這兩天程序一直報錯，下面這個錯誤

經過兩天的反覆查找，終於發現自己犯了一個Spring bean配置混淆的錯誤。

上面配置@repository表示，TellersDao類已經作爲bean交給Spring來管理了，但是類又使用了

ctx=new ClassPathXmlApplicationContext("applicationContext.xml"); 方式來裝載bean，

這樣兩種方式就衝突了，所以會報那個錯誤。

所以，要麼用ctx=new ClassPathXmlApplicationContext("applicationContext.xml");的方式，如下圖

要麼用基於註解的方式
