在 Netbeans 中调试 Maven Java 应用程序的问题

Question

我正在 Netbeans 中开发 Netbeans Maven Java 应用程序。我正在研究 Hibernate，我遇到了这些错误。我使用hibernate.cfg.xml作为Hibernate配置，并在hibernate.cfg.xml文件中定义了sql server的sqljdbc4驱动。我的问题是，MSSQL 驱动程序或依赖项或 hibernate.cfg.xml 是否有任何问题？

我的 hibernate.cfg.xml 包含以下代码

<?xml version="1.0" encoding="utf-8"?> 
<!DOCTYPE hibernate-configuration SYSTEM  "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
  <session-factory>
    <property name="hibernate.dialect">
      org.hibernate.dialect.SQLServer2008Dialect
    </property>
    <property name="hibernate.connection.driver_class">
      com.microsoft.sqlserver.jdbc.SqlServerDriver
    </property>    
    <!-- Assume test is the database name -->
    <property name="hibernate.connection.url">
      jdbc:sqlserver://localhost:1433;databaseName=TestDatabase;
    </property>
    <property name="hibernate.connection.username">
      sa
    </property>
    <property name="hibernate.connection.password">
      abdullah242
    </property>
    <property name="show_sql">true</property>    
    <!-- List of XML mapping files -->
    <mapping class="com.infiniteskills.data.entities.Customers" />
  </session-factory>
</hibernate-configuration>

看起来（通过堆栈跟踪中的行号）您使用Hibernate 5。我可以做一个假设——在HibernateUtil你配置Hibernate 5使用Hibernate 4配置的方式。完全不正确，配置Hibarnate 5参考this。

如果我的假设是正确的，那么异常的原因——Configuration 类在调用configure(serviceRegistry) 期间丢失了来自hibernate.cfg.xml 的所有信息，包括hibernate.dialect。
