解決方案：

• 報錯解決之前，MongoDB 數據庫連接配置

• spring:
    data:
      mongodb:
         host: 127.0.0.1 #mongoDB地址 port: 8888 #當前mongoDB的端口號 database: javaAnalysisWord #當前數據庫的名稱 username: xiaoming #當前數據庫的用戶名 password: 123456 #當前數據庫的用戶密碼

• 報錯解決之后，MongoDB 數據庫連接配置

• spring:
    data:
      mongodb:
         uri: mongodb://xiaoming:123456@localhost:8888/javaAnalysisWord

• 全配置

• spring:
    data:
      mongodb:
         uri: mongodb://xiaoming:123456@localhost:8888/javaAnalysisWord
   # 需要用戶名和密碼認證 #uri: mongodb://username:password@ip:port/admin  #不需要用戶名和密碼認證 #uri: mongodb://ip:port/admin
