我正在尝试使用 citrus 框架测试一个简单的 tcp 发送/接收序列。我可以很好地发送消息，但接收消息被证明是有问题的。基本上，柑橘不会检测到回复，然后柑橘会超时。

柑橘豆配置：

<?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:citrus="http://www.citrusframework.org/schema/config"
   xmlns:int="http://www.springframework.org/schema/integration"

    http://www.springframework.org/schema/integration/ip  http://www.springframework.org/schema/integration/ip/spring-integration-ip.xsd">

<citrus:channel-endpoint id="citrusServiceInputEndpoint"
                         channel-name="input" />

<citrus:channel-endpoint id="citrusServiceRepliesEndpoint"
                         channel-name="replies" />

<int-ip:tcp-connection-factory id="client"
                               type="client" host="localhost" port="9123" single-use="false"
                               so-timeout="10000" using-nio="true" />

<int:channel id="input" />

<int:channel id="replies">
    <int:queue capacity="10" />
</int:channel>

<int-ip:tcp-outbound-channel-adapter
        id="outboundClient" channel="input" connection-factory="client" />

<int-ip:tcp-inbound-channel-adapter
        id="inboundClient" channel="replies" connection-factory="client" />

柑橘测试用例：

@Test
@CitrusTest(name = "sendSpringIntegrationMessageTest")
public void sendSpringIntegrationMessageTest() throws Exception {
    send("citrusServiceInputEndpoint").payload("Req");
    receive("citrusServiceRepliesEndpoint").payload("Rsp");
}

我使用一个简单的 netcat 服务器进行测试：

nc -kl 9123

运行测试用例时，netcat 上的“Req”文本正常。但是，在 netcat 上键入“Rsp”时，数据未到达柑橘测试。大约 5 秒后，测试用例失败并显示以下消息：

所以基本上 Citrus 没有收到回应。请注意，我必须为回复通道定义一个队列，因为这是 Citrus 所期望的，回复通道必须实现接口 PollableChannel。

请帮助我理解为什么 Citrus 没有从队列中收到数据？

默认情况下，tcp 连接工厂期望消息由\r\n.

nc终止响应，以\n使连接工厂看不到完整的消息。

请参阅文档中有关 serializers/deserializers 的讨论。您需要配置serializeranddeserializer以指向一个ByteArrayLfSerializer只希望\n终止消息的 bean。

这是使该测试正常工作的正确 bean 配置。按照 Gary 的建议添加了序列化器/解串器。

我还必须添加一个消息转换器（object-to-string-transformer），因为 Spring 在回复通道上提供的数据将是 byte[] 类型。Citrus 期望针对 String 类型进行验证，因此需要进行转换才能将字节数组转换为字符串。

希望它会帮助将来的人！
