通過Toggle 'Skip Tests' Mode跳過測試解決數據庫插入兩條數據的問題

前段時間在做一個Maven項目的小功能時，需要將數據存儲進數據庫，但是卻遇到了插入一條記錄，執行成功后，數據庫卻存入兩條數據的情況。並且每次執行都會輸出如下的信息：

經過多次測試檢查后，發現通過IntelliJ IDEA找到Maven Projects面板，頂部有一個Toggle 'Skip Tests' Mode 圖標（命令行方式：mvn clean package -Dmaven.test.skip=true），選中它后再執行package或者install打包就會跳過測試。

最后再去執行自己的業務代碼，插入成功且只有一條記錄！后續對該功能問題有更好的理解再回來補充吧。
