DBCP连接池测试用例（8月修正版）
系统：
WIN2000>>APACHE TOMCAT5.0.28(要求5.0及以上版本)>>SQL SERVER 2000
系统用的是SQL SERVER 库中的Northwind。采用第四类驱动，驱动类放到D:/testpool/WEB-INF/lib中。
保证TOMCAT和SQL SERVER正常运行。
[1]在%TOMCAT_HOME%/conf/Catalina/localhost/目录下建一个testPool.xml文件：
<?xml version='1.0' encoding='utf-8'?>
<Context docBase="D:/testpool" path="/testpool" privileged="true" workDir="work/Catalina/localhost/testpool">
<Resource type="javax.sql.DataSource" auth="Container" name="jdbc/northwind"/>
<ResourceParams name="jdbc/northwind">
<parameter>
<name>maxWait</name>
<value>5000</value>
</parameter>
<parameter>
<name>maxActive</name>
<value>4</value>
</parameter>
<parameter>
<name>password</name>
<value>123456</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc:microsoft:sqlserver://10.0.0.168:1433;databaseName=Northwind</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>com.microsoft.jdbc.sqlserver.SQLServerDriver</value>
</parameter>
<parameter>
<name>maxIdle</name>
<value>2</value>
</parameter>
<parameter>
<name>username</name>
<value>sa</value>
</parameter>
</ResourceParams>
</Context>
[2]在D:/testpool/WEB-INF/下面建立一个web.xml文件:
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<!--ConnectionPool-->
<resource-ref>
<res-ref-name>jdbc/northwind</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</web-app>
[3]在D:/testpool/下面建立测试文件index.jsp
<%@ page contentType="text/html;charset=GB2312"%>
<%@ page import="java.sql.*"%>
<%@ page import="javax.sql.*"%>
<%@ page import="javax.naming.*"%>
<%@ page session="false" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>tetst connection pool</title>
<%
out.println("我的测试开始");
DataSource ds = null;
try{
InitialContext ctx=new InitialContext();
ds=(DataSource)ctx.lookup("java:comp/env/jdbc/northwind");
Connection conn = ds.getConnection();
Statement stmt = conn.createStatement();
String strSql = " select * from Categories";
ResultSet rs = stmt.executeQuery(strSql);
while(rs.next()){
out.println(rs.getString(1));
}
out.println("我的测试结束");
}
catch(Exception ex){
out.print("出现例外，信息是:"+ex.getMessage());
ex.printStackTrace();
}
%>
</head>
<body>
</body>
</html>
[4]补充：做配置时大体要搞清楚类似的几个问题，就是考虑WWW原则，要建或改什么文件(WHO)，在那里做(WHERE)，做什么(WHAT).与之对应的是：
|
WHO |
WHERE |
WHAT |
|
testPool.xml |
%TOMCAT_HOME%/conf/Catalina/localhost/ |
见第一步 |
|
web.xml(名字固定) |
D:/testpool/WEB-INF/web.xml |
见第二步 |
|
index.jsp |
D:/testpool/index.jsp |
见第三步 |
[5]如果使用hibernate,除作上面的外还需要更改hibernate.cfg.xml文件：
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">
<!-- DO NOT EDIT: This is a generated file that is synchronized -->
<!-- by MyEclipse Hibernate tool integration. -->
<hibernate-configuration>
<session-factory>
<!-- properties

<property name="connection.url">
