RabbitMQ 上的 Autoconfigure 的 Spring Boot 启动失败

我有一个大型 Spring 引导应用程序，其中使用了 RabbitMQ。我为 Rabbit 队列创建了一个 @Configuration 文件。这在 Spring boot 1.0.2 上运行良好。今天我升级了 1.1.0 版本，现在我在启动时遇到异常。

问题似乎是 HealthIndicator 发现 RabbitMQ 可用并尝试为其设置健康指示器。然后它立即失败，因为它无法注入(inject) rabbitTemplate。部分错误消息说，“创建名称为‘rabbitTemplate’的 bean 时出错:当前正在创建请求的 bean:是否存在无法解析的循环引用？”

下面包含实际的异常跟踪。

请您参考如下方法:

这看起来像是 Spring Boot 中新的健康指标的一个错误。我养了https://github.com/spring-projects/spring-boot/issues/1081 .

在修复之前，您可以通过在 application.properties 中设置 health.rabbit.enabled=false 为兔子禁用 HealthIndicatorAutoConfiguration。
