ファイルをリモート SFTP サーバーに送信しようとしています。同じ工場と outboundFlow を作成しました。
UploaderSftpConnectionFactoryBuilder
@Configuration

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

ここで、統合テストを使用してアウトバウンド フローをテストしたいと考えています。そのために、testContextの下に作成しました：
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();
}
}
@ https://github.com/spring-projects/spring-integration-java-dsl/blob/master/src/test/java/org/springframework/integration/dsl/testで提案されているように、偽の sftp サーバーも作成しました。 /sftp/TestSftpServer.java 以下は私の偽のサーバーです。
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();
}
}
}
最後に、以下は私のテストクラスです
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());
}
}
このテストを実行すると、以下の例外が発生します。

私はそれを解決することができず、かなり長い間それに固執しています。私は spring-integration-dsl の初心者であり、どんな助けも本当に感謝しています。
