Mule是否支持带有XA事务的MySQL数据库连接池？

Question

Does Mule support MySQL database connection pooling with XA transaction? if yes could you please provide me the configuration?

Answer 1

Yes it does. You can configure it using Spring bean configuration like below.

<spring:beans>
    <spring:bean id="mySqlXADataSource" name="MySqlXADataSource" class="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource">
        <spring:property name="user" value="root" />
        <spring:property name="password" value="root" />
        <spring:property name="url" value="jdbc:mysql://localhost:3306/dev" />
    </spring:bean>
</spring:beans>

and refer the above bean definition in mule mysql connector like

<db:mysql-config name="MySQL_XA_Configuration" dataSource-ref="mySqlXADataSource" doc:name="MySQL Configuration" />

For your reference here is an example flow on XA transaction between MySQL and JMS ActiveMQ

Answer 2

Mule does support XA Transaction handling. Here's a good example with configurations.

Remember that Mule supports the transaction handling but the real work is the XML configuration of the Spring Beans (Java).
