环境:5.5以后含5.5版本

在META-INF下建立文件为context.xml

<Resource name="mysql"

auth="Container"

type="javax.sql.DataSource"

url="jdbc:mysql://localhost:3306/test"

initialSize="2"

maxActive="20"

maxIdle="20"

minIdle="2"

maxWait="10000"

removeAbandoned="true"

username="root"

password="123456"

driverClassName="com.mysql.jdbc.Driver"

Context>

测试连接池：

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%@ page import="javax.naming.NamingException" %>

<%@ page import="javax.naming.InitialContext" %>

<%@ page import="javax.naming.Context" %>

DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

head>

<body>

javax.sql.DataSource ds = null;

Context ctx = new InitialContext();

ds = (javax.sql.DataSource) ctx.lookup("java:comp/env/mysql");

<%=

ds.getConnection()
