Question

请给出Hibernate.cfg.xml里的代码。
那个属性是设置发呆数说明一下。

<property   name="hibernate.cglib.use_reflection_optimizer"> true </property> 
                <property   name="hibernate.connection.driver_class"> oracle.jdbc.driver.OracleDriver </property> 
                <property   name="hibernate.connection.password"> genka_user </property> 
                <property   name="hibernate.connection.url"> jdbc:oracle:thin:@192.168.1.251:1521:genka </property>

                <property   name="hibernate.dialect"> org.hibernate.dialect.Oracle9Dialect </property> 
                <property   name="hibernate.show_sql"> true </property> 
这个为数据库配置 <mapping   resource="  。
这个为数据库的数据表对应生成的配置文件

Answer 3

Hibernate支持4种类型的连接池(所需要的jar包在下载的hibernate.zip压缩包中都有),具体如下：
1>hibernate自带的：
  #hibernate.connection.pool_size     连接池容量上限数目(只有这一项配置)
2>c3p0
  #hibernate.c3p0.max_size 2    最大连接数
  #hibernate.c3p0.min_size 2
  #hibernate.c3p0.timeout 5000     数据库连接对象最大持有时间（以秒为单位）
  #hibernate.c3p0.max_statements 100    最大可缓存数据库语句对象，设为0则不缓存
  #hibernate.c3p0.idle_test_period 3000
  #hibernate.c3p0.acquire_increment 2
  #hibernate.c3p0.validate false
3>proxool
  #hibernate.proxool.pool_alias pool1
##===Only need one of the following===
  #hibernate.proxool.existing_pool true
  #hibernate.proxool.xml proxool.xml
  #hibernate.proxool.properties proxool.properties
4>DBCP
  #hibernate.dbcp.maxActive    最大有效的数据库连接数
  #hibernate.dbcp.maxIdle     最大空闲的数据库连接数
  #hibernate.dbcp.maxWait     数据库连接最大可空闲时间（以毫秒为单位，设为-1则关闭）
  #hibernate.dbcp.whenExhaustedAction     当连接池的连接耗尽时的对策，为0则不予响应，为1则阻塞直到有可用的连接，为2则新增加一个连接
  #hibernate.dbcp.testOnBorrow    当从连接池获得连接时是否检验该连接有效
  #hibernate.dbcp.testOnReturn    当连接返回连接池中时，是否检验该连接有效
