import java.util.List;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.itheima.oa.model.Department;

public class DBUtil {

private HibernateTemplate hibernateTemplate;

public HibernateTemplate getHibernateTemplate() {
    return hibernateTemplate;
}

@Resource(name = "hibernateTemplate")
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
    this.hibernateTemplate = hibernateTemplate;
}

public void findDep(){
    List li=hibernateTemplate.find("from Department");
    System.out.println(li);
}

最佳回答：

public void save(Department department) {
    // TODO Auto-generated method stub


    HibernateTemplate h=(HibernateTemplate) ToolsUtil.context.getBean("hibernateTemplate");
    System.out.println(h);
    System.out.println("實現層調用hibernateTemplate成功！");

// this.getHibernateTemplate().save(department);
System.out.println(department.getName()+"----"+department.getDescription());

    new DBUtil().findDep();

}

確定該方法執行了，控制台結果如下：
調用departmentDaoImpl成功！
org.springframework.orm.hibernate3.HibernateTemplate@2331ebb3
實現層調用hibernateTemplate成功！

通過ApplicationContext中的getBean方法拿到了hibernateTtemplate，怎麼就是不能執行save，find等方法呢，hibernateTemplate好像一直是空的
