Caused by: java.lang.IllegalArgumentException: 'sessionFactory' or 'hibernateTemplate' is required

前言：最近在写一个oa项目，用的是ssh框架，使用注解开发启动tomcat的时候报了下面错误

问题:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'departmentDao' defined in file [D:\apache-tomcat-7.0.90\webapps\oa_annotation\WEB-INF\classes\com\xiaojia\oa\dao\impl\DepartmentDaoImpl.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: 'sessionFactory' or 'hibernateTemplate' is required

分析:我的dao继承了HibernateDaoSupport  所以不能注入sessionFactory或hibernateTemplate

解决：两种方法:（1）继续使用HibernateDaoSupport    在dao类里面添加下面代码

 @Resource
	   public void setSessionFactory0(SessionFactory sessionFactory){  
	      super.setSessionFactory(sessionFactory);  
	   }

（2）dao不继承HibernateDaoSupport，直接用HibernateTemplate属性注入

@Resource(name="hibernateTemplate")
	private HibernateTemplate hibernateTemplate;

并在spring的配置文件中配置HibernateTemplate即可
