Spring集成，堆棧溢出錯誤

Question

你好，這是我的SI配置：

<!-- Inbound/Outbound Channels employeeSearchRequest--> 
    <int:channel id="accountRequest" /> 
    <int:channel id="accountResponse" /> 
    <int:channel id="catRequestChannel" /> 
    <int:channel id="mataccountRequest" /> 
    <int:channel id="errorChannel"/> 



    <int-http:inbound-gateway id="cwebAccountManagementGateway"  
     supported-methods="GET, POST" 
     request-channel="accountRequest" 
     reply-channel="accountResponse" 
     mapped-request-headers="*"  
     mapped-response-headers="*" 
     view-name="/policies" 

     path="/services/{class}/{method}" 
     reply-timeout="50000" 
error-channel="errorChannel"> 




     <int-http:header name="serviceClass" expression="#pathVariables.class"/> 
     <int-http:header name="serviceMethod" expression="#pathVariables.method"/> 

    </int-http:inbound-gateway> 


    <int:header-value-router input-channel="accountRequest" 
     header-name="state" 
     default-output-channel="accountRequest" resolution-required="false"> 
     <int:mapping value="MAT" 
      channel="mataccountRequest" /> 
      <int:mapping value="CAT" 
      channel="catRequestChannel" /> 

    </int:header-value-router> 

    <int:service-activator id="accountServiceActivator" 
       input-channel="mataccountRequest" 
       output-channel="accountResponse" 
       ref="serviceGatewayAdapter" 
       method="requestHandler" 
       send-timeout="60000"/> 

     <int:service-activator id="caRequestActivator" 
       input-channel="catRequestChannel" 
       output-channel="accountResponse" 
       ref="caServiceGatewayAdapter" 
       method="requestHandler" 
       send-timeout="60000"/> 

       <int:service-activator id="errorRequestActivator" 
       input-channel="errorChannel" 
       output-channel="accountResponse" 
       ref="errorGatewayAdapter" 
       method="errorHandler" 
       send-timeout="60000"/> 

當我把這個服務正在逐漸堆棧溢出exception.When我想在tomcat的這個項目中我得到這個STAK溢出異常當過我不要指定狀態參數作爲標題與CAT或MAT.But當我部署在Websphere服務器 即使通過狀態pareameter我得到堆棧溢出異常。請給一些解決方案.Follwing是整個堆棧跟蹤。我無法粘貼整個堆棧我正在粘貼堆棧跟蹤的一部分。

Answer 1

你<int:header-value-router/> couses問題：他的default-output-channel是一樣的input-channel。因此，如果路由器沒有通過映射解析該信道，則將該消息發送到其default-output-channel，但是這裏該信道是用於獲得該路由器的消息的信道。由於accountRequest是Dirrect通道，所有工作都在同一個線程完成。它會導致StackOverflowError。

只要改變default-output-channel任何其他適當途徑
