未注入的服務和存儲庫

Question

我對此完全絕望。這些是我在春季的第一天，我無法正常工作 - XMLProfileService根本沒有被注入，它仍然是空的。如果你能給我一些提示，我將非常感激。我在日誌中沒有錯誤。

Answer 1

創建Main2爲五言春天的new Main2()對它一無所知。 在春天的環境中創建它。將此添加到spring-config.xml中

<bean id="main2id" class="Main2"> 
</bean> 

然後找到它。在applicationContext上有一些方法可以通過id找到bean。你需要將結果投到你的課程Main2。並在之後調用您的run方法。
