org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread

緣由不詳：

解決方法：

一是在web.xml添加：

   
   
   
   

    
    
    
    

    
    
    
    

    
    
    
    

    
    
    
    

    
    
    
    

    
    
    
    

    
    
    
    

    
    
    
    

    
    
    
    

    
    
    
    

    
    
    
    

    
    
    
    

    
    
    
    

    
    
    
    

    
    
    
    

    
    
    
    

   
   
   
   
<filter> <filter-name>hibernateFilter</filter-name> <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class> <init-param> <param-name>singleSession</param-name> <param-value>true</param-value> </init-param> <init-param> <param-name>flushMode</param-name> <param-value>AUTO</param-value> </init-param> </filter> <filter-mapping> <filter-name>hibernateFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>

還沒那麼深刻了解，對這種方法表示像喝白開水，不感冒。

仍是方法二好理解點：

1 2 3

添加：   @Transactional(propagation = Propagation.REQUIRED)

不過，記得還要在spring的配置文件上添加

1	<tx:annotation-driven transaction-manager= "transactionManager" />

否則單單添加     @Transactional也沒有用的！！
