无效的mongo配置，当spring boot mongodb uri通过application.yml文件提供时

Question

当我给localhost时，port可以正常工作，但不能使用uri属性工作。以下是获取错误。我将启用存储库属性设置为true

我正在使用mongorepositroy将对象保存到mogodb

Caused by: java.lang.IllegalStateException: Invalid mongo configuration, either uri or host/port/credentials must be specified

这是application.yml

spring:
  data:
    mongodb:
       uri: mongodb://server1:27017,server2:27017,server3:27017/dbname

使用以下pom.xml
