我正在尝试通过Citrus-Framework发送和接收TCP消息，在这里我将此线程用作参考：
Receiving messages from tcp server with Citrus framework and Spring Integration times out
我正在使用python消息转发器，它返回接收到的消息。我通过python收到了一个有效负载，并将其返回，但柑橘类超时。我尝试了所有序列化程序（SingleTerminatior除外，会导致上下文错误）。
我尝试了不同的序列化器，但似乎都无法解决我的问题，Citrus总是超时。

这是citrus的调试输出：
Base64.Encoder encoder = Base64.getEncoder();
Base64.Decoder decoder = Base64.getDecoder();
byte[] bigIntegerBytes = BigInteger.valueOf(4294967295l).toByteArray();
String base64EncodedBigIntegerBytes = encoder.encodeToString(bigIntegerBytes);
System.out.println(base64EncodedBigIntegerBytes);
byte[] decodedBigIntegerBytes = decoder.decode(base64EncodedBigIntegerBytes);
BigInteger decodedBigInteger = new BigInteger(decodedBigIntegerBytes);
System.out.println(decodedBigInteger);
我检查了Wireshark，并返回了包含换行符的有效负载（“ Req”），可以在屏幕截图中看到。也许我应该提到我正在Ubuntu VM中运行它。

好的，我的python服务器似乎有问题。我稍稍更改了代码以查看控制台上收到的字节（之前我只是在计算字节数），然后突然改变了柑橘的输出。
@CitrusTest(name = "sendSpringIntegrationMessageTest")
public void sendSpringIntegrationMessageTest() throws Exception {
send("citrusServiceInputEndpoint").payload("Req");
receive("citrusServiceRepliesEndpoint").payload("Req");
}
EDIT2
由于以下帖子： How to use Spring Integration 5 with Spring Boot 1.5.x 我从spring-integration-ip 5.0.8切换到4.3.9，然后输出又改变了一次。现在，我的问题似乎已经从TCP问题转移到了实际的Spring专有技术上。
