我在使用JAXB2從XSD創建Java類時遇到了一個問題。使用帶有多級導入失敗JAXB的XSD到Java
請讓我知道，如果JAXB可以處理這個。
場景：
1）項目A有a.xsd和b.xsd用不同的名稱空間 b.xsd使用a.xsd與導入名稱空間標籤。
2）項目B具有c.xsd並通過導入b.xsd使用b.xsd。
c.xsd正在使用目錄在Maven JAR中查找作爲依賴項添加的b.xsd。
ISSUE：
項目A建立罰款，但項目B拋出錯誤，因爲它找不到a.xsd在內部使用b.xsd。

我不能看到'HTTP目錄條目：// www.example.com/address'。它可能試圖從_b.xsd_中指定的位置加載它，該位置是「http：// www.example.com/address/address.xsd」。 – teppic
謝謝@teppic。其實我之前沒有碰到過，我也這麼想過。基本上當我建立projecA有一個和B xsd，建立良好，問題出現在項目中有c xsd - >引用b xsd - >引用xsd。 a和b是作爲依賴關係提供的，可能是它在解析時無法從「c」級獲得「a」，但不確定是否有任何特定的方法來告知系統或目錄中的數據... – Dave
