我一直在我的本地重新创建这个例子:https ://github.com/spring-projects/spring-integration-samples/tree/master/basic/sftp
但这次只使用注释而不是 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;
}
}
Sftp普通类:
@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;
}
}
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 是这个:
org.springframework.messaging.MessagingException: 获取池项失败;嵌套异常是 java.lang.IllegalStateException: failed to create SFTP Session at org.springframework.integration.util.SimplePool.getItem(SimplePool.java:178) at org.springframework.integration.file.remote.session.CachingSessionFactory.getSession( CachingSessionFactory.java:123) 在 com.spring.example.sftp.SftpOutboundTransferSample.testOutbound(SftpOutboundTransferSample.java:62) 在 sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) 在 sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java: 57) 在 sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) 在 java.lang.reflect.Method.invoke(Method.java:606) 在 org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.爪哇:
我已经在 Internet 上进行了搜索,但老实说,我不明白为什么会出现此异常:
com.jcraft.jsch.JSchException:数据包损坏
我的 log4j.xml 配置:
