Junit+spring+hibernate HibernateDaoSupport测试问题

  今天在用Junit做测试时，调用HibernateDaoSupport的load方法，出现no session错误，开始以为sessionFactory没注入进，后来经逐步跟踪调试发现，hibernateTemplate在load之后会立即关闭session，调用关闭的代码：

public static void initDeferredClose(SessionFactory sessionFactory) {Assert.notNull(sessionFactory, "No SessionFactory specified");logger.debug("Initializing deferred close of Hibernate Sessions");Map holderMap = (Map) deferredCloseHolder.get();if (holderMap == null) {holderMap = new HashMap();deferredCloseHolder.set(holderMap);}holderMap.put(sessionFactory, new LinkedHashSet(4));}

在测试时可以不用HibernateDaoSupport，直接获取SessionFactory来控制session的状体。
