網上搜尋了一下解決方案

1.說是springboot自動設定了支援mongodb。在啟動springboot時會自動執行個體化一個mongo執行個體。 要加上
@SpringBootApplication(exclude = MongoAutoConfiguration.class)，但是我的不行，原文連結如下。

2.說在設定檔裡把初始的 mongodb 取消掉就好了（不懂怎麼取消）

3.最後發現我用的idea，spring initializr選擇的依賴是testCompile的，在運行環境下沒有

 這是springboot預設的

 

testCompile(‘de.flapdoodle.embed:de.flapdoodle.embed.mongo‘)

打包成jar在Linux下運行報錯

 

改成

compile(‘de.flapdoodle.embed:de.flapdoodle.embed.mongo‘)

 正常運行
