一.以下介绍Spring中直接集成JOTM提供JTA事务管理、将JOTM集成到Tomcat中。
（经过测试JOTM在批量持久化时有BUG需要修改源码GenericPool类解决)！
参考文章http://mavin.zhou.blog.163.com/blog/static/114522435200971822334475/
通过集成JOTM，直接在Spring中使用JTA事务
JOTM(Java Open Transaction Manager)是ObjectWeb的一个开源JTA实现，它本身也是开源应用程序服务器JOnAS(Java Open Application Server)的一部分，为其提供JTA分布式事务的功能。
Spring 2.0附带的依赖类库中虽然包含jotm类库，但是并不完整，你可以到http://jotm.objectweb.org下载完全版的JOTM。
Spring为JOTM提供了一个org.springframework.transaction.jta.JotmFactoryBean支持类，通过该支持类可以方便地创建JOTM本地实例。
1.将jotm的jar包lib目录下所有jar复制到项目中
2.将jotm的jar包conf目录下carol.properties文件复制到项目类路径下,修改内容为:
#
do not use CAROL JNDI wrapper
carol.start.jndi
=
false
#
do not start a name server
carol.start.ns
=
false
#
Naming Factory
carol.jndi.java.naming.factory.url.pkgs
=
org.apache.naming
3.建立两个数据库，配置两个数据源
<!--
XAPool配置，内部包含了一个XA数据源，对应相应的数据库
-->
<
bean
id
="mysqlJta"
class
="org.enhydra.jdbc.pool.StandardXAPoolDataSource"
destroy-method
="shutdown"
>
<!--

-->

<

value
="jdbc:oracle:thin:@localhost:1521:orcl"
/>
<
property
name

value

/>
<
property
name

value

/>
</
bean
>
</
property

<

<

二.以下介绍Spring中直接集成Atomikos提供JTA事务管理、将Atomikos集成到Tomcat中。(经过测试推荐此方法)
Atomikos Transactions Essentials现在的版本是3.1.7,可以在http://www.atomikos.com/Main/TransactionsEssentialsDownloadForm 下载，在发布包里的examples文件夹下面有些例子，非常实用，我在使用中参考里面的例子很容易配置成功。1.将Atomikos的jar包dist目录下所有jar复制到项目中
2.建立两个数据库，配置两个数据源。
Atomikos数据源配置方法有三种分别有：SimpleDataSourceBean,AtomikosDataSourceBean,AtomikosNonXADataSourceBean可任选一种
Simple表示基础数据库连接配置
<
bean
id
="oracleJta"
class
="com.atomikos.jdbc.SimpleDataSourceBean"
init-method
="init"
destroy-method
="close"
>
<
property
name
="uniqueResourceName"
>
<
value
>
OracleXADataSource
</
value
>
<!--
任意命名，但必须唯一
-->
</
property
>
<
property
name
="xaDataSourceClassName"
>
<
value
>
oracle.jdbc.xa.client.OracleXADataSource
</
value
>
</
property
>
<
property
name
="xaDataSourceProperties"
>
<
value
>
URL=jdbc:oracle:thin:@localhost:1521:orcl;user=orcl;password=
</
value
>
</
property
>
<
property
name
="exclusiveConnectionMode"
>
<
value
>
true
</
value
>
</
property
>
<
property
name
="connectionPoolSize"
>
<
value
>
3
</
value
>
</
property
>
<
property
name
="validatingQuery"
>
<
value
>
SELECT 1
</
value
>
</
property
>
</
bean
>
Atomikos表示必须要用到XA数据库驱动类,可设置连接池(经过测试推荐此方法)
<
bean
id
="oracleJta"
class
="com.atomikos.jdbc.AtomikosDataSourceBean"
init-method
="init"
destroy-method
="close"
lazy-init
="true"
>
<
property
name
="uniqueResourceName"
>
<
value
>
OracleXADataSource
</
value
>
</
property
>
<
property
name
="xaDataSourceClassName"
>
<
value
>
oracle.jdbc.xa.client.OracleXADataSource
</
value
>
</
property
>
<
property
name
="xaProperties"
>
<
props
>
<
prop
key
="URL"
>
jdbc:oracle:thin:@localhost:1521:orcl
</
prop
>
<
prop
key
="user"
>
orcl
</
prop
>
<
prop
key
="password"
></
prop
>
</
props
>
</
property
>
<
property
name
="poolSize"
><
value
>
1
</
value
></
property
>
<
property
name
="maxPoolSize"
><
value
>
30
</
value
></
property
>
</
bean
>
AtomikosNon表示必须要用到普通数据库驱动类,可设置连接池
<
bean
id
="oracleJta"
class
="com.atomikos.jdbc.nonxa.AtomikosNonXADataSourceBean"
>
<
property
name
="uniqueResourceName"
><
value
>
OracleXADataSource
</
value
></
property
>
<
property
name
="user"
><
value
>
orcl
</
value
></
property
>
<
property
name
="password"
><
value
></
value
></
property
>
<
property
name
="url"
><
value
>
jdbc:oracle:thin:@192.168.1.217:1521:orcl
</
value
></
property
>
<
property
name
="driverClassName"
><
value
>
oracle.jdbc.OracleDriver
</
value
></
property
>
<
property
name
="poolSize"
><
value
>
1
</
value
></
property
>
<
property
name
="borrowConnectionTimeout"
><
value
>
60
</
value
></
property
>
</
bean
>
另外一个数据库在这就不在写了，设置同上只是mysql的驱动类名为：xaDataSourceClassName:com.mysql.jdbc.jdbc2.optional.MysqlXADataSource
3.事务配置
Atomikos事务方法
<
bean
id
="atomikosTransactionManager"
class
="com.atomikos.icatch.jta.UserTransactionManager"
init-method
="init"
destroy-method
="close"
>
<
property
name
="forceShutdown"
>
<
value
>
true
</
value
>
</
property
>
</
bean
>
<
bean
id
="atomikosUserTransaction"
class
="com.atomikos.icatch.jta.UserTransactionImp"
>
<
property
name
="transactionTimeout"
value
="240"
/>
</
bean
>
<
bean
id
="transactionManager"
class
="org.springframework.transaction.jta.JtaTransactionManager"
>
<
property
name
="transactionManager"
>
<
ref
bean
="atomikosTransactionManager"
/>
</
property
>
<
property
name
="userTransaction"
>
<
ref
bean
="atomikosUserTransaction"
/>
</
property
>
</
bean
>
接下来的代码和上例类同就不再写。
