MYSQL连接池

mysql 数据库连接池亲身经验：

准备文件：

mysql-connector-java-5.0.3-bin.jar

proxool-0.9.0RC3.jar

在web.xml里添加：

 1    < servlet >
 2    < servlet - name > ServletConfigurator </ servlet - name >
 3    < servlet - class > org.logicalcobwebs.proxool.configuration.ServletConfigurator </ servlet - class >
 4    < init - param >
 5      < param - name > xmlFile </ param - name >
 6      < param - value > WEB - INF / db.xml </ param - value >
 7    </ init - param >
 8    < load - on - startup > 1 </ load - on - startup >
 9 </ servlet >
10
11 < servlet >
12    < servlet - name > proxool </ servlet - name >
13    < servlet - class > org.logicalcobwebs.proxool.admin.servlet.AdminServlet </ servlet - class >
14 </ servlet >
15
16 < servlet - mapping >
17    < servlet - name > proxool </ servlet - name >
18    < url - pattern >/ Admin </ url - pattern >
19 </ servlet - mapping >  

db.xml

16<minimum-connection-count>10</minimum-connection-count>
17<maximum-active-time>60000</maximum-active-time>
18</proxool>

含义很明了。不用多说。

在实际试用中，如正常试用mysql链接一样。

比如在jsp中添加：
<%@ page import="java.sql.*" %>
<%@ page import="org.logicalcobwebs.proxool.*" %>
<%@ page import="org.logicalcobwebs.proxool.configuration.*" %>

然后：
Connection conn = null;      
      try {
         // PropertyConfigurator.configure("Proxool.properties");
          conn = DriverManager.getConnection("proxool. test");

……
test是 配置文件中的别名。
