'sessionFactory' or 'hibernateTemplate' is required

Question

用注解自动注入可以成功代码public class CommonDaoImpl<T> extends HibernateDaoSupport implements ICommonDao<T> { public void save(T t) {
this.getHibernateTemplate().save(t);
}
// @Resource(name="sessionFactory")
// public final void setSessionFactoryMe(SessionFactory sessionFactory){
// super.setSessionFactory(sessionFactory);
// }}
如果用beans.xml注入会报错：注入代码
  <bean id="commonDaoImpl" class="cn.jin.elec.dao.impl.CommonDaoImpl">
      <property name="sessionFactory" ref="sessionFactory"></property>
     </bean>完整报错是：org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cn.jin.elec.dao.impl.ElecTextDaoImpl' defined in file [D:\Workspaces\jinelel2\WebRoot\WEB-INF\classes\cn\jin\elec\dao\impl\ElecTextDaoImpl.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: 'sessionFactory' or 'hibernateTemplate' is required

Answer 1

<bean id="userDao" class="com.test.dao.impl.UserDAOImpl" scope="singleton">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean><bean id="userService" class="com.test.service.impl.UserServiceImpl">
<property name="userDao" ref="userDao"></property>
</bean>类似这么写

Answer 2

注解注入和XML注入不是等价的吗？为什么注解可以，而xml注解报错？网上查了好久，答案都是差不多，没有找到解决的答案；还忘大虾帮我看下！！！

Answer 3

注解和XML不一样的 注解帮你实现很多东西，XML要求你手动注入，并不是配一个bean就完事了。

Answer 4

public class CommonDaoImpl<T> extends HibernateDaoSupport implements ICommonDao<T> {
        private sessionFactory sessionfactory;
        实现 sessionfactory的set和get方法 public void save(T t) {
this.getHibernateTemplate().save(t);
}
// @Resource(name="sessionFactory")
// public final void setSessionFactoryMe(SessionFactory sessionFactory){
// super.setSessionFactory(sessionFactory);
// }}

Answer 5

这里的sessionFactory是HibernateDaoSupport里面的，这里重写定义属性sessionFactory和setter方法，两个sessionFactory是一样的吗？

Answer 6

ElecTextDaoImpl。它报的是这个bean不能实例化，你贴的却是commonDaoImpl。

Answer 7

ElecTextDaoImpl就是这个
@Repository(IElecTextDao.SERVICE_NAME)
public class ElecTextDaoImpl extends CommonDaoImpl<ElecText> implements IElecTextDao  {
}

Answer 8

ElecTextDaoImpl就是这个
@Repository(IElecTextDao.SERVICE_NAME)
public class ElecTextDaoImpl extends CommonDaoImpl<ElecText> implements IElecTextDao  {
}
那就不清楚了，不过话说，这么多天了，还没有解决吗？
