Mongo DB规范地址与服务器地址不匹配

Question

我正在将我的spring boot应用程序与mongo db连接。

该代码在本地环境中运行良好，其中数据库只有一个节点，并且没有以集群模式运行。

但是，当db在具有群集模式和单个节点以及1个副本集的临时环境上运行时，spring应用程序会显示以下错误：

在这两种情况下，应用程序属性都是相同的，只是临时服务器的IP替换了本地主机：

spring.elasticsearch.education.hostname=localhost   // staging server IP
spring.elasticsearch.education.scheme=http
spring.elasticsearch.education.port=9200


###### Mongo properties ########
spring.data.mongodb.host=localhost  //staging server ip
spring.data.mongodb.port=27017
spring.data.mongodb.database=ddddd
spring.data.mongodb.authentication-database=admin
spring.data.mongodb.username=root
spring.data.mongodb.password=root
spring.data.mongodb.repositories.enabled=true
logging.level.org.springframework.data.mongodb.core.MongoTemplate=DEBUG

我检查了这个问题，但没有多少解决方案。

请告诉我这里出了什么问题？

看这里https://stackoverflow.com/a/34373673/5712629.

也许spring.data.mongodb.host和spring.data.mongodb.port不支持在这个版本的mongoDB驱动程序。

你可以试试：

spring.data.mongodb.uri=mongodb://root:root@localhost:27017
