Distributed transaction configuration in spring3.x

Because the use of spring3.x has been for some time, the original transaction configuration is basically based on the same data source (can use a connection, in the data operation to specify multiple database operations, also be able to rollback, transaction submission, basically implement a distributed transaction processing), today specifically with the Atomikos transaction configuration , a simple test, because Atomikos this configuration data source, with the connection pool, the performance of the connection pool is not specifically tested, the original C3P0 transaction configuration removed, this is to be tested tomorrow.

Dependent Java open source packages, automatically downloaded with maven:

My configuration

<properties>
<atomikos-version>3.9.3</atomikos-version>
</properties>

<dependency>
<groupId>javax.transaction</groupId>
<artifactId>jta</artifactId>
<version>1.1</version>
</dependency>

<dependency>
<groupId>com.atomikos</groupId>
<artifactId>transactions-jdbc</artifactId>
<version>${atomikos-version}</version>
</dependency>
<dependency>
<groupId>com.atomikos</groupId>
<artifactId>transactions-jms</artifactId>
<version>${atomikos-version}</version>
</dependency>

Now write the atomikos+spring JDBC configuration for reference in future projects
