(1) hibernate.connection.provider_class定义Hibernate的连接加载类,这里Proxool连接池是用这个,不同的连接池有不同的加载类,可以查阅Hibernate文档获取相关信息 "J=A(w5
h!!7LPxt
(2) hibernate.proxool.pool_alias这里就是用我们上面提到的连接池的别名 A`I ;m0<
HX`>"
?{
(3) hibernate.proxool.xml是向Hibernate声明连接池的配置文件位置,可以用相对或绝对路径,用相对路径时要注意一定在要Path范围内!不然会抛出异常。 >hFg,5 _l3
hgU#2`fS
(4) dialect是声明SQL语句的方言 &UextG
