我包這個錯不知道是啥問題
2017-08-15
這個問題我也存在 但是把所有類放到一個包下面就好了
2017-07-16
復制的時候 多了這個<scope>test</scope>在 pom中
2017-06-09
我跟你的錯誤一樣，但是用了import org.springframework.data.jpa.repository.JpaRepository;還是沒解決/(ㄒoㄒ)/~~還可能是什么原因嗎
2017-05-30
是的，是要注入GirlRepository，和GirlProperties沒關系，要不你對比下我的，我能執行?；蛘吣愕拇aidea有提示錯誤嗎？

黑體文字加了嗎？
回復你不能加黑體，你看這個回復 ?黑體部分

注意上面加粗的文字
