在RabbitMQ侦听器中隐藏运行时异常

在某些情况下，我使用了一些例外情况来拒绝该消息，但是在控制台中却显示了例外情况，乍一看似乎并不正确。

如何从控制台/文件登录中隐藏该特定异常

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");
    }
}

这里是列表器

@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");
}

这是我要隐藏的日志！在某些情况下必须重新排队该消息！

回答：

在您的日志记录配置中，为

org.springframework.amqp.rabbit.listener.ConditionalRejectingErrorHandler

到ERROR（该消息记录在WARN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）文件中。

如果您希望执行其他操作（例如记录某些异常），则可以制作的副本ConditionalRejectingErrorHandler并更改handleError()方法。该代码是在这里。

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）。
