Java SpringIntegration2-Splitter只返回第一个元素

我使用的是SpringIntegration2。我有下面的场景。“MassMessageObject”由正文字段和收件人列表组成。我正在实现一个拆分器，为列表中的每个收件人创建一个“BasicMessageObject”。问题是拆分器的输出通道只接收第一条消息。例如：

MassMessageObject>[正文：你好，收件人{A，B}] 正在创建BasicMessageObject的列表 {[正文：你好，收件人：A]，[正文：你好，收件人：B]}

连接到输出通道的终结点正在接收“[body:Hello，收件人：A]”，而不是“[body:Hello，收件人：B]”

以下是我的应用程序上下文：

<int:splitter input-channel="mass_receiving_channel"
                  output-channel="receiving_channel"                  
                  method="splitMessages"
                  ref="massMessageSplitter"/>

<!-- Main Chain. The one that will lead to the messageTypeRouter -->
<int:chain input-channel="receiving_channel" output-channel="sms_channel">
        <int:service-activator ref="saveMessageToDB" method="saveMessageToDB"/>
        <int:gateway request-channel="message_type_router_channel"/>
</int:chain>

以下是拆分器

public List<BasicMessageObject> splitMessages(final GenericMessage message) {
        List<BasicMessageObject> messages = new ArrayList<BasicMessageObject>();
        // DOING STUFF HERE 
        return messages;
    }
}

我也有同样的问题。将任务执行器添加到拆分器的传出通道使Spring能够传递来自拆分器的所有消息：

<splitter input-channel="incoming-splitter" output-channel="outgoing-splitter"/>

<channel id="outgoing-splitter">
  <dispatcher task-executor="taskExecutor"/>
</channel>

<bean id="taskExecutor" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
  <!-- Use 1 for sequential processing -->
  <property name="corePoolSize" value="1"/>
  <property name="maxPoolSize" value="1"/>
  <property name="threadNamePrefix" value="Splitter Message Handler "/>
  <property name="waitForTasksToCompleteOnShutdown" value="true"/>

我建议您将org.springframework.integration的logger设置为DEBUG运行。您应该能够跟踪消息并找出发生了什么。如果没有，请在此处发布日志。使用此配置，在第一条消息完成之前，不会发送第二条消息。如果您希望它们在单独的线程上运行，则需要n异步切换。感谢您的回复Gary…有趣的是，我刚刚使用拆分器完成了一个小型POC，猜猜看是什么。它工作得很好。所以它一定是一些错误的conifg。我会采纳您的建议，增加日志记录以进行调试。干杯。我发现将输出通道连接到激活服务而不是一个链就可以做到这一点。另外，我在spring集成代码中进行了调试，发现了ou
