spring+struts1.3+jpa出错

struts集成jpa时没错,通过单元测试通过.还有用的是hibernate3http://localhost:8080/工程名/
或http://localhost:8080/工程名/aa.html
这样都会出下面的错还有beans.xml中是这个
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="persistenceXmlLocation"
value="classpath:META-INF/persistence.xml" />
<property name="loadTimeWeaver">
<bean
class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver" />
</property>
</bean>具体错如下:严重: Servlet.service() for servlet default threw exception

解决方案 »

  1.   

    org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'sessionFactory' is defined 
      

  2.   

    把你的web.xml上面的openSessionInview给删除掉
    换成OpenEntityManagerInViewFilter
      

  3.   

    openSessionInviewFilter是针对hibernate3的懒加载解决方案，
    OpenEntityManagerInViewFilter是针对jpa的。
      

  4.   

    org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'sessionFactory' is defined 你没有配置sessionFactory
      

  5.   

    org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'sessionFactory' is defined 如楼上所说的,你没有配置sessionFactory, 这个sessionFactory是Hibernate3的一个类,得到sessionFactory才可以开启session,  你把这个sessionFactory交给Spring管理之后, Spring会管理session 的开启与关闭.

    这位兄台见识独到  jpa和hibernate在web.xml配置上就有这点的差异  你可以试下
