我使用Spring Integration处理服务器和客户端之间的自定义TCP协议。这是我的context.xml:
<int-ip:tcp-connection-factory id="serverConnectionFactory"
type="server"
host=""
port="5678"
so-linger="5000"
so-keep-alive="true"
single-use="false"
using-nio="true"
so-timeout="5000"
serializer="customeMessageSerializerDeserializer"
deserializer="customeMessageSerializerDeserializer"/>
<int-ip:tcp-inbound-channel-adapter id="inAdapter.server"
channel="toSA"
connection-factory="serverConnectionFactory"/>
<int:channel id="toSA" datatype="com.my.Message"/>
<int:service-activator input-channel="toSA"
output-channel="toObAdapter"
ref="handleMessage"
method="handle"/>
<int:channel id="toObAdapter"/>
<int-ip:tcp-outbound-channel-adapter id="outAdapter.server"
channel="toObAdapter"
connection-factory="serverConnectionFactory"/>
<bean id="handleMessage" class="com.my.MessageHandler"/>
<bean id="customeMessageSerializerDeserializer"
class="com.my.MessageSerializyerDeserializer"/>
当我通过tomcat部署它时,它的服务时间只有几分钟,并且对客户端没有响应。发现一个错误:

我想知道如何修复它以及错误之处。
最佳答案
使用collaborating channel adapters时,必须确保在出站消息中设置ip_connectionId
标头,以便适配器知道将其写入哪个套接字。
通常,使用这样的简单流程,框架将负责将标头从入站消息传播到出站消息。
因此,我需要查看该方法以了解您的工作。
您的“ handleMessage”代码是什么样的?
另一种可能性是5秒超时-如果您的服务花费的时间超过了连接将不再存在的时间。
通常,打开DEBUG日志记录应有助于调试此类问题。
