springMVC+myBatis+Atomikos 多数据源分布式事务 oracle 、mysql 、sqlserver 数据源-优快云博客

<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">这个是本人做的一个Atomikos  分布式jta事务的 小的mavenWeb项目 ，包含 mysql 、oracle 、sqlserver 3个数据源</span>

拿一个mysql + oracle 数据源配置为例吧

database.properties

#mysql DB
mysql.qa.db.url=jdbc:mysql://localhost:3306/ssm_qa?useUnicode=true&characterEncoding=UTF-8
mysql.qa.db.user=root
mysql.qa.db.password=ROOT

mysql.dev.db.url=jdbc:mysql://localhost:3306/ssm_dev?useUnicode=true&characterEncoding=UTF-8
mysql.dev.db.user=root
mysql.dev.db.password=ROOT

#oracle DB
oracle.qa.db.url=jdbc\:oracle\:thin\:@1.1.1.32\:1521\:nyj
oracle.qa.db.driverClassName=oracle.jdbc.OracleDriver
oracle.qa.db.testQuery=select 1 from dual
oracle.qa.db.user=oms
oracle.qa.db.password=oms

oracle.dev.db.url=jdbc\:oracle\:thin\:@1.1.1.32\:1521\:nyj
oracle.dev.db.driverClassName=oracle.jdbc.OracleDriver
oracle.dev.db.testQuery=select 1 from dual
oracle.dev.db.user=com
oracle.dev.db.password=lsd


#sqlserver DB
sqlserver.qa.db.driverClass=com.microsoft.sqlserver.jdbc.SQLServerDriver
sqlserver.qa.db.url=jdbc:sqlserver://1.1.1.11:1433;DatabaseName=dl_xbny
sqlserver.qa.db.user=dl_xbny
sqlserver.qa.db.password=dl123456

sqlserver.dev.db.driverClass=com.microsoft.sqlserver.jdbc.SQLServerDriver
sqlserver.dev.db.url=jdbc:sqlserver://1.1.1.11:1433;DatabaseName=com_xbny
sqlserver.dev.db.user=com_xbny
