我的RabbitMQ列表器失败了。 我使用Spring Boot 1.4.1和Spring集成4.3.3（使用spring-boot-starter-amqp和spring-integration-amqp）。我也使用RabbitMQ 3.5.7。
对于少量消息，在大量流量下随机发生问题（非运气再现在本地处理）。
让我感到困惑的是，堆栈跟踪并不指向我的应用程序，仅指向框架。下面我附上完整的堆栈跟踪。是spring，rabbitMQ驱动程序还是服务器的错误？

答案 0 :(得分：1)
经过长时间的调查后发现Spring或rabbitMQ没有任何问题。根本原因在我自己的代码中。
附加到问题的日志具有完整的堆栈跟踪，但是java会截断stacktraces！
Java 1.5.0引入了标志OmitStackTraceInFastThrow，默认启用。这是性能优化。它从异常中删除了栈跟踪的常见部分。
在我的情况下，我对此异常的前130次出现了完整的堆栈跟踪。进一步发生的堆栈跟踪被截断。获得完整堆栈跟踪的最简单方法是重新启动应用程序。
