【转】mysql在tomcat下server.xml配置


 1.将mysql-connector.jar包复制到tomcat-root/common/lib目录下
 
 2.配置连接池在tomcat-root/conf/server.xml里添加以下红色代码片段:
 <!-- 上面省略 -->
  <Host name="localhost" appBase="webapps" unpackWARs="true"    
   autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">

<Context path="/test" docBase="D:\Project\test" debug="5" reloadable="true" crossContext="true">
        <Resource name="jdbc/jie" auth="Container" type="javax.sql.DataSource"/>
        <ResourceParams name="jdbc/jie">
        <parameter><name>factory</name><value>org.apache.commons.dbcp.BasicDataSourceFactory</value></parameter>
        <parameter><name>maxWait</name><value>5000</value></parameter>
        <parameter><name>maxActive</name><value>20</value></parameter>
        <parameter><name>username</name><value>root</value></parameter>
        <parameter><name>passWord</name><value>""</value></parameter>
        <parameter><name>url</name><value>jdbc:mysql://localhost:3306/jie</value></parameter>
        <!--<parameter><name>url</name><value>jdbc:mysql://localhost:3306/lottery ?autoReconnect=true</value></parameter>-->
        <!-- <parameter><name>driverClassName</name><value>com.mysql.jdbc.Driver</value></parameter>-->
        <parameter><name>driverClassName</name><value>org.gjt.mm.mysql.Driver</value></parameter>
        <parameter><name>maxIdle</name> <value>10</value></parameter>
        </ResourceParams>
        </Context>
   </Host><!-- 下面省略 -->



3.在web.xml里添加JNDI资源的引用,代码如下:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" 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">


<description>MySQL Test App</description>
<resource-ref>
     <description>DB Connection</description>
     <res-ref-name>jdbc/jie</res-ref-name>
     <res-type>javax.sql.DataSource</res-type>
     <res-auth>Container</res-auth>
     <res-sharing-scope>Shareable</res-sharing-scope>   
</resource-ref>
</web-app>



4.页面测试test.jsp
<%@ page language="java" import="java.util.*" contentType="text/html;charset=utf-8"%>
<%@ page import="java.sql.*,javax.sql.*,javax.naming.*"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>    
<head>       
<title>Tomcat5.5连接池测试</title>    
</head>    
<body>
<%  Context initCtx = new InitialContext();           
 Context envCtx = (Context) initCtx.lookup("java:comp/env");            
 DataSource ds = (DataSource) envCtx.lookup("jdbc/EmployeeDB");            
 Connection conn = ds.getConnection();            
 Statement sta = conn.createStatement();           
  ResultSet rs = sta.executeQuery("select * from authors");          
   while (rs.next())
   {               
     out.println(rs.getString("au_lname") + "<br>");           
    }           
    conn.close();  %>   
     </body>
     </html>
     
     .\;E:\Java\jdk1.5.0_05\lib\dt.jar;E:\Java\jdk1.5.0_05\lib\tools.jar;E:\Java\jdk1.5.0_05\lib\htmlconverter.jar;E:\Java\jdk1.5.0_05\lib\jsdk-24.jar;E:\Tomcat 5.0\common\lib\servlet-api.jar;E:\Tomcat 5.0\common\lib\jsp-api.jar;E:\Java\jdk1.5.0_05\lib\mysql-connector.jar;
