這個類代表了一個應該從classpath中獲取的資源。 這使用線程上下文類加載器，給定的類加載器或給定的類來加載資源。
如果類路徑資源駐留在文件系統中，則該資源實現支持解析為`java.io.File`，但對于駐留在jar中并且尚未擴展的類路徑資源（通過servlet引擎或任何環境）不支持解析為 文件系統。 為了解決這個問題，各種資源實現總是支持解析為`java.net.URL`。
`ClassPathResource `是通過java構造方法顯示的創建的.但更多的是通過調用api方法隱式的創建,通過字符串參數的前綴來創建不同的`Resource `,如果沒有指定前綴,則任務是標準的URL,將創建`UrlResource`.
