我在這裏確實需要幫助.. 我試圖創建simple webapps具有依賴關係的springboot：web，postgresql，jdbc，vaadin。 當開始運行我的應用程序時，應用程序將不會啓動並引發異常。 指示「..no類型爲JdbcTemplate的合格bean」的異常。 在stackoverflow的一些建議添加神器spring-boot-starter-jdbc，但我的POM已經做到了，仍然無法工作。通過字段'jdbcTemplate'表示的不滿意的依賴關係
下面我的配置
的src /主/資源/ application.properties：
spring.datasource.url=jdbc:postgresql://localhost:5432/sehati
spring.datasource.username=sehati
spring.datasource.password=password

，也是我一直嘗試使用H2數據庫。我的應用程序可以啓動，但似乎數據源連接始終使用來自spring-boot-jdbc（url='jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=false', username='sa'）的預配置數據源，即使我已經在application.properties中描述了新的應用程序。
有人能找到我的項目出了什麼問題嗎？ 非常感謝您的幫助。
有你沒有顯示的東西。我最好的猜測是你的系統中有兩個'DataSource'。 'application.properties'中的配置將確保爲您創建一個'DataSource' bean。難道你自己在創建數據源？使用「--debug」運行您的應用程序，您將得到一個報告，解釋爲什麼JdbcTemplateAutoConfiguration未啓用。 –
Hi @Stephane。謝謝你的線索。我只在application.properties和AFAIK中配置了一個數據源，但沒有創建其他數據源。我的完整的eclipse項目可以訪問[這裏]（https://www.dropbox.com/s/wgee2bgoc9hkrx8/siapotek.tar.gz?dl=0）。請審查我的項目。 – Midoen
我也嘗試調試項目，但我不知道在eclipse [控制檯]（https://www.dropbox.com/s/q0ztkqme89tzukv/console.out?dl=0）中拋出的異常。一個輸出線讓我好奇，它說「跳過（空）配置文件...」，我已經檢查了application.properties已經包含數據源config – Midoen
