1.问题描述
搭建SSH框架后，为测试事务配置是否生效，因此在事务配置中取消了保存方法，然后再保存方法中手动抛出异常（已测试配置事务后没有保存成功），查看是否保存成功，如果保存成功则说明事务配置生效。但是测试保存时报错如下：

2.解决方案：
因为Spring-orm.jar中提供的Hibernate支持中有一个OpenSessionInViewFilter拦截器，用来获取Hibernate的Session，一直保持这个Session，直到请求结束。
它默认是给没有配置事务边界的方法都默认为只读的，所以没有配置事务的方法是不能对数据进行修改的。（也侧面验证了我配置的事务起作用了）
如果想方法不存在事务也可以修改数据的话，可以给该方法设置事务边界以解决该问题（不推荐）
