Usage

From source file:org.springframework.integration.ftp.inbound.FtpInboundRemoteFileSystemSynchronizerTests.java

@Test
public void testCopyFileToLocalDir() throws Exception {
    File localDirectoy = new File("test");
    assertFalse(localDirectoy.exists());

    TestFtpSessionFactory ftpSessionFactory = new TestFtpSessionFactory();
    ftpSessionFactory.setUsername("kermit");
    ftpSessionFactory.setPassword("frog");
    ftpSessionFactory.setHost("foo.com");
    FtpInboundFileSynchronizer synchronizer = spy(new FtpInboundFileSynchronizer(ftpSessionFactory));
    synchronizer.setDeleteRemoteFiles(true);
    synchronizer.setRemoteDirectory("remote-test-dir");
    synchronizer.setFilter(new FtpRegexPatternFileListFilter(".*\\.test$"));
    synchronizer.setIntegrationEvaluationContext(ExpressionUtils.createStandardEvaluationContext());

    ExpressionParser expressionParser = new SpelExpressionParser(new SpelParserConfiguration(true, true));
    Expression expression = expressionParser.parseExpression("#this.toUpperCase() + '.a'");
    synchronizer.setLocalFilenameGeneratorExpression(expression);

    FtpInboundFileSynchronizingMessageSource ms = new FtpInboundFileSynchronizingMessageSource(synchronizer);

    ms.setAutoCreateLocalDirectory(true);

    ms.setLocalDirectory(localDirectoy);
    ms.afterPropertiesSet();//from www  . j a  v a 2 s .c  o m
    Message<File> atestFile = ms.receive();
    assertNotNull(atestFile);
    assertEquals("A.TEST.a", atestFile.getPayload().getName());
    Message<File> btestFile = ms.receive();
    assertNotNull(btestFile);
    assertEquals("B.TEST.a", btestFile.getPayload().getName());
    Message<File> nothing = ms.receive();
    assertNull(nothing);

    // two times because on the third receive (above) the internal queue will be empty, so it will attempt
    verify(synchronizer, times(2)).synchronizeToLocalDirectory(localDirectoy);

    assertTrue(new File("test/A.TEST.a").exists());
    assertTrue(new File("test/B.TEST.a").exists());
