我已经配置了一个Spring集成网关,其中包含一个由线程池支持的服务激活器。 一切正常,直到我尝试添加自己的错误频道。 Spring开始抱怨它无法通过错误通道的名称找到bean。
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>
我看到的错误是:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'send_message_to_device_gateway': Cannot resolve reference to bean 'send_message_to_device_error_channel' while setting bean property 'errorChannel'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'send_message_to_device_error_channel' is defined

为什么要用这个名字来寻找一个bean?
提前致谢, 理查德。
答案 0 :(得分:0)
这是正确的:任何bean都必须在应用程序上下文中显示。
即使您使用默认的errorChannel
,它也会被Spring Integration基础结构填充到应用程序上下文中。
因此,无论如何,您必须提供<channel id="send_message_to_device_error_channel"/>
。
