Error handling Spring集成错误通道JUnit中无消息
我有一个简单的JUnit测试，通过连接Error handling Spring集成错误通道JUnit中无消息,error-handling,junit4,spring-integration,spring-junit,Error Handling,Junit4,Spring Integration,Spring Junit,我有一个简单的JUnit测试，通过连接服务激活器来测试errorChannel。然而，这个频道什么也没有 配置如下： <int:channel id="in"/> <int:service-activator id="inSA" input-channel="in" ref="thrower" output-channel="nullChannel"/> <bean id="thrower" class="com.att.dat
服务激活器来测试errorChannel
。然而，这个频道什么也没有
配置如下：
<int:channel id="in"/>
<int:service-activator id="inSA" input-channel="in" ref="thrower"
output-channel="nullChannel"/>
<bean id="thrower"
class="com.att.datalake.ifr.loader.exceptions.handler.Thrower" />
<int:service-activator input-channel="errorChannel" ref="errorManager"
id="errorMgr" method="handleMessage" />
<bean id="errorManager"
class="com.att.datalake.ifr.loader.exceptions.handlers.ErrorManager"/>
只有当下游流在单独的线程
内时，才会将带有异常的错误消息
抛出到错误通道
。否则，异常将被重新调用。不管怎样，它都会被抛出到调用方，但是如果Spring Integration没有原始调用方控件，它会被转移到错误通道
请参阅此处的更多信息：好的，谢谢，这很有意义。我将上游通道设置为队列通道，现在抛出的异常将进入errorChannel。多谢。
