proxool 连接池简单应用

1.下载所必需jar包。包括log4j的jar包。

2.在web.xml中加入

<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> 

注：

<init-param>

    <param-name>propertyFile</param-name>

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

  </init-param>

可以替换为

<init-param>

    <param-name>xmlFile</param-name>

    <param-value>WEB-INF/proxool.xml</param-value>

  </init-param>

 

web.xml 配置完成

3.配置文件2选1，proxool.xml 和proxool.properties的内容分别如下：

xml：

<?xml version="1.0" encoding="ISO-8859-1"?>

<proxool>

    <alias>xml-test</alias>

    <driver-url>jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=hih</driver-url>

    <driver-class>com.microsoft.jdbc.sqlserver.sqlServerDriver</driver-class>

    <driver-properties>

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

      <property name="password" value="sa"/>

    </driver-properties>

    <maximum-connection-count>10</maximum-connection-count>

    <house-keeping-test-sql>select CURRENT_DATE</house-keeping-test-sql>

  </proxool>

properties：

jdbc-0.proxool.alias=property-test 

jdbc-0.proxool.driver-url=jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=hih

jdbc-0.proxool.driver-class=com.microsoft.jdbc.sqlserver.sqlServerDriver

jdbc-0.user=sa

jdbc-0.password=sa

jdbc-0.proxool.maximum-connection-count=10

jdbc-0.proxool.house-keeping-test-sql=select CURRENT_DATE

4.得到connection的java代码：

try{

Class.forName("org.logicalcobwebs.proxool.ProxoolDriver");

Connection con = DriverManager.getConnection("proxool.xml-test");

// Connection con = DriverManager.getConnection("proxool.property-test");

return con;

}catch(Exception e){}
