Question

我正在尝试创建一个分布式日志记录系统，我的每个tomcat实例都会将日志放入交换/队列，它将被累积并存储在一个plcae中。我正在使用rabbitmq阅读有关Log4j + Amqp的信息。

我也下载了以下示例代码。 https://nodeload.github.com/SpringSource/spring-amqp-samples/zipball/master

从包中导入项目log4j。

当我运行IntegrationTest.java（Junit）时。我失败了。以下是追踪。

这种情况正在发生，因为观察时间内没有日志传入监听器AmqpLogMessageListener。

我对代码有些怀疑：

如何注册监听器AmqpLogMessageListener.java以侦听已配置的交换。
为什么测试失败？

Juste确定，请根据来源https://github.com/SpringSource/spring-amqp-samples/blob/master/log4j/src/main/resources/log4j.properties检查您的log4j属性文件。

然后，它可能是你在RabbitMQ上的连接可能很长，所以改变这个：新的CountDownLatch（1）;

由此：

new CountDownLatch（5）;

Log4j + Amqp日志示例代码失败
