Spring 3.1.1 + Struts 2.3.1.2 + Hibernate 4.1 整合(SSH)

2012-07-27 19:05 519 查看
最近一直有朋友在问,最新版的Spring、Struts、Hibernate整合老是有问题,昨晚大概看了一下。从Hibernate 4 开始,本身已经很好的实现了数据库事务模块,而Spring也把Hibernate4之后的HibernateDaoSupport去掉了,Spring建议使用官方的HibernateAPI进行操作。这样一来,以前习惯使用HibernateDaoSupport来操作的人来说刚刚开始可能有些不习惯。我跟据官方的说明,大概的整合一下。

现在把主要的代码和配置贴出来,供大家参考,其它配置文件和代码和以前没有什么大变化,直接就能用,主要就是Dao。

#acquireIncrement: 当连接池中的连接耗尽的时候一次同时获取的连接数。Default: 3
#idleConnectionTestPeriod:检查数据库连接池中控线连接的间隔时间,单位是分,默认值:240,如果要取消则设置为0
#idleMaxAge:连接池中未使用的链接最大存活时间,单位是分,默认值:60,如果要永远存活设置为0
#maxConnectionsPerPartition:每个分区最大的连接数
#minConnectionsPerPartition:每个分区最小的连接数
#partitionCount:分区数,默认值2,最小1,推荐3-4,视应用而定
#acquireIncrement:每次去拿数据库连接的时候一次性要拿几个,默认值:2
#statementsCacheSize:缓存prepared statements的大小,默认值:0
#releaseHelperThreads:每个分区释放链接助理进程的数量,默认值:3,除非你的一个数据库连接的时间内做了很多工作,不然过多的助理进程会影响你的性能
