jboss eap mysql_jboss-eap-6.3集成OracleDS和MySqlDS配置

jboss-eap-6.3集成OracleDS和MySqlDS

Oracl:

在D:toolsjbossjboss-eap-6.3modulessystemlayersbasecom目录下新建oraclemain文件夹:

在此文件夹下添加ojdbc14-10.2.0.4.0.jar和module.xml,内容如下:

3. 修改D:toolsjbossjboss-eap-6.3standaloneconfigurationstandalone.xml文件,添加如下代码:

jdbc:oracle:thin:@127.0.0.1:1521:ORCL

oracle

false

false

FailingConnectionOnly

scott

tigger

oracle.jdbc.driver.OracleDriver

com.mysql.jdbc.Driver

MySql:

在D:toolsjbossjboss-eap-6.3modulessystemlayersbasecom目录下新建mysqlmain文件夹:

在此文件夹下添加mysql-connector-java-5.1.29.jar(注意:使用5.1.29以上的版本会报错,详见本文扩展部分)和module.xml,内容如下:

3.修改D:toolsjbossjboss-eap-6.3standaloneconfigurationstandalone.xml文件,添加如下代码:

jdbc:mysql://127.0.0.1:3306/demo

mysql

root

root

com.mysql.jdbc.Driver

com.mysql.jdbc.jdbc2.optional.MysqlXADataSource

扩展:

集成mysql开始时使用了:mysql-connector-java-5.1.34.jar,启动时报错:

分析错误原因,mysql驱动加载重复了,部署的JDBC 的驱动 class com.mysql.fabric.jdbc.FabricMySQLDriver正常,但紧接着又部署了一个mysql的数据源,连接mysql时驱动一般是com.mysql.jdbc.Driver,为什么现在是com.mysql.fabric.jdbc.FabricMySQLDriver呢.

换成mysql-connector-java-5.1.29.jar后就不报错了.比较了jar后得知从mysql-connector-java-5.1.30.jar开始jar中多出了fabric的驱动,在META-INFservicesjava.sql.Driver文件中包含两行

com.mysql.jdbc.Driver

com.mysql.fabric.jdbc.FabricMySQLDriver

​

而5.1.29中只包含一行

com.mysql.jdbc.Driver.

那么,fabric究竟是什么呢,见下面的文章http://www.mysql.com/products/enterprise/fabric.html
