我在嘗試在代碼中創建實體管理器時出現此錯誤。persistence.xml - 解析XML時出錯:XML InputStream(1)文件過早結束

EntityManagerFactory emf = Persistence.createEntityManagerFactory("puDS1", myproperties); 

任何提示爲什麼會發生這種情況?我的persistence.xml似乎是一個有效的XML。

持久性xml看起來像這樣。請注意,我在這個persistence.xml中使用了maven資源過濾,所以在編譯期間$ {jar_file_name_ds1}和$ {jar_file_name_ds2}被替換爲有效名稱。我已經驗證最終的persistence.xml中的值已被正確替換。我不知道如果maven資源過濾是搞砸了。

<?xml version="1.0" encoding="UTF-8"?>

     <properties>   
     <property name="hibernate.max_fetch_depth" value="3"/>

你可以發佈你的persistence.xml嗎? –

剛更新的問題與persistence.xml –

我會建議Maven資源過濾替換引入了一些無效的混淆XML解析器。你可以發佈替代的結果嗎?這應該在你的'target'目錄中可用。 –

問題是,代碼試圖連接到互聯網(我認爲得到xsd來驗證persistence.xml)。當我將機器連接到互聯網時,它開始工作。我試圖解決這個問題,所以我不需要連接到互聯網,但這是一個不同的問題。
