Spring集成。如何捕获自定义异常？

似乎我不了解Spring集成中自定义异常处理的一些基本概念(

我需要截获一些RuntimeException派生的自定义异常（从Java方法抛出），并根据其类型将应用程序执行流路由到其他路由

我使用的是Spring集成版本4.3.10.0

为此，我声明int:exception类型路由器如下：

<int:exception-type-router input-channel="errorChannel" default-output-channel="nullChannel">
        <int:mapping exception-type="com.surr.exception.SurrRoutingException"
                     channel="handleRedirectChannel"/>
        <int:mapping exception-type="com.surr.exception.SurrFatalException"
                     channel="surrChannelMain"/>
        <!-- some more mappings -->
</int:exception-type-router>

错误通道声明：

private final QueueChannel errorChannel;

@Autowired
public IntentsService(@Qualifier("errorChannel1") QueueChannel errorChannel) 
{
        this.errorChannel = errorChannel;
}

---

我认为您的困惑是因为

可以处理堆栈跟踪以跟踪预期的异常，但通道上的

数据类型是负载的确切类型

有关更多信息，请参阅文档：



我想说，你不需要一个
数据类型
用于
HandlerRedirectChannel
，因为你只从那个路由器上使用它。
数据类型
的目的实际上是限制这个通道的生产者，当我们的应用程序足够复杂时，这是有意义的，当我们无法控制生产者时，它甚至可以在分布式状态下工作。对于您的异常路由器来说，这看起来不像是一个案例…
我又回到了这个问题。还没有制作一个示例项目，但在文档中找到了一些信息。“SI错误处理”：“这里需要了解的最重要的一点是，基于消息传递的错误处理仅适用于在TaskExecutor中执行的Spring集成任务引发的异常。这不适用于在与发送方相同的线程中运行的处理程序引发的异常（例如，通过本节前面介绍的DirectChannel）“

也许这就是问题所在？我的应用程序逻辑被划分在不同的链和路由之间，可能其中一些不是在TaskExecutor中执行的，因此全局拦截不起作用？我假设每个应用程序只有一个全局范围的拦截器是不够的。我将验证这个假设。谢谢！
Yo你可以而且应该编辑你的问题，将你认为可能有助于他人回答问题的任何信息包括在内。如果你可以将评论中的信息移到你的问题中，那就更好了。在发送后，你可能会有一些错误，所以在你的问题中看到这一点会很好。事实上，没有。我在单元测试中运行了我的链，在测试结束时，我尝试重新分析d来自通道的消息。其他测试没有异常运行正常，但此测试失败：路由未发生Hi Artem！非常感谢您的建议。不幸的是，它没有帮助（看来拦截机制根本不起作用，或者不知怎么被破坏了。我将更新最初的帖子以反映我最近的更新。仍然不知道你的应用程序发生了什么。你有没有可能与我们共享一个简单的项目，让我们复制和使用它？这样我们就可以调试你的流程，看看有什么问题。）继续。很难保证。事实上，我正在开发企业应用程序，当然不能分享。准备类似的项目样本需要一些时间，现在我因为这个问题超出了项目时间限制(（.也许您知道一些调试/诊断提示，有助于找出直接发送到“errorChannel1”的消息丢失的确切位置和原因？感谢您的帮助您可以打开
org.springframework.integration
类别的调试日志记录级别，查看消息在流中的传播方式。您可以在
Er中设置断点rorMessageExceptionTypeRouter.getChannelKeys（）
查看您的邮件发生了什么。您的日志中可能已经有一些堆栈跟踪，您没有与我们共享以获取更多信息。您在配置和解释中显示的内容必须正常工作。我们缺少一些您没有与我们共享的详细信息。可能您在该
errorChannel1
上有更多的消费者，因此您的邮件在那里旅行-不是到这个路由器。等等。你混合了太多的东西和一点旁道。如果你能提供一个简单的项目来玩就太好了。但正如你所解释的，它确实会失败。也许随着婴儿步骤的复制，你会在你的项目中看到一些你目前没有与我们分享的东西
