Spring boot bootstrap.yml文件使用遇见的坑Failed to load property source from location 'classpath:/bootstrap.

异常信息如下:

解决办法
仔细的检查一下你的配置文件;我出现该错误的原因是因为如下代码:

eureka:  instance:    instance-id: ${spring.cloud.client.ipAddress}:${server.port} #实例信息，显示IP和端口eureka:  client:    serviceUrl:      defaultZone: http://springcloudserver-first:9090/eureka/,http://springcloudserver-two:9091/eureka/ # 指定注册中心的位置

貌似是不符合yml文件的书写规范,上边有一个eureka了,下边我又写了一个,删除掉下边的,就ok了,一个坑
