作为 Citrus 测试的一部分,我想通过 SFTP 将 CSV 文件推送到服务器。使用 Spring Integration 似乎应该可以做到这一点。我尝试使用以下代码:

柑橘-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xmlns:int="http://www.springframework.org/schema/integration"
       xmlns:int-sftp="http://www.springframework.org/schema/integration/sftp"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

">

    <!-- Common settings -->
    <context:property-placeholder location="classpath:citrus.properties"/>

    <citrus:schema-repository id="schemaRepository"/>   

    <!-- SFTP component -->
    <bean id="sftpSessionFactory" class="org.springframework.integration.file.remote.session.CachingSessionFactory">
        <constructor-arg ref="defaultSftpSessionFactory" />
    </bean>

    <bean id="defaultSftpSessionFactory"
          class="org.springframework.integration.sftp.session.DefaultSftpSessionFactory">
        <property name="host" value="${sftp.host}"/>
        <property name="privateKey" value="${sftp.private.keyfile}"/>
        <property name="port" value="${sftp.port}"/>
        <property name="user" value="${sftp.username}"/>
        <property name="allowUnknownKeys" value="true"/>
    </bean>

    <int-sftp:outbound-channel-adapter id="sftpOutboundAdapter"
                                       session-factory="sftpSessionFactory"
                                       channel="inputChannel"
                                       remote-filename-generator-expression="payload.getName()"
                                       remote-directory="/tmp/citrus">
        <int-sftp:request-handler-advice-chain>
            <int:retry-advice />
        </int-sftp:request-handler-advice-chain>
    </int-sftp:outbound-channel-adapter>

    <int:channel id="inputChannel"/>

    <citrus:channel-endpoint id="sftpEndpoint" channel="inputChannel" />
</beans>

SftpTransferIT.java

public class SftpTransferIT extends TestNGCitrusTestDesigner {

    @Autowired
    ChannelEndpoint sftpEndpoint;

    @Test @Parameters("context")
    @CitrusTest(name = "SftpTransferIT.sendFileByFTP")
    public void sendFileByFTP(@Optional @CitrusResource TestContext context) {

        final File file = new File("C:\\Temp\\example.xml");
        final org.springframework.messaging.Message<File> message = MessageBuilder.withPayload(file).build();
        Message ftpMessage = new ChannelMessageConverter().convertInbound(message,sftpEndpoint.getEndpointConfiguration(),context);

        send(sftpEndpoint).message(ftpMessage);

    }
}

在这种情况下会引发以下异常:

Caused by: org.springframework.messaging.MessagingException: Failed to write to '/tmp/citrus/example.xml.writing' while uploading the file; nested exception is org.springframework.core.NestedIOException: failed to write file; nested exception is 2: No such file

    ... 70 more
Caused by: 2: No such file
    at com.jcraft.jsch.ChannelSftp.throwStatusError(ChannelSftp.java:2873)

我认为错误在于我如何通过 Citrus 发送消息。有人可以建议如何通过 Citrus 正确发送 org.springframework.messaging.Message 吗?

还是在没有 Citrus 的 send() 的情况下使用纯 Spring 集成来执行这样的任务是更好的做法?

尝试配置use-temporary-file-name = "false"

默认情况下,正在传输的每个文件都将出现在文件系统中,并带有一个附加后缀,默认情况下是 .writing;这可以使用临时文件后缀属性进行更改。

但是,在某些情况下您可能不想使用此技术(例如,如果服务器不允许重命名文件)。对于这种情况,您可以通过将 use-temporary-file-name 设置为 false(默认为 true)来禁用此功能。当此属性为 false 时,将使用其最终名称写入文件,并且消费应用程序将需要一些其他机制来检测文件是否已完全上传,然后再访问它。

并确保它/tmp/citrus确实存在于您的 SFTP 上。
