Spring引导启动失败，在RabbitMQ上自动配置

Question

我有一个大的Spring引导应用程序，其中包括RabbitMQ。我为Rabbit队列创建了一个@Configuration文件。这一直在Spring引导1.0.2正常工作。今天我升级了版本1.1.0，现在我在启动时遇到了异常。

问题似乎是，HealthIndicator发现RabbitMQ可用并尝试为其设置健康指示符。然后它会立即失败，因为它无法注入rabbitTemplate。部分错误消息说"Error creating bean with name 'rabbitTemplate': Requested bean is currently in creation: Is there an unresolvable circular reference?"

实际异常跟踪包括在下面。

这看起来像Spring Boot中新的健康指标的错误。我已经提出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来禁用HealthIndicatorAutoConfiguration。
