JBOSS中DataSource的设置与查找

从G:\jboss-4.2.3.GA\docs\examples\jca\mysql-ds.xml拷贝文件到server\all\deploy下，修改文件内容。

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

<!-- $Id: mysql-ds.xml 71535 2008-04-01 07:05:03Z [e-mail] $ -->
<!--  Datasource config for MySQL using 3.0.9 available from:
http://www.mysql.com/downloads/api-jdbc-stable.html
-->

<datasources>
  <local-tx-datasource>
    <jndi-name>MySqlDS</jndi-name>
	<use-java-context>false</use-java-context> 这是我加入的一行
    <connection-url>jdbc:mysql://localhost:3306/test</connection-url>
    <driver-class>com.mysql.jdbc.Driver</driver-class>
    <user-name>root</user-name>
    <password>123456</password>
    <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
    <!-- should only be used on drivers after 3.22.1 with "ping" support
    <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLValidConnectionChecker</valid-connection-checker-class-name>
    -->
    <!-- sql to call when connection is created
    <new-connection-sql>some arbitrary sql</new-connection-sql>
      -->
    <!-- sql to call on an existing pooled connection when it is obtained from pool - MySQLValidConnectionChecker is preferred for newer drivers
    <check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql>
      -->

    <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
    <metadata>
       <type-mapping>mySQL</type-mapping>
    </metadata>
  </local-tx-datasource>
</datasources>

 如果像上面时查找时要用

 

context.lookup("MySqlDS");

如果用@Resource(mappedName="MySqlDS");

 

如果把上面的那个值改成:

          context.lookup("java:/MySqlDS");

 

同样在用@Resource(mappedName="java:/MySqlDS");
