我一直在重建我的本地这个例子:https://github.com/spring-projects/spring-integration-samples/tree/master/basic/sftp春JUnit测试:com.jcraft.jsch.JSchException:包腐败

但这次仅仅使用注解,而不是XML配置。我有这样的事情:

@Configuration 
public class SftpExampleBeanClasses extends SftpConfig { 

@Bean 
public CachingSessionFactory<LsEntry> sftpSessionFactory() throws IOException { 
    DefaultSftpSessionFactory sftpSessionFactory = new DefaultSftpSessionFactory(); 
    sftpSessionFactory.setHost(this.host); 
    sftpSessionFactory.setPort(this.port); 
    sftpSessionFactory.setUser(this.username); 
    InputStream stream = new ClassPathResource(this.privatekey).getInputStream(); 
    sftpSessionFactory.setPrivateKey(new ByteArrayResource(StreamUtils.copyToByteArray(stream))); 
    sftpSessionFactory.setPrivateKeyPassphrase(this.passphrase); 
    sftpSessionFactory.setAllowUnknownKeys(true); 
    return new CachingSessionFactory<LsEntry>(sftpSessionFactory); 

    //return sftpSessionFactory; 
} 

@SuppressWarnings({ "unchecked", "rawtypes" }) 
@Bean 
@ServiceActivator(inputChannel = "ftpChannel", adviceChain = "retryAdvice") 
public MessageHandler ftpHandler() throws IOException { 
    FileTransferringMessageHandler handler = new FileTransferringMessageHandler(this.sftpSessionFactory()); 
    handler.setRemoteDirectoryExpression(new LiteralExpression("/")); 
    return handler; 
} 

} 

SftpCommon类:

@Configuration 
public class SftpCommon extends SftpConfig { 

    @Bean 
    public int serverPort(){ 
     if(this.port == -1){ 
      return EmbeddedSftpServer.PORT; 
     } 
     return this.port; 
    } 

    @Bean 
    public EmbeddedSftpServer embeddedSftpServer(){ 
     EmbeddedSftpServer embeddedSftpServer = new EmbeddedSftpServer(); 
     embeddedSftpServer.setPort(serverPort()); 
     return embeddedSftpServer; 
    } 
} 

SftpConfig类:

@Configuration 
@PropertySource(value="classpath:user.properties") 
public class SftpConfig { 

    @Value("${port}") 
    protected 
    int port; 

    @Value("${username}") 
    protected 
    String username; 

    @Value("${passphrase}") 
    protected 
    String passphrase; 

    @Value("${host}") 
    protected 
    String host; 

    @Value("${private.keyfile}") 
    protected 
    String privatekey; 

    public String getHost() { 
     return host; 
    } 

    @Bean 
    public String getUsername() { 
     return this.username; 
    } 

    @Bean 
    public String getPassphrase() { 
     return this.passphrase; 
    } 

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

    @Bean 
    public String getPrivatekey() { 
     return privatekey; 
    } 
} 

而在我的测试中,我有这样的事情:

@RunWith(SpringJUnit4ClassRunner.class) 
    @ContextConfiguration(classes ={SftpExampleBeanClasses.class,SftpCommon.class, SftpConfig.class}) 
    public class SftpOutboundTransferSample { 

    @Autowired 
    ApplicationContext applicationContext; 

    @Test 
    public void testOutbound() throws Exception{ 

     final String sourceFileName = "README.md"; 
     final String destinationFileName = sourceFileName +"_foo"; 

     @SuppressWarnings("unchecked") 
     SessionFactory<LsEntry> sessionFactory = (SessionFactory<LsEntry>) 


     applicationContext.getBean(CachingSessionFactory.class); 
     /* this is the line where I'm getting issues */ 
     sessionFactory.getSession(); 
    } 

我的stackTrace是这样的:

我一直在寻找在互联网上,但说实话,我不为什么已了解我得到这个异常:

解决我的问题:

在我的* .properties文件服务器的端口号为-1。然后服务器尝试启动,如果它能够找到非-1的端口(随机端口),则它会自动启动。然后我必须在我的SFTP会话中注入该随机端口号。重点是,我在我的sftp会话中使用了“-1”值(在我的* .properties文件中声明),而不是使用服务器生成的随机值。然后我的会话无法连接到服务器。要考虑

点:

  • 在这种情况下,不幸的是, “调试” 级别jsch是没有用的。
  • 堆栈跟踪是“提示”,因为不知何故,如果你无法连接,那么,这可能意味着你正在使用错误的参数来连接(也许)。因此,至少在我的情况下,我在会话中使用了错误的端口号。
