关于java中连接MongoDB延迟解决方案

在测试类中调用继承了MongoRepository接口的方法fildAll()，run后连接MongoDB数据库超时

application.yml中配置的连接信息也没毛病，用户是存在的

server:
  port: 31001
spring:
  application:
    name: xc‐service‐manage‐cms
  data:
    mongodb:
      uri: mongodb://root:[email protected]:27017
      databa

。。。原来是没有这个用户，用studio 3T重新创建了下，咳，低级错误
创建一个.

解决了，查到数据了
