hibernate.cfg.xml未被拾取

Question

我创建了一个maven web项目。该堆栈是Spring + Hibernate +球衣。

我在src/main/resources/path下有这个hibernate.cfg.xml。当我尝试将它部署到一个tomcat的我得到这个堆栈跟踪，

当我检查了DialectFactory.java:57，我找到的代码，

public static Dialect determineDialect(String databaseName, int databaseMajorVersion) { 
    if (databaseName == null) { 
     throw new HibernateException("Hibernate Dialect must be explicitly set"); 
    } 

所以实际的问题是，， hibernate.cfg.xml没有被加载。所以我删除了该文件并尝试部署。我再次获得了相同的堆栈跟踪。

我applicationContext.xml的是，

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

       <prop key="hibernate.default_schema">Workspacedb</prop> 
      </props> 
     </property> 
    </bean> 
</beans> 

我的hibernate.cfg.xml是，

<?xml version="1.0" encoding="utf-8"?> 
<!DOCTYPE hibernate-configuration PUBLIC

"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

     <mapping resource="Company.hbm.xml" /> 
     <mapping resource="Employee.hbm.xml" /> 
    </session-factory> 
</hibernate-configuration> 

我如何使这项工作？

谢谢。

Answer 1

根据日志，正在尝试配置Hibernate的LocalSessionFactoryBean。

同样在你的Spring配置文件中，你没有提到任何你有单独的Hibernate配置文件的地方。

所以在这个代码：

<bean id="WorkspacesDBSessionFactory" 
     class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
     <property name="hibernateProperties"> 
      <props> 
       <prop key="dialect">org.hibernate.dialect.MySQL5Dialect</prop> 
       <prop key="hibernate.default_schema">Workspacedb</prop> 
      </props> 
     </property> 
</bean> 

你是刚刚设置休眠属性dialect和hibernate.default_schema。

要解决该问题，请将属性dialect更改为hibernate.dialect。

现在，如果您仍然想使用Hibernate配置文件，那么您需要在弹簧配置文件中设置configLocation属性。

下面是关于如何使用configLocation属性的示例：

<bean id="WorkspacesDBSessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> 
     <property name="configLocation" value="classpath:hibernate.cfg.xml" /> 
    </bean> 

你可以看到详细的解释在这个职位： applicationContext.xml with datasource or hibernate.cfg.xml. Difference?

你的hibernate.cfg.xml必须在CLASSPATH挑自动启动。尝试把/ src/main/java。 由于Hibernate首先在CLASSPATH中发现默认（/ src/main/java）
