我的spring-hibernate应用程序出错

Question

我是Spring的新手，我正在尝试使用spring和带有注释的Hibernate创建一个简单的项目（不使用配置和映射XML）。我对3天以来的错误感到不满。

这是我看到的错误..

以下是罐子清单：http://i.stack.imgur.com/18rKU.png

我曾经得到“error-creating-bean-sessionfactory -nested exception”，直到我在spring-servlet代码中改变了我的bean声明的顺序。

Answer 1

作为以下异常的解决方案

  

引起：java.lang.NullPointerException at   org.hibernate.engine.jdbc.internal.JdbcServicesImpl.configure（JdbcServicesImpl.j AVA：207）

请为sessionFactory定义以下条目

<prop key="hibernate.temp.use_jdbc_metadata_defaults">false</prop>

Answer 2

你正在混合使用hibernate3和hibernate4类：

<bean id="sessionFactory" 
      class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
                                              ^-- 4
...

<bean id="transactionManager" 
      class="org.springframework.orm.hibernate3.HibernateTransactionManager">
                                              ^-- 3

如果你正在使用Hibernate 4，请确保只使用hibernate4包中的类，或者如果你使用的是Hibernate 3，则只使用hibernate3包中的类。

此外，似乎你在JBoss中运行它。那为什么不使用它的JTA事务管理器呢？

Answer 3

上面的例外可以通过添加这个Hibernate属性来解决：

<property name="hibernate.temp.use_jdbc_metadata_defaults">false</property>

Answer 4

当你使用注释时，你必须使用AnnotationSessionFactoryBean类

更改此

  <bean id="sessionFactory"   
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

到

     <bean id="sessionFactory" 
class="org.springframework.orm.hibernate4.annotation.AnnotationSessionFactoryBean">
