我目前嘗試按照教程，但有點問題，我添加一些內存持久性與h2的應用程序。我在Spring Boot中發現了一些有關h2自動配置的評論，他說，唯一要做的就是將依賴關係添加到pom中。是否有任何進一步的配置，我必須手動進行？ 我得到以下異常：h2數據庫彈簧啓動

看起來沒問題，也許運行'mvn clean install'？同時刪除顯式的'hibernate-core'和'hibernate-entitymanager'依賴項。使用'spring-boot-starter-data-jpa'時不需要它們。 – Strelok
感謝您的回答！我試圖做到這一點，但也得到與mvn乾淨安裝錯誤。我在'UPDATE'下張貼了一部分控制檯輸出（我不得不縮短它，因爲它的字符多於允許的字符） – manban
相同的教程可以運行在較老版本的spring引導上，比如說1.3.8。我在1.4.4和1.5.1中遇到了類似的問題。 –
