代码如下 DataDao：
public class DataDao {

public void getMkmDetail(){
      persistentDetail();
}

@Transactional
public void persistentDetail(){
         //获取current session
         System.out.println(hibernateUtil.getSession("current"));
      }
}

调用方法及结果：
调用方法一：
public class DataLoader {
public static void main(String[] args) throws InterruptedException {
ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
DataDao dd = (DataDao) ctx.getBean("dataDao");
dd.persistentDetail();
      }

结果：可以打印session对象
SessionImpl(PersistenceContext[entityKeys=[],collectionKeys=[]];ActionQueue[insertions=org.hibernate.engine.spi.ExecutableList@1fbb60ad updates=org.hibernate.engine.spi.ExecutableList@46c80e21 deletions=org.hibernate.engine.spi.ExecutableList@7817bcd4 orphanRemovals=org.hibernate.engine.spi.ExecutableList@5e6e3fe4 collectionCreations=org.hibernate.engine.spi.ExecutableList@1824c22b collectionRemovals=org.hibernate.engine.spi.ExecutableList@1547a16f collectionUpdates=org.hibernate.engine.spi.ExecutableList@11b78953 collectionQueuedOps=org.hibernate.engine.spi.ExecutableList@2898b13b unresolvedInsertDependencies=UnresolvedEntityInsertActions[]])

调用方法一：
public class DataLoader {
public static void main(String[] args) throws InterruptedException {
ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
DataDao dd = (DataDao) ctx.getBean("dataDao");
dd.getMkmDetail();
      }

结果：Exception in thread "main" org.hibernate.HibernateException: No Session found for current thread


求解 为什么直接调用可以，用方法间接调用就不行了
