Document

This particular FTP implementation is based on the FTPClient#getStatus(String) by default, but since not all FTP servers properly implement the STAT command, the framework internal FtpRemoteFileTemplate instances are switched to the FTPClient#listNames(String) for only files operations.

Usage

From source file:org.springframework.integration.ftp.outbound.FtpServerOutboundTests.java

@Test
public void testInt3412FileMode() {
    FtpRemoteFileTemplate template = new FtpRemoteFileTemplate(ftpSessionFactory);
    assertFalse(template.exists("ftpTarget/appending.txt"));
    Message<String> m = MessageBuilder.withPayload("foo").setHeader(FileHeaders.FILENAME, "appending.txt")
            .build();//from  w w w.j a v  a2 s. c o m
    appending.send(m);
    appending.send(m);

    assertLength6(template);

    ignoring.send(m);
    assertLength6(template);
    try {
        failing.send(m);
        fail("Expected exception");
    } catch (MessagingException e) {
        assertThat(e.getCause().getCause().getMessage(), containsString("The destination file already exists"));
    }
