注意：该方法只限于web项目

第一步：下载jar包，导包

第二部：写配置文件

jdbc-1.proxool.alias=test
#jdbc-1.proxool.driver-class=com.mysql.jdbc.Driver
#jdbc-1.proxool.driver-url=jdbc:mysql://127.0.0.1:3306?useUnicode=true&characterEncoding=utf8
jdbc-1.proxool.driver-class=com.mysql.jdbc.Driver
jdbc-1.proxool.driver-url=jdbc:mysql://localhost:3306/hechen
jdbc-1.user=root
jdbc-1.password=root
jdbc-1.proxool.maximum-connection-count=100
jdbc-1.proxool.minimum-connection-count=5
jdbc-1.proxool.prototype-count=4
jdbc-1.proxool.verbose=true
jdbc-1.proxool.statistics=10s,1m,1d
jdbc-1.proxool.statistics-log-level=error

第三步：配置web.xml文件

在web.xml下添加如下代码

 <!-- Web项目中配置proxool，并自动加载 -->
  <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/classes/proxool.properties</param-value>
     </init-param>
     <load-on-startup>1</load-on-startup> 

</servlet>
    <!--  监控 proxool 连接池 -->
<servlet>
  <servlet-name>AdminServlet</servlet-name>
  <servlet-class>org.logicalcobwebs.proxool.admin.servlet.AdminServlet</servlet-class>
</servlet>

第四步：创建连接

public class DButil {
static String url = "jdbc:mysql://localhost:3306/hechen";
static Connection connection = null;


public static Connection getConnection() {


try {

// 常规jdbc建立连接
//Class.forName("com.mysql.jdbc.Driver");  

                        //connection = DriverManager.getConnection(url, "root", "root");

//proxool数据库连接池建立连接

Class.forName("org.logicalcobwebs.proxool.ProxoolDriver");
connection = DriverManager.getConnection("proxool.test");

} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return connection;


}

第五步：测试

成功连接！！
