我们最近从JBoss 6迁移到JBoss 7.1.1,因此从hibernate 3.6.6切换到hibernate 4.0.1,在将blob数据存储到数据库时遇到了问题.使用hibernate 3,持续约80MB的blob花费不到10秒,但是使用hibernate 4,持续时间超过1分钟.我已经尝试了几个版本的hibernate 4 - 4.0.x,4.1.x,4.2.x,行为是一样的.
环境:
jboss 7.1.1,hibernate 4.0.1,ojdbc6,Oracle DB 11.2.0.3.0 - > 1分钟
jboss 6.1.0,hibernate 3.6.6,ojdbc6,Oracle DB 11.2.0.3.0 - ~10秒
我还打开了记录到TRACE级别以查看消耗时间的位置并找到以下内容:
