[英]Spring Integration gateway error channel - no such bean exception
I've configured a spring integration gateway with a service activator backed by a threadpool. 我已经配置了一个带有线程池支持的服务激活器的spring集成网关。 Everything works fine, till I try to add my own error channel.
一切正常,直到我尝试添加自己的错误通道。 Spring begins to complain that it cannot find a bean by the name of the error channel.
Spring开始抱怨它无法通过错误通道的名称找到一个bean。
Here is my xml config: 这是我的xml配置:
<int:gateway service-interface="Messaging.SendMessageToDeviceGateWay"
error-channel="send_message_to_device_error_channel"
default-request-channel="send_message_to_device_channel"
id="send_message_to_device_gateway">
</int:gateway>
<int:channel id="send_message_to_device_channel">
<int:queue message-store="redisMessageStore" />
</int:channel>
<bean id="sendMessageToDeviceServiceBeanId" class="Messaging.SendMessageToDeviceService" />
<int:service-activator input-channel="send_message_to_device_channel"
ref="sendMessageToDeviceServiceBeanId" method="send_message">
<int:poller fixed-rate="500" time-unit="MILLISECONDS"
task-executor="send_message_to_device_task_executor" receive-timeout="0" />
</int:service-activator>
<bean id="sendMessageToDeviceErrorHandlerBeanId"
class="Messaging.SendMessageToDeviceErrorHandler" />
<int:service-activator input-channel = "send_message_to_device_error_channel"
ref="sendMessageToDeviceErrorHandlerBeanId" method="handle_error">
</int:service-activator>
The error I am seeing is : 我看到的错误是:

Why is it looking for a bean by that name? 为什么要寻找那个名字的豆子?
Thanks in advance, Richard. 预先感谢,理查德。
That's correct: any bean must be presented in the application context. 没错:任何bean必须在应用程序上下文中显示。
Even if you use a default errorChannel
, it is populated to the application context by the Spring Integration infrastructure. 即使使用默认的
errorChannel
,Spring Integration基础结构errorChannel
其填充到应用程序上下文中。
So, you must provide <channel id="send_message_to_device_error_channel"/>
anyway. 因此,无论如何,您必须提供
<channel id="send_message_to_device_error_channel"/>
。
