hibernate + proxool整合与分开使用

hibernate+proxool整合与分别使用

让hibernate调用proxool的连接池，同时让proxool的连接池也可以在程序中直接调用，的方法

1.proxool配置，正常，如

<?xml version="1.0" encoding="utf-8"?>   
<something-else-entirely>   
    <proxool>   
        <alias>dbpool</alias>   
        <!--proxool只能管理由自己产生的连接-->   
        <driver-url>   
            jdbc:microsoft:sqlserver://xxxxxxxx;DatabaseName=xxxxxxxxx   
        </driver-url>   
        <driver-class>   
            com.microsoft.jdbc.sqlserver.SQLServerDriver    
        </driver-class>   
        <driver-properties>   
            <property name="user" value="xxxx" />   
            <property name="password" value="xxxxxxxx" />   
        </driver-properties>   
        <!-- proxool自动侦察各个连接状态的时间间隔(毫秒),侦察到空闲的连接就马上回收,超时的销毁-->   
        <house-keeping-sleep-time>90000</house-keeping-sleep-time>   
        <!-- 指因未有空闲连接可以分配而在队列中等候的最大请求数,超过这个请求数的用户连接就不会被接受-->   
        <maximum-new-connections>20</maximum-new-connections>   
        <!-- 最少保持的空闲连接数-->   
        <prototype-count>5</prototype-count>   
        <!-- 允许最大连接数,超过了这个连接，再有请求时，就排在队列中等候，最大的等待请求数由maximum-new-connections决定-->   
        <maximum-connection-count>100</maximum-connection-count>   
        <!-- 最小连接数-->   
        <minimum-connection-count>10</minimum-connection-count>   
    </proxool>   
</something-else-entirely>

2.要让自己程序直接使用proxool连接池，要在web.xml中配置启动

<servlet>   
  <servlet-name>ServletConfigurator</servlet-name>   
  <servlet-class>org.logicalcobwebs.proxool.configuration.ServletConfigurator</servlet-class>   
  <init-param>   
    <param-name>xmlFile</param-name>   
    <param-value>WEB-INF/classes/conf/Proxool.cnf.xml</param-value>   
  </init-param>   
  <load-on-startup>1</load-on-startup>   
</servlet>   
-- 下面是配置连接池的管理servlet，正式部署时候，最好去掉-->   
<servlet>   
  <servlet-name>Admin</servlet-name>   
  <servlet-class>org.logicalcobwebs.proxool.admin.servlet.AdminServlet</servlet-class>   
</servlet>   
<servlet-mapping>   
  <servlet-name>Admin</servlet-name>   
  <url-pattern>/Admin</url-pattern>   
</servlet-mapping>   

 3.hibernate的配置，如果还是正常配置

<?xml version='1.0' encoding='UTF-8'?>   
<!DOCTYPE hibernate-configuration PUBLIC    
 "-//Hibernate/Hibernate Configuration DTD 3.0//EN"    
 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">   
   
<hibernate-configuration>   
    <session-factory>   
        <property name="proxool.pool_alias">dbpool</property>   
        <property name="proxool.xml">conf/Proxool.cnf.xml</property>   
        <property name="connection.provider_class">   
            org.hibernate.connection.ProxoolConnectionProvider    
        </property>   
        <property name="connection.driver_class">   
            com.microsoft.jdbc.sqlserver.SQLServerDriver    
        </property>   
        <property name="show_sql">true</property>   
   
        <mapping resource="com/.................m.xml" />   
        <mapping resource="com/..................xml" />   
    </session-factory>   
</hibernate-configuration>   

 就会报 org.logicalcobwebs.proxool.ProxoolException:   Parsing   failed.错误

因为同名的proxool连接池已经启动，而hibernate开始运行时会自己启动关联的proxool连接池，

这时需加上

<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>   
<property name="hibernate.proxool.existing_pool">true</property>

完整的如下

<?xml version='1.0' encoding='UTF-8'?>   
<!DOCTYPE hibernate-configuration PUBLIC    
 "-//Hibernate/Hibernate Configuration DTD 3.0//EN"    
 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">   
   
<hibernate-configuration>   
    <session-factory>   
        <property name="proxool.pool_alias">cgzhpt_gy</property>   
        <property name="proxool.xml">conf/Proxool.cnf.xml</property>   
            
        <property name="dialect">org.hibernate.dialect.SQLServerDialect</property>   
        <property name="hibernate.proxool.existing_pool">true</property>   
             
        <property name="connection.provider_class">   
            org.hibernate.connection.ProxoolConnectionProvider    
        </property>   
        <property name="connection.driver_class">   
            com.microsoft.jdbc.sqlserver.SQLServerDriver    
        </property>   
        <property name="show_sql">true</property>   
   
        <mapping resource="com/jsinfo/friendlink/link.hbm.xml" />   
        <mapping resource="com/jsinfo/flashfloat/flashfloat.hbm.xml" />   
    </session-factory>   
</hibernate-configuration>
