以jboss7.1.0和mysql为例

 

1、找到安装目录，我的目录是：jboss-as-7.1.0.CR1b

2、找到standalone.xml，这个文件在我的电脑上是C:\Users\dan\Desktop\jboss-as-7.1.0.CR1b\standalone\configuration

3、打开，并搜索datasources

4、进行编辑

<datasources>

                <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS_Pooll"  

    enabled="true" jta="true" use-java-context="true" use-ccm="true">

                    <connection-url>jdbc:mysql://localhost:3306/DBName</connection-url>                    

 

<driver>mysql</driver>

                    <pool>

<min-pool-size>5</min-pool-size>

<max-pool-size>10</max-pool-size>

<prefill>true</prefill>

<use-strict-min></use-strict-min>

     </pool>

                    <security>

                        <user-name>root</user-name>

                        <password>123456</password>

                    </security>

   <statement>

   <track-statements>true</track-statements>

         <prepared-statement-cache-size>10</prepared-statement-cache-size>

  </statement>

  <timeout>

       <idle-timeout-minutes>10</idle-timeout-minutes>

       <query-timeout>600</query-timeout>

        </timeout>

                </datasource>

                <drivers>

                    <driver name="mysql" module="com.mysql">

                        <driver-class>com.mysql.jdbc.Driver</driver-class> <xa-datasource-class>com.mysql.jdbc2.optional.MysqlXADataSource</xa-datasource-class>

                    </driver>

                </drivers>

            </datasources>

 

 

5、到E:\jboss-as-7.1.0.CR1b\modules\com文件夹下面新建一个mysql,在进入新建一个main文件夹在进入，把数据库.jar放进去

6、在这个E:\jboss-as-7.1.0.CR1b\modules\com\mysql\main文件夹里面新建一个module.xml

7、打开module.xml进行编辑

<module xmlns="urn:jboss:module:1.1" name="com.mysql">  

  <resources>

  <resource-root path="mysql-connector-java-5.0.5-bin.jar"/>

  </resources>

  <dependencies>

    <module name="javax.api"/>

    <module name="javax.transaction.api"/>

  </dependencies>

</module>

切记：path是和你的数据库jar一样的

 

8、到web中使用

<% 

     Context c=new InitialContext();

     DataSource dataSource=(DataSource) c.lookup("java:jboss/datasources/ExampleDS");

     Connection conn=dataSource.getConnection();

     PreparedStatement pstm=null;

     ResultSet rs=null;

     try{

     pstm=conn.prepareStatement("select *from score");

     rs=pstm.executeQuery();

     while(rs.next()){

     out.println(rs.getInt(1)+"<br>");

     }

     }catch(Exception e){}

    %>
