在 Netbeans 中调试 Maven Java 应用程序时出现问题

Question

我正在 Netbeans 中开发 Netbeans Maven Java 应用程序。我在 Hibernate 上工作时遇到了这些错误。我使用 hibernate.cfg.xml 作为 Hibernate 配置，并在 hibernate.cfg.xml 文件中定义了 sql 服务器的 sqljdbc4 驱动程序。我的问题是，MSSQL 驱动程序是否有任何问题或依赖关系或 hibernate.cfg.xml 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>

Answer 1

看起来（根据堆栈跟踪中的行号）您使用了 Hibernate 5。我可以做一个假设——在HibernateUtil中你使用Hibernate 4配置的方式配置Hibernate 5。这是完全不正确的，请参阅 this 以获取有关配置 Hibarnate 5.

的信息

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