錯誤在myeclipse中創建SessionFactory Hibernate反向工程數據庫

我在myeclipse中學習hibernate。我試圖逆向工程一個MySQL表，並遵循官方myeclipse教程。所有的XML文件生成，但寫一個簡單的測試程序，它給了我以下錯誤：錯誤在myeclipse中創建SessionFactory Hibernate反向工程數據庫

Exception in thread "main" java.lang.NullPointerException 
    at sor.hibernate.HitestTest.main(HitestTest.java:15)

測試程序是

package sor.hibernate; 


import java.util.Date; 

import org.hibernate.Session; 
import org.hibernate.Transaction; 


public class HitestTest { 

    public static void main(String[] args) { 

     HitestDAO dao = new HitestDAO(); 
     Transaction tx = dao.getSession().beginTransaction(); 

     Hitest hitest[] = new Hitest[10]; 
     for (int i = 0; i < hitest.length; i++) { 
      hitest[i] = new Hitest(); 
      hitest[i].setGreeting("saluto numero " + i*23); 
      hitest[i].setRef(i+10); 
      hitest[i].setDate(new Date(System.currentTimeMillis())); 
      dao.save(hitest[i]); 
     } 
     tx.commit(); 
     dao.getSession().close(); 
    } 
}

和hibernate.cfg.xml的是

<?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"> 
<!-- Generated by MyEclipse Hibernate Tools.     --> 
<hibernate-configuration> 

    <session-factory> 
     <property name="hbm2ddl.auto">update</property> 
     <property name="dialect"> 
      org.hibernate.dialect.MySQLDialect 
     </property> 
     <property name="connection.url">

     </property> 
     <property name="connection.username">root</property> 
     <property name="connection.password">qwerty</property> 
     <property name="connection.driver_class">

     </property> 
     <property name="myeclipse.connection.profile"> 
      mysqlJDriver 
     </property> 
     <mapping resource="sor/hibernate/Hitest.hbm.xml" /> 

    </session-factory> 

</hibernate-configuration>

而Hitest.hbm.xml是

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

      <column name="id" /> 
      <generator class="assigned" /> 
     </id> 
     <property name="greeting" type="java.lang.String"> 
      <column name="greeting" length="200" /> 
     </property> 
     <property name="date" type="java.util.Date"> 
      <column name="date" length="10" /> 
     </property> 
     <property name="ref" type="java.lang.Integer"> 
      <column name="ref" /> 
     </property> 
    </class> 
</hibernate-mapping>

我已閱讀有關的問題和我刪除了所有的尾隨線條和空間。但他們都沒有工作。我在這些文件中添加的唯一東西是Hitest.hbm.xml中的package =「sor.hibernate」屬性。路徑和...都是正確的，它們都是自動生成的。

更多信息。當我鍵入從HQL hitest，它告訴我 org.hibernate.hql.ast.QuerySyntaxException：hitest沒有映射[從hitest] 而從sor.hibernate.Hitest效果很好

請注意，「來自hitest」正在尋找「hitest」而非「Hitest」的映射。名稱區分大小寫。 –

非常感謝！它適用於「來自Hitest」 – Johnny

嘗試刪除空白處

"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd " 
                 ^-- here

而在其他任何你可能犯過同樣錯誤的地方。

我試過了但它確實和我搜索了'''沒有其他類似的實例。我沒有更改錯誤 – Johnny

堆棧跟蹤中的這條線很奇怪：http：// www .jboss.org/dtd/hibernate/hibernate-mapping-4.0.dtd％20。這個URL在哪裏被引用？看起來最後有一個多餘的空白（％20）。 –

@JB_Nizet：移除你擁有的空間注意：我更改了db-name，並且嘗試了一個新的連接，實際上新的錯誤是這樣的：http://pastebin.com/ghWF66nQ – Johnny

解決@JB_Nizet指出的問題我遇到了關於驗證的新錯誤。（注意：空間問題是一個myeclipse錯誤，我嘗試了一個項目，它是myeclipse，它添加了這個邪惡空間。）我在hibernate.cfg.xml中添加了以下代碼，問題部分解決了。新的錯誤是（%%%%錯誤創建的SessionFactory %%%% org.hibernate.HibernateException：將錯誤BeanValidation關係約束）

<property name="javax.persistence.validation.mode">none</property>

新的錯誤是休眠的SQL查詢錯誤。該id應該已被分配，因此我將Hitest.hbm.xml更改爲

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

      <column name="id" /> 
      <generator class="increment" /> 
     </id> 
     <property name="greeting" type="java.lang.String"> 
      <column name="greeting" length="200" /> 
     </property> 
     <property name="date" type="java.util.Date"> 
      <column name="date" length="10" /> 
     </property> 
     <property name="ref" type="java.lang.Integer"> 
      <column name="ref" /> 
     </property> 
    </class> 
</hibernate-mapping>
