Hibernate：無法解析配置：hibernate.cfg.xml？

我正在嘗試使用Hibernate withing我的應用程序時出現以下錯誤：Hibernate：無法解析配置：hibernate.cfg.xml？

org.hibernate.HibernateException: Could not parse configuration: hibernate.cfg.xml

是什麼原因造成的？請參閱下面的hibernate.cfg.xml,output和Runner class？

注意：我已經看過this answer，並嘗試使用建議修復它，但沒有運氣。

hibernate.cfg.xml中：

<?xml version='1.0' encoding='utf-8'?> 
    <!DOCTYPE hibernate-configuration PUBLIC 
      "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
      "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> 

    <hibernate-configuration> 
     <session-factory> 

      <!-- Database connection settings --> 
      <property name="connection.driver_class">com.mysql.jdbc.Driver</property> 
      <property name="connection.url">jdbc:mysql://localhost:3306/test-db</property> 
      <property name="connection.username">user</property> 
      <property name="connection.password">password</property> 

      <!-- SQL dialect --> 
      <property name="dialect">org.hibernate.dialect.MySQLDialect</property> 

      <!-- Echo all executed SQL to stdout --> 
      <property name="show_sql">true</property> 

      <!-- Use XML-based mapping metadata --> 
      <!-- <mapping resource="domain/Message.hbm.xml"/> --> 

      <!-- Use Annotation-based mapping metadata --> 
      <mapping class="entity.Message"/>    

     </session-factory> 
    </hibernate-configuration>

輸出：

你可以檢查下面我用過的CFG文件，並確保CFG文件將出現在SRC目錄下。如果您保留在另一個目錄中，請確保在獲取配置實例的同時傳遞路徑。

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE hibernate-configuration PUBLIC 
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> 
<hibernate-configuration> 
    <session-factory> 
     <property name="hibernate.connection.driver_class"> com.mysql.jdbc.Driver </property> 
     <property name="hibernate.connection.url"> jdbc:mysql://localhost:3306/hibernatex </property> 
     <property name="hibernate.connection.username"> root </property> 
     <property name="hibernate.connection.password"> root </property> 
     <property name="hibernate.dialect"> org.hibernate.dialect.MySQLDialect </property> 
     <mapping resource="com/ora/hibernate/examples/Employee.hbm.xml" 
      package="com.ora.hibernate.examples" /> 
    </session-factory> 
</hibernate-configuration>

謝謝，我找到了答案，那是我的資源目錄下沒有CFG文件 – java123999

爲了被解析爲XML，把hibernate.cfg.xml應該這樣開始：

<?xml version="1.0" encoding="utf-8"?> 
<!DOCTYPE hibernate-configuration PUBLIC 
"-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

檢查以下事情在hibernate.cfg.xml：

檢查是否有以前<?xml ?>
檢查是否有在hibernate.cfg.xml另一個<?xml ?>定義
檢查，如果存在<?xml ?>（http://www.w3.org/International/questions/qa-byte-order-mark#remove）之前字節順序標記（BOM）

對不起，我貼錯了，我也有類似這樣的東西。請參閱我的編輯 – java123999

嘗試我張貼的片段。 – user987339

我做了，我得到完全相同的錯誤信息？ – java123999

蹊蹺的配置的第二行文件。嘗試更改DTD文件的位置，如下所示。

<?xml version="1.0" encoding="utf-8"?> 
<!DOCTYPE hibernate-configuration SYSTEM 
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

More Info

希望這有助於。

嗨，我試過這個，但沒有運氣。不幸的是出現了相同的錯誤 – java123999

刪除'<？xml'標記之前的所有空格和新行，並在構建之前清理您的項目。 –

謝謝，如何在Intelij中清理項目？ – java123999

我能解決問題所在。問題是我的hibernate.cfg.xml文件不在我的項目內的「資源」目錄下。

這解決了我所遇到的所有問題，並且我做了而不是需要更改文件內的代碼。

這是因爲您的互聯網阻止從該DTD獲取數據。只是dowbload所有DTD是提xml文件中，並在所有的XML文件給位置這樣的.. 這對我的作品

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "C:\Downloads\hibernate-mapping-3.0.dtd"> <hibernate-configuration>
