proxool 链接sqlserver的配置【转】
<?xml version="1.0" encoding="UTF-8"?>
<!-- the proxool configuration can be embedded within your own application's.???? Anything outside the "proxool" tag is ignored. -->????<something-else-entirely>????<proxool>????????<alias>mydata</alias>????????<driver-url>???????????? jdbc:jtds:sqlserver://localhost:1433;DatabaseName=mydatabase????????</driver-url>????????<driver-class>net.sourceforge.jtds.jdbc.Driver</driver-class>????????<driver-properties>????????????<property name="user" value="sa" />????????????<property name="password" value="sa" />????????</driver-properties>????????<maximum-connection-count>20</maximum-connection-count>????????<house-keeping-test-sql>select CURRENT_DATE</house-keeping-test-sql>????</proxool></something-else-entirely>
alias是别名；
driver-url是驱动的url，就是连接的url；
driver-class是驱动的类，就是数据库驱动；
driver-properties是驱动的属性，可以设置登陆数据库的用户名和密码。
maximum-connection-count是最大连接数。
在工程的web.xml里添加如下内容：
<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/proxool.xml</param-value>????</init-param>????<load-on-startup>1</load-on-startup></servlet>这段标记是要求tomcat在启动的时候加载proxool驱动并且指明 proxool.xml的位置。
配置二：property方法
首先在WEB-INF目录下创建proxool.properties文件，内容如下：
jdbc-0.proxool.alias=mydata??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? jdbc-0.proxool.driver-class=com.microsoft.jdbc.sqlserver.SQLServerDriver
jdbc-0.proxool.driver-url=jdbc:microsoft:sqlserver://localhost:1433;databaseName=mydatabase??????????????????? jdbc-0.user=sa????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? jdbc-0.password=sa?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? jdbc-0.proxool.maximum-connection-count=20
jdbc-0.proxool.prototype-count=4
jdbc-0.proxool.house-keeping-test-sql=select CURRENT_DATE
jdbc-0.proxool.verbose=true
jdbc-0.proxool.statistics=10s,1m,1d
jdbc-0.proxool.statistics-log-level=DEBUG
在工程的web.xml里添加如下内容：
<servlet>????<servlet-name>ServletConfigurator</servlet-name>????<servlet-class>org.logicalcobwebs.proxool.configuration.ServletConfigurator</servlet-class>????<init-param>??????<param-name>propertyFile</param-name>??????<param-value>WEB-INF/proxool.properties</param-value>????</init-param>????<load-on-startup>1</load-on-startup>??</servlet>到此proxool的配置就完成了，建立链接时需要如下代码：
?? Class.forName("org.logicalcobwebs.proxool.ProxoolDriver");
??? Connection conn = DriverManager.getConnection("proxool.mydata");??? //mydata为alias中的别名
其它配置属性：
maximum-connection-lifetime?? 最大连接生命周期 默认值：4小时
maximum-active-time：????? 最大活动时间??? 默认值：5分钟
maximum-connection-count??? 最大连接数???? 默认值：15个
minimum-connection-count??? 最小连接数???? 默认值：5个
