SSH整合报错：Write operations are not allowed in read-only mode (FlushMode.MANUAL)

初学SSH，开发示例发现报错：Write operations are not allowed in read-only mode (FlushMode.MANUAL)，看报错信息大概知道是HibernateTemplate.save保存数据时无写的权限，在网上查了很多，试了几个方法都得不通，最终发现，需要同时修改ApplicationContext.xml和web.xml两个文件，问题解决。

web.xml增加以下配置：

	         OpenSessionInViewFilter
	         org.springframework.orm.hibernate5.support.OpenSessionInViewFilter
	         
	                   sessionFactoryBeanName
	                   sessionFactory
	         
	         
	                   singleSession
	                   true
	         
	         
	                   flushMode
	                   AUTO 
	         
	
	
	         OpenSessionInViewFilter
	         /*
	

ApplicationContext.xml增加以下配置：
