Tomcat7.0 jndi连接池的配置

测试环境: ubuntu 11.04

           Kernel: 2.6.38

           Mysql: 5.1.54

          Tomcat: 7.0

          eclipse: 3.6

          Mysql数据库驱动: mysql-connector-java-5.1.17.zip


    因为打算看看后端的数据库操作,所以就搭了环境试验一下,对于普通的数据库连接(使用JDBC的方式,比较简单,所以就试验jndi 连接池)


1.搭建好tomcat服务器

在mysql建立一个BookDB的数据库,建立一个books表,内容如下:

mysql> select * from books;

+-----+-----------+------------------------+-------+------+--------------------------------+------------+

| id  | name      | title                  | price | yr   | decription                     | saleAmount |

+-----+-----------+------------------------+-------+------+--------------------------------+------------+

| 201 | wangfang  | Java programming guide | 33.75 | 1999 | Guide user to grasp quickly    |       1001 |

| 202 | zhangbing | Weblogic tech          | 50.25 | 2000 | Good to learn web logic        |       2000 |

| 203 | sunyan    | Oracle Database        |    60 | 2002 | database entry book            |       2700 |

| 204 | Aling     | Hadoop Guide           |   100 | 2004 | A cookbook for distrbuted Arch |       5700 |

+-----+-----------+------------------------+-------+------+---------------------


2. 将Mysql驱动中得jar文件拷贝到  {TomcatHome}/lib/ 

3.   使用eclipse建立一个Dynamic Web Project

     在META-INF/ 下建立context .xml

<?xml version="1.0" encoding="UTF-8"?>

<Context>

<Resource auth="Container"

driverClassName="com.mysql.jdbc.Driver"

maxActive="100"

maxIdle="40"

maxWait="12000"

name="jdbc/BookDB"

username="root"

password="test"

type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/BookDB?characterEncoding=UTF-8" />

</Context>

 4. 在WEB-INF/ 下创建  web.xml

 <?xml version="1.0" encoding="UTF-8"?>

 <!DOCTYPE web-app PUBLIC

  '-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN'

  'http://java.sun.com/j2ee/dtds/web-app_2_3.dtd'>

<web-app> 

<resource-ref>

      <description>DB Connection</description>

      <res-ref-name>jdbc/BookDB</res-ref-name>

      <res-type>javax.sql.DataSource</res-type>

      <res-auth>Container</res-auth>

</resource-ref>

</web-app> 


5. 创建jsp文件, index.jsp

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

<%      

    Context ctx = new InitialContext();        

    String strLookup = "java:comp/env/jdbc/BookDB";   

    DataSource ds =(DataSource) ctx.lookup(strLookup);  

    Connection con = ds.getConnection();  

    if (con != null){  

        out.print("success");  

   }else{  

        out.print("failure");  

    }         

%>

 6. 运行,OK
