我花了很多時間用這個！我的錯！我無法解決這個問題。這是我第一次使用Spring MVC進行Spring JPA練習。在tomcat上部署.ear文件時出現以下錯誤。在Spring數據中沒有發現依賴項的類型資源庫的合格bean JPA

項目結構： 
任何建議，我犯了錯誤，以及如何解決相同的問題。
另外這是我的第一個春季數據實踐項目，如果我在代碼或配置或項目結構中犯了錯誤，請將您的寶貴建議改正。
您的'@ Bean'方法應該是公共的，爲什麼要混合註釋和基於xml的配置？雖然你可能不意味着你應該... –
你有'entityManagerFactoryBean.setPackagesToScan（「com.cignex.repo」）;'在配置中。它不應該是'entityManagerFactoryBean.setPackagesToScan（「com.demo.model」）;'？ – user2953113
@ M.Deinum，我試着將我的Bean方法公開。我仍然面臨同樣的問題。你能幫我解決這個問題嗎？ – Vinod
