在spring中使用hibernate的annontation
现在初学SSH ，打的环境是struts2,spring3和hibernate4，想使用hibernate的annontation，按照网上的方法在beans.xml中做如下配置：<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource"><ref bean="dataSource" /></property>
<property name="annotatedClasses">
<list>
<value>com.user.model.User</value>
<value>com.user.model.Dept</value>
</list>
</property>
但出现Caused by: java.lang.NoClassDefFoundError: Lorg/hibernate/cache/CacheProvider;这个错误，一查说是hibernate4中已经不用CacheProvider，使用<bean id="sessionFactory"class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">配置了，那我像知道这样配置后如何使用hibernate annontation??? Hibernate Spring SSH --------------------编程问答-------------------- <bean id="mySessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> --------------------编程问答-------------------- 在dao的接口中配置这个
@Autowired
public void setSessionFactory0(SessionFactory sessionFactory) {
super.setSessionFactory(sessionFactory);
} --------------------编程问答-------------------- 试过了吗？一样用，4的LocalSessionFactoryBean是支持annotation的 --------------------编程问答--------------------
现在报could not prepare statement这个错了。。 --------------------编程问答--------------------
是不是sessionFactory的相关参数没有配置好，建议给出完整的异常 --------------------编程问答--------------------
这个还不不太理解， super.setSessionFactory(sessionFactory); 找谁的setSessionFactory方法？; --------------------编程问答--------------------

这个换成XML方式就可以运行，但是用annontation就报错。。 --------------------编程问答--------------------
这个错误是传入数据库sql的语法错误，估计annotation与正确的xml配置没有完全等价引起的 --------------------编程问答-------------------- 看这个的说明
org.springframework.orm.hibernate4
Class LocalSessionFactoryBean
public class LocalSessionFactoryBean
extends HibernateExceptionTranslator
implements FactoryBean<SessionFactory>, ResourceLoaderAware, InitializingBean, DisposableBean
FactoryBean that creates a Hibernate SessionFactory. This is the usual way to set up a shared Hibernate SessionFactory in a Spring application context; the SessionFactory can then be passed to Hibernate-based data access objects via dependency injection.
NOTE: This variant of LocalSessionFactoryBean requires Hibernate 4.0 or higher. It is similar in role to the same-named class in the orm.hibernate3 package. However, in practice, it is closer to AnnotationSessionFactoryBean since its core purpose is to bootstrap a SessionFactory from annotation scanning.
NOTE: To set up Hibernate 4 for Spring-driven JTA transactions, make sure to either specify the "jtaTransactionManager" bean property or to set the "hibernate.transaction.factory_class" property to CMTTransactionFactory. Otherwise, Hibernate's smart flushing mechanism won't work properly.
所以它是支持annotation的 --------------------编程问答--------------------
有annotation不是不需要**.hbm.xml了么？ --------------------编程问答--------------------
是不需要，xml配置方式传达给hibernate的必要信息，annotation方式也必须同样并正确地给到才不会出错，估计是annotation漏了点什么或写错了点什么
补充：Java , Java EE
