在import resource 路徑中有兩種寫法

一種classpath，一種classpath*

那么這兩種有什么區別呢？

1.**classpath:**只會到你的class路徑中查找找文件；

2.**calsspath*😗*不僅包含class路徑，還包括jar文件中(class路徑)進行查找，***classpath*😗**對于多module的項目比較重要

但往往我們導入一個新的項目設置好路徑后，還會報出Cannot resolve file 'applicationContext.xml’

運行localhost:8080時，會報出：

檢查一陣路徑，發現沒有任何問題。其實這個問題是一個幾乎可以認為是一個不應該迷惑著我們的問題，也正如當局者迷，最簡單的確實最讓我們犯錯誤的。

resources文件屬性是否設置了

點擊后：正確的樣子

這樣路徑就不會出錯了。
