpSessionFactory());
    cachedFtpSessionFactory.setPoolSize(poolSize);
    cachedFtpSessionFactory.setSessionWaitTimeout(sessionWaitTimeout);
    return cachedFtpSessionFactory;
}

public String getHost() {
    return host;
}

public void setHost(String host) {
    this.host = host;
}

public Resource getPrivateKey() {
    return privateKey;
}

public void setPrivateKey(Resource privateKey) {
    this.privateKey = privateKey;
}

public String getPrivateKeyPassphrase() {
    return privateKeyPassphrase;
}

public void setPrivateKeyPassphrase(String privateKeyPassphrase) {
    this.privateKeyPassphrase = privateKeyPassphrase;
}

public String getMaxConnections() {
    return maxConnections;
}

public void setMaxConnections(String maxConnections) {
    this.maxConnections = maxConnections;
}

public Integer getPort() {
    return port;
}

public void setPort(Integer port) {
    this.port = port;
}

public String getUser() {
    return user;
}

public void setUser(String user) {
    this.user = user;
}

}

现在，我想使用集成测试来测试出站流。 为此，我创建了以下testContext：

TestContextConfiguration

@Configuration
public class TestContextConfiguration {
@Configuration
@Import({ FakeSftpServer.class, JmxAutoConfiguration.class, IntegrationAutoConfiguration.class,
        UploaderSftpConnectionFactoryBuilder.class })
@IntegrationComponentScan
public static class ContextConfiguration {

    @Value("${report-uploader.reportingServer.fileEncoding}")
    private String fileEncoding;

    @Autowired
    private FakeSftpServer fakeSftpServer;

    @Autowired
    @Qualifier("cachedSftpSessionFactory")
    //CachingSessionFactory<LsEntry> cachedSftpSessionFactory;
    DefaultSftpSessionFactory cachedSftpSessionFactory;

    @Bean
    public IntegrationFlow sftpOutboundFlow() {
        return IntegrationFlows
                .from("toSftpChannel")
                .handle(Sftp.outboundAdapter(this.cachedSftpSessionFactory, FileExistsMode.REPLACE)
                        .charset(Charset.forName(fileEncoding)).remoteFileSeparator("\\")
                        .remoteDirectory(this.fakeSftpServer.getTargetSftpDirectory().getPath())
                        .fileNameExpression("payload.getName()").autoCreateDirectory(true)
                        .useTemporaryFileName(true).temporaryFileSuffix(".tranferring")
                        ).get();
    }

    @Bean
    public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
    }

}

我还根据建议创建了一个伪造的sftp服务器@ https://github.com/spring-projects/spring-integration-java-dsl/blob/master/src/test/java/org/springframework/integration/dsl/test /sftp/TestSftpServer.java下面是我的假服务器：

FakeSftpServer

@Configuration("fakeSftpServer")
public class FakeSftpServer implements InitializingBean, DisposableBean {

    private final SshServer server = SshServer.setUpDefaultServer();

    private final int port = SocketUtils.findAvailableTcpPort();

    private final TemporaryFolder sftpFolder;

    private final TemporaryFolder localFolder;

    private volatile File sftpRootFolder;

    private volatile File sourceSftpDirectory;

    private volatile File targetSftpDirectory;

    private volatile File sourceLocalDirectory;

    private volatile File targetLocalDirectory;

    public FakeSftpServer() {
            this.sftpFolder = new TemporaryFolder() {

                    @Override
                    public void create() throws IOException {
                            super.create();
                            sftpRootFolder = this.newFolder("sftpTest");
                            targetSftpDirectory = new File(sftpRootFolder, "sftpTarget");
                            targetSftpDirectory.mkdir();
                    }
            };

            this.localFolder = new TemporaryFolder() {

                    @Override
                    public void create() throws IOException {
                            super.create();
                            File rootFolder = this.newFolder("sftpTest");
                            sourceLocalDirectory = new File(rootFolder, "localSource");
                            sourceLocalDirectory.mkdirs();
                            File file = new File(sourceLocalDirectory, "localSource1.txt");
                            file.createNewFile();
                            file = new File(sourceLocalDirectory, "localSource2.txt");
                            file.createNewFile();

