请教一个关于hibernateTemplate的问题
我在注入hibernateTemplate的时候总是发现它的值为null. 但是检查不出原因来。 下面是我的代码， 麻烦大家帮忙查一下

AdminUserDAOImpl.java
-------------------------------- 
package com.brolinuk.irms.DAO;
import org.springframework.dao.DataAccessException;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.sworduk.irms.admin.AdminUser;

public class AdminUserDAOImpl extends HibernateDaoSupport implements AdminUserDAO{
  public void create(AdminUser adminuser) throws DataAccessException {
  getHibernateTemplate().save(adminuser);
  }
}

applicationContext.xml
