Proxool连接池

１、 修改原来的 dataSource

< beanid = "dataSource"

       class ="org.logicalcobwebs.proxool.ProxoolDataSource">

       < property name = "driver" >

           < value > ${proxool.driver} </ value >

       </ property >

       < property name = "user" value = "share" ></ property>

       < property name = "password" >

           < value > ${proxool.password} </ value >

       </ property >

       < property name = "driverUrl" >

           < value > ${proxool.url} </ value >

       </ property >

       < property name = "alias" >

           < value > ${proxool.alias} </ value >

       </ property >

       < property name = "houseKeepingSleepTime" >

           < value > ${proxool.houseKeepingSleepTime} </ value >

       </ property >

       < property name = "prototypeCount" >

           < value > ${proxool.prototypeCount} </ value >

       </ property >

       < property name = "maximumConnectionCount" >

           < value > ${proxool.maximumConnectionCount} </ value >

       </ property >

       < property name = "minimumConnectionCount" >

           < value > ${proxool.minimumConnectionCount} </ value >

       </ property >

       < property name = "trace" >

           < value > ${proxool.trace} </ value >

       </ property >

       < property name = "verbose" >

           < value > ${proxool.verbose} </ value >

       </ property >

    </ bean >

 

１、 不推荐用 使用官方的jdbc 驱动 SQLServerDriver, 因为与连接池 proxool 一起使用出现了错误。

２、 加入 jtds.jar 包

复制 jtds.jar 到 WEB-INF/lib 目录下，用到的驱动是 net.sourceforge.jtds.jdbc.Driver

３、 配置 proxool.properties

配置后，放置在 WEB-INF 目录下，对应 < value > /WEB-INF/proxool.properties </ value >这个地方

内容如下：

proxool.database= share

proxool.alias= proxool_vange

#proxool 的一个 Bug, 要直接写到连接符里面

proxool.username= Vange

proxool.password= vangelee

proxool.driver= net.sourceforge.jtds.jdbc.Driver

proxool.url= jdbc : jtds:sqlserver://127.0.0.1:1433/${proxool.database};user=${proxool.username};password=${proxool.password}

proxool.houseKeepingSleepTime= 40000

proxool.house-keeping-test-sql= selectCURRENT_DATE

proxool.maximumConnectionCount= 10

proxool.minimumConnectionCount= 3

proxool.maximum-connection-lifetime= 18000000

proxool.simultaneous-build-throttle= 5

proxool.recently-started-threshold= 40000

proxool.overload-without-refusal-lifetime= 50000

proxool.maximum-active-time= 60000

proxool.verbose= true

proxool.trace= true

proxool.fatal-sql-exception= Fatalerror

proxool.prototypeCount= 2

４、 加入属性自动读取

< beanid = "propertyConfigurer"      class = "org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"

       lazy-init ="false" >

       < property name = "locations" >

           < list >

              < value > /WEB-INF/proxool.properties </ value >

           </ list >

       </ property >

    </ bean >