                            File subSourceLocalDirectory = new File(sourceLocalDirectory, "subLocalSource");
                            subSourceLocalDirectory.mkdir();
                            file = new File(subSourceLocalDirectory, "subLocalSource1.txt");
                            file.createNewFile();

                    }
            };
    }

    @Override
    public void afterPropertiesSet() throws Exception {
            this.sftpFolder.create();
            this.localFolder.create();

            this.server.setPasswordAuthenticator((username, password, session) -> true);
            this.server.setPort(this.port);
            this.server.setKeyPairProvider(new SimpleGeneratorHostKeyProvider(new File("src/test/resources/hostkey.ser")));
            this.server.setSubsystemFactories(Arrays.<NamedFactory<Command>>asList(new SftpSubsystemFactory()));
            this.server.setFileSystemFactory(new VirtualFileSystemFactory(sftpRootFolder.toPath()));
            this.server.start();
    }

    @Override
    public void destroy() throws Exception {
            this.server.stop();
            this.sftpFolder.delete();
            this.localFolder.delete();
    }

    public File getSourceLocalDirectory() {
            return this.sourceLocalDirectory;
    }

    public File getTargetLocalDirectory() {
            return this.targetLocalDirectory;
    }

    public String getTargetLocalDirectoryName() {
            return this.targetLocalDirectory.getAbsolutePath() + File.separator;
    }

    public File getTargetSftpDirectory() {
            return this.targetSftpDirectory;
    }

    public void recursiveDelete(File file) {
            File[] files = file.listFiles();
            if (files != null) {
                    for (File each : files) {
                            recursiveDelete(each);
                    }
            }
            if (!(file.equals(this.targetSftpDirectory) || file.equals(this.targetLocalDirectory))) {
                    file.delete();
            }
    }
}

最后是我的测试课

TestConnectionFactory

@ContextConfiguration(classes = { TestContextConfiguration.class }, initializers = {ConfigFileApplicationContextInitializer.class})
@RunWith(SpringJUnit4ClassRunner.class)
@DirtiesContext
public class TestConnectionFactory {

@Autowired
@Qualifier("cachedSftpSessionFactory")
CachingSessionFactory<LsEntry> cachedSftpSessionFactory;
//DefaultSftpSessionFactory cachedSftpSessionFactory;

@Autowired
FakeSftpServer fakeSftpServer;

@Autowired
@Qualifier("toSftpChannel")
private MessageChannel toSftpChannel;

@After
public void setupRemoteFileServers() {
        this.fakeSftpServer.recursiveDelete(this.fakeSftpServer.getSourceLocalDirectory());
        this.fakeSftpServer.recursiveDelete(this.fakeSftpServer.getTargetSftpDirectory());
}

@Test
public void testSftpOutboundFlow() {
        boolean status = this.toSftpChannel.send(MessageBuilder.withPayload(new File(this.fakeSftpServer.getSourceLocalDirectory() + "\\" + "localSource1.txt")).build());

        RemoteFileTemplate<ChannelSftp.LsEntry> template = new RemoteFileTemplate<>(this.cachedSftpSessionFactory);
        ChannelSftp.LsEntry[] files = template.execute(session ->
                        session.list(this.fakeSftpServer.getTargetSftpDirectory() + "\\" + "localSource1.txt"));
        assertEquals(1, files.length);
        //assertEquals(3, files[0].getAttrs().getSize());
    }
}

现在，当我运行此测试时，出现以下异常：

我现在无法解决它并坚持了很长时间。 我是spring-integration-dsl的初学者，我们将非常感谢您的帮助。

引起原因：java.net.ConnectException：连接被拒绝：connect

您连接到错误的端口。

测试连接工厂在随机端口上侦听-您需要使用相同的端口。
