Java http入站网关中的错误通道未捕获来自消息转换器的消息传递异常

但是SeerealErrorHandler什么也抓不到。（没有来自CustomErrorHandler的日志）

似乎spring默认错误处理程序管理对用户的返回响应

如何在错误通道中捕获这些错误（来自消息转换器）

• 问题是，未捕获来自消息转换器的异常，而捕获SendChannel和ReplyChannel之间发生的其他异常。如何从消息转换器捕获异常

---

转换过程中过早出现错误；错误通道仅获取网关下游发生的错误

您可能可以使用servlet过滤器做一些事情

    public void handle(Message<?> message) {
    logger.debug("payload: {}", message.getPayload());
    }
}
