我有一个大的Spring Boot应用程序，其中使用了RabbitMQ等技术。 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。今天我升级到版本1.1.0，现在启动时出现异常。
问题似乎是HealthIndicator会检测到RabbitMQ可用，并尝试设置其健康指标。然后它无法注入rabbitTemplate并立即失败。错误消息的一部分是：“Error creating bean with name 'rabbitTemplate': Requested bean is currently in creation: Is there an unresolvable circular reference?”
下面是实际的异常跟踪。
