配置Spring引導與H2數據庫

我配置與H2數據庫春季啓動應用程序，當我運行我的應用程序時結構上，我得到這個異常配置Spring引導與H2數據庫

問題iss不在你的pom文件中：'引起：org.springframework.data.mapping.PropertyReferenceException：沒有找到類型爲Booking的屬性findbyBookingName'' – Jens

這是我的BootApplication.java文件，請解釋一下請問什麼是問題。 –

看起來像您的實體中的映射問題 – Jens

在你JpaRepositoryCustom您有一個名爲findbyBookingName方法。但是，爲了遵守Spring Datas命名約定，它應該是findByBookingName（注意By的大寫字母B）。

我重視我的BootApplication .Java.Here我們得到一個異常::: org.springframework.beans.factory.BeanCreationException：從異常日誌 –

中看到名稱爲'jpaRepositoryCustom'的bean創建時出錯是的，我的回答仍然有效。 – dunni

它無法解決問題。該代碼仍會拋出相同的異常。 –
