java - 是否可以使用 DSL 将 bean id 分配给 spring 集成入站适配器

Question

使用 SI XML 分配 id 很简单，如下所示

<int-ftp:inbound-channel-adapter id="ftpInbound"
        channel="ftpChannel" session-factory="ftpClientFactory"
        filename-pattern="*.txt" auto-create-local-directory="true"
        delete-remote-files="false" remote-directory="${remotedir}"
        local-directory="/apps/wfg/ftp/test" auto-startup="true">
        <int:poller fixed-rate="1000">
            <int:transactional synchronization-factory="syncFactory" />
        </int:poller>
    </int-ftp:inbound-channel-adapter>

下面的 dsl 代码也可以做同样的事情吗？

IntegrationFlow flow = IntegrationFlows
        .from(Ftp
            .inboundAdapter(csf)
            .preserveTimestamp(true)
            .remoteDirectory(feed.getRemoteDirectory())
            .regexFilter(feed.getRegexFilter())
            .deleteRemoteFiles(feed.getDeleteRemoteFiles())
            .autoCreateLocalDirectory(
                feed.getAutoCreateLocalDirectory())
            .localFilenameExpression(
                feed.getLocalFilenameExpression()).get();

在这种情况下也可以完成相同的过渡同步。

Answer 1

IntegrationFlow flow = IntegrationFlows.from(Ftp.inboundAdapter(sessionFactory())
                .preserveTimestamp(true)
                .remoteDirectory("ftpSource")
                .regexFilter(".*\\.txt$")
                .localFilename(f -> f.toUpperCase() + ".a")
                .localDirectory(getTargetLocalDirectory()),
        e -> e.id("ftpInboundAdapter")
              .poller(Pollers.fixedDelay(100)
                    .transactionSynchronizationFactory(syncFactory())))
        .channel(out)
        .get();
