在某些故意发生的情况下，我使用了一些异常来拒绝消息，但在控制台中显示了乍一看似乎不太正常的异常。
如何在登录控制台/文件时隐藏该特定异常
我正在使用 spring-boot 和默认记录器！
public static class UndispatchException extends
AmqpRejectAndDontRequeueException{
public UndispatchException() {
super("Dispatch still looking for a driver");
}
}
这里是听者
@RabbitListener(queues = TEST_QUEUE)
public void handle(Dispatch in) {
if(in.isRequeue()){
log.debug("will reject the message");
throw new UndispatchException();
}
log.debug("won't reject the message");
}
这是我想隐藏它的日志！在某些情况下必须重新排队消息！

在日志记录配置中，设置日志级别
org.springframework.amqp.rabbit.listener.ConditionalRejectingErrorHandler
错误（该消息记录在警告级别）。
使用 Spring Boot，您只需添加...
logging.level.org.springframework.amqp.rabbit.listener.ConditionalRejectingErrorHandler=ERROR
...到您的 application.properties （或 .yml）文件。
EDIT
如果您希望做一些不同的事情（例如记录某些异常），您可以复制ConditionalRejectingErrorHandler并进行更改handleError()方法。这代码在这里 https://github.com/spring-projects/spring-amqp/blob/master/spring-rabbit/src/main/java/org/springframework/amqp/rabbit/listener/ConditionalRejectingErrorHandler.java#L74.
然后，您可以使用自定义错误处理程序配置侦听器容器（或侦听器容器工厂）。
